Energy - Task 1: Compare Thermal Energy and Temperature

A measurement of the average amount of kinetic energy of the particles in a sample of matter.

• Temperature

• Energy

• Potential energy

• Heat

The transfer of thermal energy between objects

• Kinetic energy

• Temperature

• Heat

• Potential energy

During summer the ground temperature is 50°C. If you place a piece of ice that has a temperature of –6°C.

Which statement best explains what happens?

• Heat transfers coldness from the ice to the ground.

• Thermal energy transfers heat from the ground to the ice.

• Thermal energy transfers coldness from the ground to the ice.

• Heat transfers thermal energy from the ground to the ice.

A snowball is made up of frozen water, which means its temperature is at or below 0°C. A person's hand is usually at normal body temperature, about 37°C.

A person holds a snowball in his hand. Which photo shows the direction of thermal energy transfer?

• 
• 
• 
• 

The photo shows a person holding a frozen yogurt.

Which statement best explains why the yogurt is melting?

• The temperature of the person's hand is higher than the temperature of the yogurt.

• Heat is transferring thermal energy from the yogurt to the person's hand.

• The temperature of the person's hand is lower than the temperature of the yogurt.

• The yogurt has more heat than the person's hand.

The movement of thermal energy from a warmer object to a cooler object is called:

• heat
• temperature
• motion
• momentum

Heat transfer occurs:

• in many directions
• both from warm objects to colder ones and from cold objects to warmer ones
• only from warm objects to colder ones
• only from cold objects to warmer ones

Energy that moves particles of matter is 

• temperature
• thermal energy
• heat
• friction

The temperature of a substance increases as___.

• the substance expands
• the average kinetic energy of its particles increases
• the substance's volume increases
• the substance's mass increases

Thermal energy always moves from warmer substances to cooler substances.

• True

• False
