Thermal energy is the same as

• Temperature

• The same as total kinetic energy

• hot or cold energy of a system

• the heating system of the school

A cup of soup and a bowl of soup both have a temperature of 75 degrees Celsius

• The cup has more thermal energy

• They have the same thermal energy

• The bowl has more thermal energy

• There is not thermal energy

What has the biggest impact on the thermal energy of a sample?

• The temperature

• The type of materiel

• Its location

• The number of molecules in the sample

When a bowl of soup cools of to the same temperature as the room it has reached...

• equilibrium

• cold energy

• heat energy

• a temperature that is not able to be eaten

The greater the mass of an object the

• lower the kinetic energy

• greater the kinetic energy

• lower the temperature

• greater the size of the object

In a system the total kinetic energy is

• made up of all of the molecules minus the difference in temperature

• the thermal energy divided by 2

• found by subtracting the differences in energy

• evenly divided among all the molecules in a system

When energy is transferred in a system...

• only some molecules are affected

• the energy is divided among all of the molecules

• some energy is created and some is destroyed

• the system will lose energy

As energy transfers in a system

• energy is created and destroyed

• energy increases in one part and decreases in the other

• it will always get colder

• it was always get warmer
