Chemistry: Review #3

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

How many forms of mechanical energy are there?

Back

There are two forms of mechanical energy: potential energy and kinetic energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in a substance.

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat, without the need for a medium.

Front

What substance has a high heat capacity?

Back

Water has a high heat capacity, meaning it can absorb a lot of heat before its temperature rises significantly.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is a metal spoon getting hot when placed in a hot liquid.

Front

What is an example of convection in everyday life?

Back

An example of convection is warm air rising and cool air sinking, creating a circulation pattern in a room.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling warmth from the sun on your skin.
