Energy Transfers and Transformations

Front

What is energy transfer?

Back

Energy transfer is the process of moving energy from one place to another, such as from a hot object to a cooler one.

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

How do you calculate heat energy?

Back

Heat energy (Q) can be calculated using the formula Q = mass (m) × specific heat (c) × change in temperature (ΔT).

Front

What is convection?

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 an example of convection?

Back

Boiling water is a common example of convection, where hot water rises and cooler water sinks.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat.

Front

What is an example of radiation?

Back

Microwave cooking food is an example of radiation, where microwaves transfer energy to heat the food.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height.

At which position does a roller coaster cart have the most gravitational potential energy?

Back

The roller coaster cart has the most gravitational potential energy at the highest point, often referred to as position W.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.
