Science Vocabulary Review TE 4

Front

What is stainless steel?

Back

A strong, durable metal that is resistant to rust and corrosion, commonly used in products like the Stanley cup.

Front

What is vacuum insulation?

Back

A method of insulating that prevents heat transfer by creating a vacuum between two layers, commonly used in thermoses.

Front

What happens to molecules when they gain thermal energy?

Back

They vibrate faster, which can lead to an increase in temperature.

Front

What is thermal energy?

Back

The energy that comes from the temperature of matter; it is the total energy of all the particles in an object.

Front

What is the purpose of insulation?

Back

To reduce the transfer of heat between objects or environments.

Front

What does it mean for a material to be porous?

Back

A material that has tiny holes or spaces that allow air or liquid to pass through.

Front

What is conduction?

Back

The process by which heat energy is transferred through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

The transfer of energy through electromagnetic waves, such as heat from the sun.

Front

What is the role of air in insulation?

Back

Air can act as an insulator because it is a poor conductor of heat.
