Question

A gas is most likely to exist at which of the following conditions?

High temperatures and high pressures
High temperatures and low pressures
Low temperatures and high pressures
Low temperatures and low pressures

Answer 1

High temperatures and low pressure. Low pressure, most of the time, is correlated with high temperatures.

Hope this helps!

Answer 2

Answer: Option (b) is the correct answer.

Step-by-step explanation:

When we heat a solid substance at high temperature then it changes into liquid state and then into gaseous state.

For example, when water is heated above 100 degree celsius then it changes into vapors.

When low pressure is provided to a gas then its molecules are able to move easily from one place to another.

Therefore, a gas is most likely to exist at high temperature and low pressure.
