Q

how is absolute zero obtained

A

1) As we increase the temperature of an object, we give kinetic energy to its particles, making them move around more.
2) The hotter an object gets, the more its particles move around.
3) Therefore the colder an object gets, the less its particles move around.

4) So there must be a temperature where all the particles completely stop moving - they have zero kinetic energy.
This temperature is called absolute zero.

Q

what is absolute zero

A

absolute zero is the temperature at which all particles stop moving as they have no kinetic energy.
