As a student of class 9, I think these answers are enough. Examples where decrease in pressure necessary
1 conversion of water into water vapour
2 conversion of ice into water
3 Melting of iron
Examples where increase in pressure necessary
1 conversion of water vapour into water
2 conversion of water into ice
3 solidifying gold dissolved in aqua regia

⚡ As per you, i think this is a physics question. So, let us have a detailed answer to this question on the basis of concept of physical topics.
⚡ Here, we will include pressure as a physical factor influencing a specific factor.

❄❄❄❄ ANSWER ❄❄❄❄
==================================
*⃣ REDUCING OF PRESSURE *⃣
1] Pressure should decrease or reduce at higher altitudes due to the extreme low density of gas molecules of there.
2] Fluid Pressure should be reduced when it will be contained in any beakers ir containers. If a huge amount of pressure gets exerted by that fluid on the walls of the container then the walls may get broken and the fluid escapes from that container
3] Heavy trucks having eighteen tyres reduces or decreases the pressure on the ground because an increase in the number of tyres causes an increase in the area of contact, thereby reducing the pressure.
*⃣ INCREASING THE PRESSURE *⃣
1] Pressure should increase at lower altitudes specially the pressure (atmospheric pressure) is maximum at sea level. At lower altitudes, air density is more and hence pressure should have to be increased.
2] Water tanks when moving on ground will apply a huge pressure on the ground and thus the pressure has to be increased.
3] While cutting fruits and vegetables we use knife which have a sharpened edge having a less area of contact. Thus, the knife will apply a great pressure on the fruits and vegetables to cut them. Thus the pressure has to be increased.
