What is convection?

Back

Convection is the transfer of heat through a fluid (liquid or gas) caused by the movement of the fluid itself. Hot fluid expands, becomes less dense, and rises, while cooler fluid becomes denser and sinks.

Why do we wear sweaters in cold weather?

Back

We wear sweaters in cold weather to reduce heat loss from our bodies, helping to maintain our body temperature.

What happens to water in a freezer as it turns into ice?

Back

As water in a freezer turns into ice, the surrounding air in the freezer absorbs heat from the water, causing the water to freeze.

What effect does supplying more heat to a system have on particles?

Back

Supplying more heat to a system causes the particles to speed up, increasing their kinetic energy.

What is the transfer of thermal energy through flow called?

Back

The transfer of thermal energy through flow is called convection.

Front

What is conduction?

Back

Conduction is the transfer of heat through a solid material without the movement of the material itself, typically occurring through direct contact between particles.

What is radiation in terms 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 through.

How does temperature affect the density of a substance?

Back

As temperature increases, the density of a substance generally decreases because the particles move apart, making the substance less dense.

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, resulting in no net heat transfer between them.

Front

What is the role of a heat sink?

Back

A heat sink is a device or substance that absorbs and dissipates heat from another object, helping to regulate temperature.
