Front

What energy conversion occurs in a clothes dryer?

Back

A clothes dryer converts electrical energy to heat and mechanical energy.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.

Front

What happens to chemical energy in natural gas when heating water in a kettle?

Back

Some of the chemical energy in natural gas transforms into thermal energy, heating the water.

Front

What type of heat transfer is primarily responsible for the rising of a hot air balloon?

Back

Convection is the primary type of heat transfer that causes a hot air balloon to rise.

Front

Define igneous rock.

Back

Igneous rock is formed from the cooling and solidification of magma or lava.

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 particles in a substance.

Front

Explain convection in the context of heat transfer.

Back

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

Front

What is the role of mechanical energy in a clothes dryer?

Back

Mechanical energy helps to tumble and move the clothes, aiding in the drying process.

Front

What is the difference between conduction and convection?

Back

Conduction is the transfer of heat through direct contact, while convection involves the movement of fluids.
