What happens to the thermal energy of a substance as its temperature increases?
When a sample of a substance absorbs thermal energy, its temperature rises.
Why does temperature stay the same during a phase change?
The temperature, in Physics, means the measure of Kinetic Energy in a substance. When a substance is either heated or cooled, Kinetic Energy is either being added to taken away from the substance. When the amount of KE in the substance changes, the temperature change. However, when the substance is changing its state, because all the KE change in the substance is being used up to change the state, the temperature will not change. When the substance is changing state, the KE can be measured by calculating the heat of fusion and heat of vaporization.
When energy enters a substance what is it called?
The electrons of different atoms start moving due to the change in kinetic energy. This produces a rise in the temperature of the substance. Each substance will have different reactions to the temperature changes{THIS WAS NOT MY ANSWER}
Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
What is the relationship between energy and temperature change?
When heat is transferred in a space the average energy of the particles - the temperature of the substance - is affected, by increasing or decreasing. The change in temperature depends on the number of particles affected.
What happens to the thermal energy of a substance as its temperature increases?
When a sample of a substance absorbs thermal energy, its temperature rises.
What absorbs and radiates energy with the least amount of temperature change?
Neutronium
What describes the behavior of a substance during a phase change?
It either absorbs or releases energy
How does a substance 's temperature change when the average kinetic energy of it's particle increases?
As the average kinetic energy of a substance increases, the temperature will increase.
Does the energy content of a substance change during a phase change?
Yes, but not the temperature.
Which may be true for a substance that absorbs energy?
The energy decreases the molecular motion and the kinetic energy of the substance.
Is temperature change chemical?
No. Temperature is not a change of any sort. It is a measure of the average kinetic energy of the particles in a substance.
Is temperature a form of energy?
Temperature is not a form of energy, but a measurement of energy (specifically, heat energy). You can't add temperature to a substance, because every substance already has a temperature, whether it be at -50o C or 900o C. However, you can add heat to change the temperature.
What is an amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy?
The amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy is 42,2g H2O.

When the amount of KE in the substance changes, the temperature change. However, when the substance is changing its state, because all the KE change in the substance is being used up to change the state, the temperature will not change. When the substance is changing state, the KE can be measured by calculating the heat of fusion and heat of vaporization.
Why does evaporation require that heat energy be added to a substance?
Heat is energy the substance needs to change it's state of matter (the more energy a substance has the higher it's temperature)
Is energy released during melting?
No. When a substance melts it absorbs energy.
