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.

What are the three main types of heat transfer?

Back

The three main types of heat transfer are conduction, convection, and radiation.

Front

Define conduction in the context of heat transfer.

Back

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

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.

Explain radiation as a method of heat transfer.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, and does not require a medium to travel.

What is the relationship between temperature and density in solids, liquids, and gases?

Back

In general, as temperature increases, density decreases for most substances, except for water, which is denser at 4°C.

How does the density of solids compare to liquids and gases?

Back

Solids are generally the most dense form of matter, followed by liquids, with gases being the least dense.

Front

What happens to the temperature of an object when it absorbs heat?

Back

When an object absorbs heat, its temperature increases as the thermal energy increases.

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

How does the sun heat the Earth?

Back

The sun heats the Earth primarily through radiation, as solar energy travels through the vacuum of space.
