A rigid, sealed container of gas is heated, causing its temperature to rise. This leads to an increase in the pressure exerted by the gas.
Which statement explains this increase in pressure?
The gas particles collide with the walls of the container more frequently and with greater force.
The forces of attraction between the gas particles and the walls of the container increase.
The individually-sized gas particles expand, causing more frequent collisions between particles.
The gas particles transfer less momentum to the walls during each collision.
