heat thermal energy first law of thermal energy

Work is a transfer of

• energy.

• force.

• mass.

• motion.

The energy of motion is called

• kinetic energy.

• potential energy.

• thermal energy.

• work.

Which of the following increases when an object becomes warmer?

• chemical energy

• elastic potential energy

• nuclear energy

• thermal energy

The total potential and kinetic energy of all the microscopic particles in an object make up its

• chemical energy.

• electric energy.

• nuclear energy.

• thermal energy.

Walking converts what type of energy into mechanical energy?

• chemical

• electromagnetic

• nuclear

• thermal

Heat is the transfer of thermal energy from one object to another because of a difference in

• specific heat

• phase

• temperature

• waste heat

What property of an object is related to the average kinetic energy of the particles in that object?

• specific heat

• mass

• conducitvity

• temperature

As the temperature of an object rises, so does the

• kinetic energy of the object.

• mass of the object.

• thermal energy of the object.

• potential energy of the object.

Thermal energy depends on an object’s

• mass.

• phase(solid, liquid, gas)

• temperature

• all of the above

In the formula Q=m x c x ∆T, which quantity represents the specific heat?

• c

• m

• Q

• ∆T
