Unit 2 Energy-CP

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released during a chemical reaction, often in the form of heat or light.

Front

What type of energy is produced when fuel is burned?

Back

Thermal energy is produced when fuel is burned, as it generates heat.

Front

What is convection?

Back

Convection is the method of heat transfer that involves the movement of warm air rising and cool air sinking, creating a circulation pattern.

Front

What is the best insulator for a cooking vessel?

Back

Rubber is considered the best insulator for a cooking vessel because it does not conduct heat well.

Front

What type of energy do solar panels convert?

Back

Solar panels convert light energy into electrical energy.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, which can travel through space. It includes visible light, infrared, and ultraviolet radiation.

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 conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally (like solar and wind), while non-renewable sources (like coal and oil) are finite and will eventually run out.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object, related to its motion and position.
