Question

What gives rise pressure to on the gas?

Answer 1

Understanding the concept:

• Pressure is defined as the amount of force applied over a unit area per unit of time
• Mathematically, P=F/A
• The force upon the area equals the pressure.
• There are two ways to increase pressure using the equation:
• increase the rate of force applied or reduce the surface over which it has been applied.

In this case, generally, the Ideal Gas Law came into place:

• Real gases act like ideal gases at low (normal) pressures, thus you may use the Gas Laws to figure out how to raise a system's pressure.
• The Ideal Gas Law states; that P = nRT/V
• Where P denotes pressure, V denotes volume, n denotes the number of moles in a gas, R denotes Boltzmann's constant value, and T denotes temperature.
• If you solve for P, we get:
• P = (nRT)/V

Thus there are three ways to increase the pressure of gas;

• Increase the temperature of the gas. This is represented by the “T”.
• Increase the amount of gas. This is represented by the “n”.
• Decrease the volume of the gas. This is the "V" in the equation.
