PS - Unit 8: Flow of Energy

Front

What is specific heat?

Back

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

Front

Which material has the highest specific heat?

Back

Water has one of the highest specific heats among common substances.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is conduction?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as heat from the sun.

Front

Why does hot air rise?

Back

Hot air is less dense than cold air, causing it to rise.

Front

What happens to water at its boiling point?

Back

At its boiling point, water begins to evaporate and turn into gas.
