Heat, Temperature, and Thermal Energy

Heat is

• the  movement of thermal energy from a warmer to cooler object
• moving particles
• the average kinetic energy of the particles that are in a substance
• the  amount of matter in an object

The sum of the kinetic energy and the potential energy of the particles that make up something is

• temperature
• heat
• thermal energy
• matter

The average kinetic energy of the particles that make up a substance is 

• temperature
• heat
• kinetic energy
• conduction

Heat is thermal energy transferred from one object to another becuase of a difference in

• mass
• volume
• temperature
• potential energy

When the temperature increases what else increases?

• potential energy
• kinetic energy
• gravitational potential energy
• total energy

The thermal energy of an object is

• its potential energy
• its average kinetic energy
• its potential energy minus its kinetic energy
• its kinetic energy plus its potential energy

Water is heated on a stove, which kind of energy is transferred?

• gravitational energy
• kinetic energy
• potential energy
• thermal energy

A hot iron is turned off and cools down to room temperature.  The iron cools because....

• the iron does not hold heat very well
• the room transfers cold energy to the iron
• heat energy is transferred from the warm iron to the cooler room
• the thermal energy is destroyed during an interaction with the room

Heat always moves from...

• warm area to cold areas.

• cold areas to warm areas.

• evenly from warm to cold and cold to warm.

Thermal energy stops moving when the objects have the same temperature.

• True
• False
