Thermal Energy Quiz

What is thermal energy?

• The sum of potential and kinetic energy of the particles in an object

• The total amount of heat in an object

• The temperature at which an object freezes

• The light energy emitted by an object

What happens to thermal energy as the mass of an object increases?

• It decreases

• It remains constant

• It increases

• It fluctuates unpredictably

What happens to thermal energy as the temperature increases?

• It decreases

• It remains constant

• It increases

• It fluctuates unpredictably

What does temperature measure?

• The total potential energy of particles in an object

• The average kinetic energy of particles in an object

• The total mass of particles in an object

• The speed of light particles in an object

What is the relationship between temperature and the movement of particles in an object?

• The higher the temperature, the slower the particles move

• The lower the temperature, the faster the particles move

• The higher the temperature, the faster the particles move

• Temperature has no effect on the movement of particles

What is the direction of thermal energy transfer?

• From lower temperature objects to higher temperature objects

• From higher temperature objects to lower temperature objects

• From the object with less mass to the object with more mass

• Randomly between objects regardless of temperature

What is heat defined as in the context of thermal energy?

• The amount of energy contained within an object

• The light emitted by an object

• The transfer of energy from one object to another

• The temperature difference between two objects

How is heat measured?

• Celsius

• Fahrenheit

• Joules

• Kelvin

What does it mean when you feel cold according to the concept of thermal energy transfer?

• It means that cold is being transferred to you.

• It means that heat is being generated within your body.

• It means that you are feeling the absence of heat.

• It means that the temperature around you is below freezing.

When heat flows into an object, what is the sign of the change in heat?

• The change in heat is 0

• The change in heat is +

• The change in heat is -

• The change in heat is undefined
