Front

What happens to an ice cube when thermal energy is applied?

Back

It melts.

Front

What does the Greek prefix 'atmo-' mean?

Back

Vapor.

Front

What type of heat transfer is demonstrated when baby chickens are kept warm from heat lamps?

Back

Radiation.

Front

What is the relationship between the movement of molecules and temperature?

Back

The faster molecules move, the higher the temperature.

Front

What type of thermal energy transfer is associated with the movement of fluids?

Back

Convection.

Front

Define thermal energy.

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

What is conduction in terms of heat transfer?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

Explain the process of convection.

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) due to differences in temperature and density.

Front

What is the significance of the term 'specific heat capacity'?

Back

Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

Front

How does radiation differ from conduction and convection?

Back

Radiation transfers heat through electromagnetic waves and does not require a medium, while conduction and convection require matter.
