Conduction & Convection

Front

What is the primary difference between conduction and convection?

Back

Conduction is the transfer of heat through direct contact between materials, while convection is the transfer of heat in a fluid through currents.

Define conduction.

Back

Conduction is the process of heat transfer through direct contact of particles in a solid.

Front

Define convection.

Back

Convection is the transfer of heat in a fluid (liquid or gas) through the movement of currents.

Front

What are conductors?

Back

Conductors are materials that easily transfer heat, such as metals.

Front

What happens to fluids when they are heated?

Back

As fluids are heated, they become less dense and rise.

Front

What is an example of convection in everyday life?

Back

An example of convection is the operation of a lava lamp.

Front

What is the role of density in convection?

Back

Density differences in fluids drive convection currents; warmer, less dense fluid rises while cooler, denser fluid sinks.

Front

What type of materials are considered insulators?

Back

Insulators are materials that do not easily transfer heat, such as wood, plastic, and rubber.

Front

How does convection occur in the atmosphere?

Back

Convection in the atmosphere occurs when warm air rises, cools, and then sinks, creating wind patterns.

Front

What is the significance of convection in weather systems?

Back

Convection plays a crucial role in weather systems by helping to distribute heat and moisture in the atmosphere.
