In a first attempt (please note that it is only an approximation) you can consider the law of ideal gases which says
pV = nRT
where p is the pressure, V the volume, nthe number of moles, R is a constant and T the temperature.
So you can see that
T = p · V/(nR)
If V/(nR) is a constant, you can see immediately that the higher the pressure the higher the temperature (they are proportional magnitudes).
If you want a deeper understand, you have to know that the kinetic theory of pressure establishes a direct relationship between pressure and speed (in an informal way, pressure is a consequence of collisions between gas particles and the walls in which they are confined). So the higher the speed the higher the pressure.
In addition to this, the speed is related to the temperature across the virial theorem, which establishes that T is proportional to the speed squared.
So, as we showed in the firsts lines, an increment in the pressure cause an increment in the speed and, consequently, an increment in the temperature.

What happens the density of a gas as it is compressed?
The atoms or molecules of a gas will increase in thermal energy when the gas is compressed. The kinetic energy of those atoms or molecules will increase as they are forced closer together in compression, and the temperature of the gas will increase.
What happens to a gas's thermal energy as that gas's temperature increases?
It increases.
How the temperature of gas is increased and decreased?
When the speed of a gas molecules increases, the gas molecules hit their container more often. The more frequently the gas impacts the container walls, the higher the pressure. So, as temperature increases, the pressure also increases.
What happens to its volume when the temperature of a gas increases at constant pressure?
The volume increases.
What happens to strength when temperature of solid metal increases?
The pressure at which it yields is reduced as the temperature increases
What happens to the temperature of a gas that is squeezed or compressed?
If you compress a gas the temperature increases
What would be the kinetic energy of particles of gas when it compressed in a cylinder?
When a gas is compressed, its temperature tends to increase. That means that the average kinetic energy per particle also increases.
When the pressure of a gas increases at constant temperature its volume?
Temperature increases as pressure increases.
What happen to air when it is compressed?
When air is compressed temperature increases because of the collission and vibration of molecules
How is pressure affected when a gas is compressed?
When a gas is compressed, so volume is decreased, the pressure increases. P=1/V
How does the temperature of gas change when it is compressed when it expands?
Gas is a loosely bound group of molecules that have changed phase from solid to liquid to gas through an increase in thermal energy. Once it has reached the gas phase, heating gas can increase its temperature because the energy will not go into the potential energy of a phase change, but instead the kinetic energy of phase change.
What are the impacts of temperature on gas?
The impacts of temperature on gas are manifold. Increase in temperature increases the gas pressure by increasing its volume. It increases the solubility of gas and vice-verse. The viscosity of gas also increases with increase in temperature.
What happens the density of a gas as it is compressed?
The atoms or molecules of a gas will increase in thermal energy when the gas is compressed. The kinetic energy of those atoms or molecules will increase as they are forced closer together in compression, and the temperature of the gas will increase.
What happens to a gas's thermal energy as that gas's temperature increases?
It increases.
When the temperature of of gas increases at constant pressure its?
As pressure increases, if temperature is constant, the gas will decrease in volume.
What is the density of gas?
Asking "what is the density of a gas" is just like asking "what is the density of a liquid or solid". This entirely depends on what gas it is and only in the case of gases, what temperature and pressure it is at too.
What happens when a gas is compressed in a closed container?
The particles get closer together and their temperature increases.
