because in hot air the particles move faster and as we know that kinetic energy increases with increase in temperature so it become lighter . and in cold air the particle come too closer and hence become heavier

Hot air rises because when you heat air (or any other gas for that matter) , it expands. when the air expands, it became less dense than the air around it
