When there is not enough ______________, change in a substance cannot occur.
Energy
If two objects have different temperatures, in which direction will heat move?
High temperature to low temperature.
Energy that is shifted from warmer to cooler temperatures between two substances.
Heat
The total thermal energy of a system depends jointly on the temperature, total number of ______________ in the system, and the state of the material.
Atoms
If two objects have different temperatures, how long will the direction of heat move between the two objects.
The heat will flow until the temperature of the two objects is the same.
Determined from the sum of potential and kinetic energy in a substance.
Total internal energy.
The total thermal energy of a system depends jointly on the temperature, total number of atoms in the system, and the ______________ of the material.
State
How are thermal energy and temperature related in a substance?
As thermal energy increases in a substance, temperature increases as well.
