Answer 2

I can answer your questions in detail. Here is what I found:

1) The pressure of a solid body is calculated by the formula: b) p = F/S, where p is the pressure, F is the force, and S is the area of the surface . This formula means that the pressure is proportional to the force and inversely proportional to the area. 2) The pressure of a body on a support will increase if: a) reduce the area of the support . This is because the smaller the area, the larger the pressure for the same force, according to the formula above. 3) When the temperature increases, the pressure of a gas will: a) increase . This is because the gas molecules will move faster and collide more frequently and forcefully with the walls of the container, exerting more pressure. The pressure of a gas is proportional to its temperature, if the volume and the mass of the gas are constant.
