Using the kinetic theory explain why the pressure of a gas increases when the temperature increases?

When the temperature of a gas increases, the Kinetic Energy of the particles increases. This means that they move faster and apply a greater force when they collide with the walls of the container. As pressure is the force per unit area on the container, the pressure increases. This is Gay-Lussac's "Pressure Temperature" Law: "P = kT".

How can pressure change a liquid into a solid?
Liquid changes to gas when pressure is reduced and temperature is increased. When pressure on liquid is reduced, the inter molecular space increases and temperature increases the kinetic energy of the atoms. This changes liquid to gaseous state
What happens to the kinetic energy when an object moves faster?
it gets greater because the greater the mass the greater kinetic energy
Does the concept of temperature apply to a single molecule?
Concept of temperature in single molecules could be explain through statistical thermodynamics and measure the temperature in term of kinetic energy of the molecules. Forclassical thermodynamics, the temperature is macroscopic properties andcan't be explain or describe in the classical scope.
What determines speed?
Temperature is a major determinant of molecular velocity. By applying heat to a system molecular velocity increases, as does pressure and kinetic energy. The two physical and chemistry equations of the Ideal Gas Law and calculating kinetic energy through mass and velocity illustrate this relationship mathematically.
What happen to air particles as they heat up and cool down?
Depends on the container of the "air particles" and what you mean by "what happens." If it is inside a container that can not expand, then the pressure increases. If it is inside a container that can expand (or is just atmospheric air) then the volume increases. (Pressure * Volume = n * R * change in temperature) On the atomic level, the atoms or molecules (depending on the gas) begin to move more quickly as their kinetic energy increases.
How does a substances temperature change when the average kinetic energy of its particles increases When it decreases?
It decreases in relation to lower temperature.
What energy increases when temperature increases in a thermometer?
Kinetic
What increases when the average Kinetic energy of the particles in a material increases?
The average kinetic energy of colliding particles can be increased by increasing temperature.
What happenes to tire pressure in hot weather?
pressure increases with temperature, per the universal gas law This is true, but a better way of putting it is that temperature is the measure of the average kinetic energy of a substance (in this case particles of a gas) and so as temperature increases, the kinetic energy increases because the two things are directly proportional. As the energy increases, there are more collisions between the gas particles and the inside of the tire, making the pressure increase, which is also why you should check tire pressure before a trip, not during it.
How does a substances temperature change when the average kinetic energy of it's particles increases?
As the average kinetic energy of a substance increases, the temperature will increase.
What happens to kinetic energy of gas particles as temperature decreases at a constant pressure?
kinetic energy increases with the increase in temperature is a postulate in kinetic molecular theory of matter.if the pressure is kept constant when temperature decreases the kinetic energy of the molecules decreases resulting in decrease in the volume of the gas. Charle's Law state's that For a given mass of dry gas at constant pressure ,volume is directionally proportional to temperature ie V~T
What happens to the kinetic energy when temperature is changed?
When the temperature is increased the kinetic energy increases, and when it is decreased the kinetic energy decreases.
How does a substance 's temperature change when the average kinetic energy of it's particle increases?
As the average kinetic energy of a substance increases, the temperature will increase.

Is it true that when increases the average kinetic energy of the particles decrease?
No. It is the opposite. When temperature increases, the average kinetic energy of the particles also increases.
Does the temperature change if the average kinetic energy of a substance changes?
When Ave KE increases temperature increases.
Is it true that temperature increases the average kinetic energy increases?
Yes, that is true.
