Temperature, Heat, & Specific Heat

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the individual particles in an object.

Front

How does the kinetic energy of molecules in a gas compare to that in a solid?

Back

Molecules in a gas move faster than those in a solid.

Front

What happens to the particles of a substance when heat is added?

Back

The particles speed up.

Front

What happens to the particles of a substance when heat is removed?

Back

The particles slow down.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in an object.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases).

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature measures the average kinetic energy of particles.

Front

What occurs during the process of evaporation?

Back

During evaporation, particles at the surface of a liquid gain enough energy to become gas.
