Increasing
Explanation:
We can change gas to liquid by decreasing the temperature and increasing the pressure.
- Temperature is the degree of hotness or coldness of a body.
- It is a function of how much heat it has absorbed or lost.
- Heat causes the thermal energy of a system to increase and the particles becomes randomized.
- Pressure is the force per unit area of particles.
- If we decrease the temperature of gases, they have less kinetic energy and entropy reduces.
- The will not be random.
- Further increasing their pressure will bring them together and make them flow like liquid.
- This phase change is often called condensation.
