Define work in physics.
Show answer
The transfer of energy by a force.
What happens to the internal energy of a gas when work is done on it?
Show answer
It increases, which can cause the temperature of the gas to rise.
Doing work on a gas increases the ? of the gas.
Show answer
internal energy
Why does the air in a bicycle pump get warmer when it is compressed?
Show answer
Pushing the piston does work on the enclosed gas, increasing its internal energy and so raising its temperature.
Which everyday device shows that doing work on an enclosed gas raises its temperature?
Show answer
A bicycle pump — the pump warms up as the air inside is compressed.
Why is ionising radiation described as both hazardous and useful?
Show answer
It can damage living tissue, but radioactive materials are widely used in medicine, industry, agriculture and electricity generation.
Rules for radiological protection were first introduced in the ?.
Show answer
1930s
What harm came to early researchers into radioactivity?
Show answer
They suffered from their exposure to ionising radiation, before protection rules existed.
Name one field in which radioactive materials are widely used today.
Show answer
Medicine (also industry, agriculture, or electrical power generation).
