Question

explain the effect on matter when 1) pressure is changed 2) temperature is changed​

Answer 1

Explanation:

When we apply pressure and reduce temperature the gases can be converted into liquids i.e., gases will be liquefied. The process of conversion of a gas into a liquid by increasing pressure or decreasing temperature is called liquefication.

Answer 2

Answer:

Both temperature and pressure can be measured, and state changes can be observed. When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).
