What is thermal energy?
It is the internal energy of an object due to temperature.
1 of 10
When does energy between two object transfer?
1) When one object does work on the other 2) Through the heating because of temperature difference between 2 objects.
2 of 10
What is the first law of thermodynamics?
The change of internal energy of the object = the total energy due to the work done and heating.
3 of 10
What is internal energy?
The sum of the random distribution of the kinetic and potential energies of its molecules.
4 of 10
What are the properties of a solid?
1) They vibrate randomly about fixed positions. 2) The higher the temperature of the solid, the more the molecules vibrate.
5 of 10
What are the properties of a liquid?
1) The forces between the molecules are not strong enough to hold the molecules in fixed positions. 2) The higher the temperature of a liquid the faster its molecules move the energy supplied to a liquid.
6 of 10
What is thermal equilibrium?
It is when no overall heat transfers occurs between two objects at the same temperature.
7 of 10
What is absolute zero?
It is the lowest possible temperature, the temperature at which an object has minimum internal energy.
8 of 10
What is heat capacity?
It is the energy needed to raise the temperature by 1C and by 1kg.
9 of 10
What is the formula for heat capacity using electrical methods?
c=IVT/M*(change in Temperature)
