An ideal gas is a theoretical gas that follows the ideal gas law, which states that the pressure, volume, and temperature of a gas are directly proportional to each other.
In an ideal gas, an increase in pressure will result in a decrease in volume, assuming the temperature remains constant. This is known as Boyle's Law.
According to Charles' Law, an increase in pressure will also cause an increase in temperature, assuming the volume remains constant.
No, an ideal gas does not have intermolecular forces, so it cannot change states. It will only change its physical properties, such as volume and temperature, when pressure is altered.
The pressure of an ideal gas is directly proportional to its kinetic energy. As the gas molecules move faster, they collide more frequently with the walls of the container, resulting in a higher pressure.
