What happens to the heat in a glass of tea when ice is added?

Back

The heat moves from the ice tea and into the ice, cooling down the ice tea.

Front

What safety equipment should be used when heating a beaker of water?

Front

What does a graph showing the speed of a steel ball down a ramp indicate?

Front

What does the graph indicate about the speed of the steel ball?

Back

Front

Define conduction in terms of heat transfer.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

Explain the principle of buoyancy.

Back

Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in it.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

Define gravitational force.

Back

Gravitational force is the attraction between two masses, such as the Earth and an object.
