Comparing the matter that makes up its different parts.
Hope this helps! ;)
Answer:
Heat, temperature, and thermal energy are related because they all work with each other.
Explanation:
First of all, everything start's off with temperature. It starts off low. But when heat is added to it, it rises and the temperature goes up. This causes thermal energy to the objects touching it. The hotter it is the faster the particles move and the more kinetic energy they have.
Question is incomplete, the complete question is as follows:
A student wants to examine a substance by altering the bonds within its molecules. Which of the following properties of the substance should the student examine?
A. Toxicity, because it can be observed by altering the state of the substance
B. Boiling point, because it can be observed by altering the state of the substance
C. Toxicity, because it can be observed by replacing the atoms of the substance with new atoms
D. Boiling point, because it can be observed by replacing the atoms of the substance with new atoms
Answer:
B.
Explanation:
A student can examine a substance without altering the bonds within the molecules by examining its boiling point.
The boiling point is the property of a substance, at which the substance changes its state, which is from solid to liquid, liquid to gas and others. So, examining the boiling point will alter the bonds within the molecules as the state of substance will change.
Hence, the correct answer is "B".
Answer:
The average kinetic energy of a particle is proportional to the temperature in Kelvin.
Explanation:
The kinetic molecular theory states that particles of matter are in constant motion and collide frequently with each other as well as with the walls of the container.
The collisions between particles are completely elastic. The kinetic energy of the particles of a body depends on the temperature of the body since temperature is defined as a measure of the average kinetic energy of the particles of a body.
Therefore, the average kinetic energy of a particle is proportional to the temperature in Kelvin.
Answer:
stretching and thinning of the Earth's crust occurs.
Explanation:
The result of the extension stress on Earth layers is the stretching and thinning of the Earth's crust occurs.
When there is a stress on the Earth's layers, the Earth's crust experiences the phenomena of stretching and thinning.
