Heat and Thermal Energy 2023

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of particles in a fluid (liquid or gas) from one place to another.

Front

What happens to the temperature of a material with low specific heat when it absorbs energy?

Back

The temperature of a material with low specific heat rises more significantly when it absorbs a given amount of energy.

Front

What does a high specific heat indicate about a material?

Back

A high specific heat means that the material requires more energy to change its temperature.

Front

What is the transfer of thermal energy from a warmer object to a cooler object called?

Back

This process is called heat transfer.

Front

What is the primary method of heat transfer in fluids?

Back

Convection is the primary method of heat transfer in fluids.

Front

Define conduction.

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is radiation in the context of thermal energy?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, such as infrared radiation.

Front

How does temperature relate to thermal energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance, indicating its thermal energy.

Front

What is specific heat?

Back

Specific heat is the amount of energy required to raise the temperature of one gram of a substance by one degree Celsius.

Front

Why do materials with high specific heat change temperature slowly?

Back

Materials with high specific heat require more energy to change their temperature, so they heat up and cool down more slowly.
