Look at this glass of soda. Use your knowledge of thermal energy transfer to explain how heat is affecting the following things: ice, soda, glass, and surrounding air.
Explanation:
Technically, the ice cube melts because the water cools down. This may sound ridiculous at first, but you must consider the fact that the ice melts because it has drawn "heat" (energy) from its surroundings. The "surroundings" being the air and water that surround it (but the water's more important since it's a better conductor of thermal energy).
The surrounding air looses energy while the ice in the glass gains energy.
We know that thermal energy is transferred from a hotter body to a cooler body. If we look as the glass, we will notice that the surrounding air has a greater energy compared to the contents of the glass. The surrounding air looses this energy resulting in the condensation of water vapor in air around the glass.
Similarly, the ice in the glass gains energy and melts. A change of state occurs from solid to liquid as a result of the energy absorbed from the surrounding air.

What is the difference between a pure solvent and a solution? Do they have the same physical properties?
Answer:
The physical properties of a solution are different from those of the pure solvent. ... Colligative properties are those physical properties of solutions of nonvolatile solutes that depend only on the number of particles present in a given amount of solution, not on the nature of those particles.

How kids today make slime and why each ingredient is used. What does each ingredient do and what happens if you change how much is used?
Answer:
Find the steps and explanation below.
Explanation:
A. Kids make slime following these basic steps;
1. In a bowl, is 1/4 cup of water is added to 1 oz. of glue. Add coloring if you wish to.
2. 1/4 cup of Borax solution, also known as Sodium Tetraborate is added to the mixture and gradually stirred.
3. The mixture is kneaded with the hands to ensure a smooth consistency.
4. Water remnants are discarded and the slime is stored in a plastic bag and kept in the fridge.
B.
What each ingredient does
Polyvinyl acetate present in the glue acts as a liquid polymer.
Borax binds the liquid polymers together.
Water eases the mixing process
C.
If lesser ingredients are used, the slime will not have its characteristic slimy nature. If excess of the ingredients are used, the slime becomes very sticky.

What happens to the energy of gas particles when an elastic collision takes place?
Select one:
a.The more massive gas particle gains energy
b.The least massive gas particle looses energy
c.The more massive gas particle looses energy
d.No energy is exchanged between the gas particles
Answer:
the answer is D
Explanation:
When the elastic collision happens the particles energy does not change. There is no loss or gain of energy due to the elastic collision.
The energy of gas particles when an elastic collision takes place then "No energy is exchanged between the gas particles"
What is elastic collision?A collision between two bodies that would be elastic occurs when their combined kinetic energy stays constant.
What is energy?Energy is the ability to do tasks. It can exist in various forms, including potential, kinetic, thermal, electrical, chemical, and nuclear.
When two objects collide, there was no net loss of kinetic energy across the system. This is known as an elastic collision. In elastic collisions, momentum, as well as kinetic energy would both be conserved.
Therefore the correct answer will be option (d)

Compound X meits at 801°C and is a good electrical conductor when dissolved in water.
Compound Y boils at 77°C. is insoluble in water and is a non-conductor of electricity.
Which type of bonding is present in X and in Y?
Answer:
I'm sorry but I cant answer.
Compound X meits at 801°C and is a good electrical conductor when dissolved in water. Compound Y boils at 77°C. is insoluble in water and is a non-conductor of electricity. Compound X is ionic bonding and compound y is covalent bonding.
What is ionic bonding ?The main interaction in ionic compounds is ionic bonding, a type of chemical bonding that involves the electrostatic attraction between two atoms or ions with dramatically differing electronegativities.
The sharing of electrons between two or more atoms forms a covalent connection. When two or more ions join in contact, they can create ionic bonds that are held together by charge differences.
In most cases, ionic compounds are created when a metal reacts with a nonmetal (or a polyatomic ion). The reaction between two nonmetals produces covalent compounds. Binary compounds containing hydrogen are typically covalent compounds since hydrogen is a nonmetal.
Thus, Compound X is ionic bonding and compound y is covalent bonding.

9.32 L of pentane reacts with 36.4 L of oxygen. how many liters of carbon dioxide are formed?
Answer:
22.75 L CO2
Explanation:
Balance the Equation
C5H12 + O2 ==> CO2 + H2O Balance the Carbons
C5H12 + O2 ==> 5CO2 + H2O Now balance the Hydrogens
C5H12 + O2 ==> 5CO2 + 6H2O Now count up the oxygens on the right.
5*O2 + 6O ==> 10 O + 6 O ===> 16 Oxygens.
You have 2 on the left. You have to multiply the oxygens by 8
C5H12 + 8O2 ==> 5CO2 + 6 H2O
The equation is now balanced.
Now find out how much oxygen is needed to burn 9.32 L of Pentane
1 Liter Pentane / 8 Liters Oxygen = 9.32 L Pentane / x Cross multiply
x = 8 * 9.32
x = 74.56
Read this next sentence very carefully. You need 74.56 Liters of oxygen to burn all the pentane you have. There's not that much there. You only have 36.4 Liters of Oxygen. Some of the pentane won't get burned. Consequently there will be a shortage of CO2 as well.
Find out the number of Liters of Pentane that will be burned up.
1 / x = 8 / 36.4 Cross multiply
8x = 36.4 Divide by 8
8x/8 = 36.4/8
x = 4.55 Liters of Pentane will be used up.
Find the number of Liters of CO2
For every Liter of Pentane, 5 Liters of CO2 will be produced.
1/5 = 4.55/x Cross Multiply
x = 5 * 4.55
x = 22.75

A tank consists of a gaseous mixture of 3.83 g of triselenium diiodide, 2.62 g of ammonium telluride, and 1.82 g of iridium (i) sulfate. What is the partial pressure in atm of ammonium telluride if the total pressure in the tank is 2.795 atm?
Answer: The partial pressure in atm of ammonium telluride is 1.48 atm
Explanation:
According to Raoult's law, the partail pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the total pressure
[tex]p_A=x\times p_{total}[/tex]
where, x = mole fraction
[tex]p_A[/tex] = partial pressure of A
[tex]p_{total}[/tex] = total pressure
[tex]x_{\text {ammonium telluride}}=\frac{\text {moles of ammonium telluride}}{\text {total moles}}[/tex],
[tex]x_{\text {ammonium telluride}}=\frac{\frac{2.62g}{164g/mol}}{\frac{2.62g}{164g/mol}+\frac{3.83g}{333g/mol}+\frac{1.82g}{673g/mol}}=0.53[/tex]
[tex]p_{\text {ammonium telluride}}=0.53\times 2.795atm=1.481atm[/tex]
Thus the partial pressure in atm of ammonium telluride is 1.48 atm
