Pressure is given by the equation P = F/A, where F is force and A is the area it's applied over. For a solid or liquid, you can increase pressure just by pushing harder on it.
For a gas, pressure is approximately given by P = (n*R*T)/V, where n is how much gas you have in moles, T is the temperature in kelvin, V is the volume of the container, and R is a constant. So to increase pressure, either increase the amount of gas, increase the temperature, or decrease the volume of the container.

How can pressure be increased or decreased?
Increase pressure: decrease volume, increase temperature, increase moles of substance. Decrease pressure: do the reverse
In divergent nozzle pressure will increase or decrease?
If the flow is subsonic the pressure will increase, if however it is supersonic the pressure will decrease.
As the altitude increases does the barometric pressure increase or decrease?
Decrease
An increase in evaporation is caused by?
- an increase of the temperature - a decrease of the pressure
What 2 thing increase the rate of condensation?
Decrease in temperature and increase in pressure.
Do skis increase or decrease pressure?
they decrease pressure

Does air pressure increase or decrease as you go higher?
decrease
As the altitude increases does the barometric pressure increase or decrease?
Decrease
How can you increase the solubility of a gaseous solute?
Decrease the temperature, if aqueous. Increase the pressure.
When you exert force on a fluid in a closed container does the pressure increase decrease or remain constant?
The pressure increases.
Does pressure increase or decrease as it goes deeper in the earth?
Increase.
Will increase the volume of the gas?
An increase of the temperature or a decrease of the pressure.
An increase in evaporation is caused by?
- an increase of the temperature - a decrease of the pressure
As the temperature of a fixed volume of a gas increases the pressure will?
decrease
How will a pressure increase affect a gaseous system?
According to Boyle's Law of Pressure-Volume Relationship, an increase in the pressure of a gas will decrease it's volume. And according to Charles's Law of Temperature-Pressure Relationship, an increase in pressure causes an increase in temperature.
