Physics P3
Gas pressure
Increased gas temp, increases the kinetic energy and particle speed. This increases the rate of collisions of the particles with the container walls.
More collisions means more force on the container over a certain area and therefore a greater pressure.
-
The particles in a gas collide with each other and the walls of their container without losing any of their kinetic energy
Temperature
-
The greater the temperature, the greater the kinetic energy and therefore the speed of the particles
Particles in solids, liquids and gases all have kinetic energy because they are always moving.
Specific latent heat
The amount of energy required to change the state of 1kg of the substance with no change in temperature is the specific latent heat of a substance.
-
When a change of state occurs, any heat energy supplied breaks the bonds between molecules. No change in temperature occurs during this time.
Specific heat capacity
-
The specific heat capacity of a substance is the amount of energy required to raise the temperature of 1kg of a material by 1℃
-
Internal energy
The total kinetic energy and potential energy of all the particles in the system is the internal energy of a system.
Potential energy
Particles in solids, liquids and gases have potential energy because their motion keeps them separated. This opposes the forces trying to pull them together. Gas particles have the most potential energy because they are the furthest apart.
