Speed has a greater impact on mass because its increases in velocity have an exponentially greater impact on translational kinetic energy because kinetic energy is proportional to velocity squared. Doubling an object's mass would only double its kinetic energy, however doubling its momentum would quadruple its velocity.
A gas is most likely to change the liquid phase in the pressure of the gas
Answer: if pressure rises in closed vessel and temperature is low enough,
Gas may condense to liquid state
Typically, this happens when we raise the pressure at room temperature, but there are other situations that aren't covered, including lowering the temperature at room pressure.
What is temperature?Temperature is defined as a measurement of an object or substance's warmth or coldness in relation to a standard value. As opposed to extensive characteristics, like mass or volume, temperature is referred to as an intense property—one that is independent of the quantity of matter being considered—along with pressure, density, and other comparable properties.
If the temperature is low enough and pressure rises in a closed vessel, A gas can turn into a liquid form.
Thus, typically, this happens when we raise the pressure at room temperature, but there are other situations that aren't covered, including lowering the temperature at room pressure.

Consider the table below that summarizes the types of materials that can block the 3 different types of radiation. Based on the table, at which numbered spot in the table does each type of radiation belong. 1 = beta; 2 = alpha, 3 = gamma
Answer:
D. 1 = gamma; 2 = alpha, 3 = beta
Explanation:
I apologize if this answer is late, but I got answered the question right on my "Types of Radioactive Decay" quiz :)
Hope this is helpful for others! :D
Based on the table, the type of radiation belong from 1 is the gamma rays, from 2 is the aplha rays and from 3 is the beta rays.
What are radiations?During the radioactive decay process, some amount of energy is released in the form of particles and that radiations will known as alpha rays, beta rays and gamma rays.
Gamma ray are mare energetic rays and will shielded by only lead and thick concrete materials.Beta rays are less energetic than gamma rays and will shielded by lead, cloth, paper, wood, aluminium foil and thick concrete materials.Aplha rays have very less amount of energy in it and it will be shielded by all above mention materials.Hence 1 is the gamma rays, 2 is the aplha rays and 3 is the beta rays.

a ceiling fan's blades collect dust faster than other objects in a room. the constant pushing and rubbing against the air provide a cool breeze for the people in the room. what causes the ceiling fan´s blade to collect dust so quickly.
As the blades rotate, they experience frictional forces as they `rub' against the air; this knocks electrons around, causing the blades to build up a net charge. The charged dust particles then stick to the charged areas of the blades. "The leading edge of the blades usually develops the thickest layer of dust.
To solve this we must be knowing each and every concept related to dust. Therefore, frictional forces allow the ceiling fan´s blade to collect dust so quickly.
What is dust?Dust stirred up by automobiles on the road may account for 33% overall air pollution. Deposits of vehicle or commercial exhaust gas, particles through tire and braking wear, dust from paved streets or potholes, plus dust from building sites all contribute to road dust.
As the blades revolve, frictional forces cause them to 'rub' against the air, knocking electrons around and allowing the blades to accumulate a net charge. The electrified dust particles are subsequently attracted to the charged portions of the blades. Typically, the sharp end of the blades creates the heaviest coating of dust.
Therefore, frictional forces allow the ceiling fan´s blade to collect dust so quickly.

Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.

Using an analogy of a water balloon, describe the function of the bladder.
Answer:
A bladder is like a balloon, because it holds urine, just like a balloon holds air. The urethra's function is to excrete urine from the human body.
Explanation:
A bladder and a balloon are similar, because it is the bladder which clasp urine, whereas a balloon clench air. The role of urethra is to eliminate urine from our human body.
What is bladder?The hollow organ which is in triangle shape and found in the lower abdomen just like a balloon is defined as the bladder. The urinary bladder is also known as a temporary reservoir of urine. Urine is reserved in the urinary bladder till it is removed out through the urethra.
As a result of the contraction of the wall of the urinary bladder, urine is eliminated from the body from time to time. The urine contains waste and extra fluid left over the body which has to be eliminated.
The bladder resembles the water balloon in that it holds urine in the similar way as the water balloon clench water. The water balloon pops when the amount of water exceeds than it can hold.
Thus the function of bladder and water balloon are found to be same.

Se tiene un litronde solucion de agua con alcohol con una consentracion del 4.5% v/v ¿Cuanto alcohol se tiene en la solución
Answer:
45 mL
Explanation:
Tenemos los siguientes datos:
V = 1 L
C = 4,5% v/v
El porcentaje en volumen (%v/v) expresa el volumen de soluto (alcohol en este caso) que hay cada 100 mL de solución. Si la solución tiene una concentración del 4,5% v/v eso quiere decir que hay 4,5 ml de alcohol cada 100 ml de solución, de acuerdo a lo siguiente:
4,5% v/v alcohol = volumen alcohol/ volumen solución x 100 = 4,5 mL alcohol/100 mL solución= 4,5 mL alcohol/0,1 L alcohol
Por lo tanto, al multiplicar por el volumen total de la solución (1 L), obtenemos la cantidad total de alcohol:
4,5 mL alcohol/0,1 L alcohol x 1 L = 45 mL

Name the following base: NaOH
Answer:
Arrhenius Base
Explanation:
"NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH-) and sodium (Na+) ions. An Arrhenius acid is therefore any substance that ionizes when it dissolves in water to give the H+, or hydrogen, ion. ... Acids provide the H+ ion; bases provide the OH- ion; and these ions combine to form water."

How many moles of C6H12O6 does 8.2 x 1023 molecules represent
Answer:
i.e. mass of 1 mole of glucose, C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose, so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.

If 21.6 g of NO and 13.8 g of O₂ are used to form NO₂, how many moles of excess reactant will be left over? 2 NO (g) + O₂ (g) → 2 NO₂ (g)
Answer: 0.071 moles of excess reactant [tex](O_2)[/tex] will be left over.
Explanation:
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
a) moles of [tex]NO[/tex]
[tex]\text{Number of moles}=\frac{21.6g}{30.01g/mol}=0.720moles[/tex]
b) moles of [tex]O_2[/tex]
[tex]\text{Number of moles}=\frac{13.8g}{32g/mol}=0.431moles[/tex]
[tex]2NO(g)+O_2(g)\rightarrow 2NO_2(g)[/tex]
According to stoichiometry :
2 moles of [tex]NO[/tex] require 1 mole of [tex]O_2[/tex]
Thus 0.720 moles of [tex]NO[/tex] require=[tex]\frac{1}{2}\times 0.720=0.360moles[/tex] of [tex]O_2[/tex]
Thus [tex]NO[/tex] is the limiting reagent as it limits the formation of product and [tex]O_2[/tex] is the excess regaent.
moles of [tex]O_2[/tex] left = (0.431-0.360) = 0.071 moles
