When gases move around, they are colliding with the walls of their container and with each other. When they collide, the exert a force, creating pressure.
If you heat a gas, the particles have more energy and so they move faster, this means that they collide more often and with greater force, so the pressure is increased.
If you squish a gas, the particles are closer together, so they collide more often, so pressure is increased.
