the ____ temperature of an object the lower its thermal energy
Thermal energy is the average sum of all kinetic energy of all the molecules of gases. The lower the temperature of an object the lower its thermal energy.
What is Thermal energy?
Thermal energy is a energy which is possess by a moving object. It is directly proportional to kinetic energy of the molecules. It is very difficult to find the correct value of kinetic energy so we find average kinetic energy. Which is very easy to calculate as compared to calculating kinetic energy.
Mathematically,
K.E=2/3KT
Where,
K= Boltzmann constant
T is the temperature
Average kinetic energy is directly proportional to temperature. It is not dependent on the type of gases or mass of gases. The lower the temperature of an object the lower its thermal energy.
Therefore, the lower the temperature of an object the lower its thermal energy.

A balloon filled with gas has a mass of 5 g. If the balloon is heated the mass of the balloon will:
--
A.) remain 5g
B.) decrease
C.) increase
Answer:
I believe the answer would be A, remain 5g because heating the balloon would increase the speed of the gas molecules, but not necessarily change the amount
Answer:
decrease
Explanation:
The ballon will most likely pop causing it to decrease in mass.
Can someone please explain how to solve it ?
Explanation:
40 m/s2
Formula for acceleration will be:
F = m*a
Force = mass*acceleration
•
•
F = m*a
= 40 * 180 - 140 = a
1600 = a
1600/40 = a
40 = a = 40 m/s2
How small are the microorganisms that live on and in the human body? Answer it in at least 1 paragraph
Answer: The human body contains trillions of microorganisms — dwarfing human cells by 10 to 1. Due to their little size, nonetheless, microorganisms make up just around 1 to 3 percent of the weight's (in a 200-pound grown-up, that is 2 to 6 pounds of microscopic organisms), yet assume a crucial function in human wellbeing. In 2016, a survey of over forty years of examination into the human microbiome found that there is zero logical proof to back this frequently refered to tidbit up. Rather, the proportion appears to be about 1.3-to-1, with the normal human playing host to around 100 trillion microorganisms, plus or minus. Rather, the proportion seems to be about 1.3-to-1, with the normal human playing host to around 100 trillion organisms, plus or minus.
Explanation:
You can mix this up and paraphrase this into ur own words.
The microorganisms that are present and live in the human body are 1 to 10 micrometers.
What are microorganisms?
Microorganisms are tiny living organisms that can be only seen by microscopes. These organisms are found everywhere on earth. They are free-living and parasitic. There are good and bad microorganisms.
Some are useful to the earth and the living creature, but some are harmful to the health of other living creatures. They are responsible for many diseases in plants, animals, and other organisms.
There are many bacteria present inside the body. They are present in the digestive system, and our mouth. They help in the digestion and breakdown of many food materials and macromolecules.
Thus, the size of microorganisms that are present and live in the human body is 1 to 10 micrometers.

Laura and Jess observed two points, P and Q, on a number line. A number line is shown from negative 2 to positive 2 with increments of 2 over 8. A point P is shown at the fifth tick mark to the left of 0, and a point Q is shown at the fifth tick mark to the right of 0. Jess said that the absolute values of the numbers represented by the two points are different. Laura said that the absolute values of the numbers represented by the two points are the same. Which of the following explains who is correct?
Jess, because the points are of different signs
Jess, because the points are at different locations
Laura, because the distance between the two points is 10 over 8 units
Laura, because each of the two points is 10 over 8 units from 0
Answer:
P is 5 ticks to the left of 0, so it would be -5/8
Q is 5 ticks to the right of 0, so it would be at 5/8
an absolute value turns a negative number into a positive number
so absolute value of P located at -5/8 = 5/8
this is the location of point Q
Jimmy said that the absolute values of the numbers represented by the two points are the same.
so Jimmy is correct

A space shuttle is covered with two layers of carbon. The two layers are the same size and have the same number of molecules. When the space shuttle is sitting on the ground, the layers do not touch, as shown in the diagram above. When the space shuttle takes off, the layers move so that they are touching. Use the information in the diagram to answer the question.
How does the temperature of the outer layer compare with the temperature of the inner layer before the layers touch? What will happen after the layers have been touching for a while?
Answer:due to the heat of it the molicules expand and therefor touch also on rentry due to heat
Explanation:
The characteristics of the thermal transfer process allow to find the results for the questions regarding the temperature in the two cases are:
When the material is separated, the transfer is carried out by radiation, the internal temperature rises slowly. When the material is bonded, the heat transfer is carried out by conduction, the interior temperature rises rapidly.
Thermal conduction processes are mechanical by which thermal energy (temperature) is transported, they ask to be of three types:
Conduction. When there is no displacement of matter, the energy is transported by the agitation of the molecules. Convection. When matter is transported, very important for liquids and gases. Radiation. When there is no physical contact and the energy is transferred by the radiation of electromagnetic waves.
At the initial moment the two layers are not touching, therefore the only possible process is radiation, therefore the outermost body may be at a very high temperature and the inner body may be cold since radiation heating is the less efficient.
When the materials touch, the energy transfer process is thermal conduction, therefore the interior temperature will increase significantly. The thermal conduction process is one of the fastest, therefore the temperature rises rapidly.
In conclusion, using the characteristics of the thermal transfer process, we can find the results for the questions regarding temperature in the two cases are:
When the material is separated, the transfer is carried out by radiation, the internal temperature rises slowly. When the material is bonded, the heat transfer is carried out by conduction, the interior temperature rises rapidly.

A student uses red litmus paper to test the pH value of different solutions. Which would result in a color change of the litmus paper?
soap
vinegar
lemon juice
antifreeze
The litmus paper shows red colour for acidic substances and blue colour for basic substances. Thus a red litmus paper will turn blue if it is dipped in an alkaline solution. Soap is alkaline and given blue color to litmus.
What is pH?pH of a substance is its measure of concentration of H+ ions in it. It is mathematically negative logarithm of H+ ion concentration. Thus, pH measures how much acidic or basic the solution is.
A pH of of 7 is neutral having no acidity or basicity. A pH less than 7 is acidic and pH greater than 7 is basic in nature. Vinegar is acetic acid and it shows less pH . Lemon juice also acidic since it contain citric acid whereas, soap is basic.
A litmus paper is used to identify whether a substance is acidic or basic. It shows red color for acidic solutions and blue for basic solutions. If the red litmus paper is dipped in acidic one, it shows no colour change if it is dipped in basic solution then it turns to blue.
Soap is highly alkaline and it changes red litmus paper to blue.
