BP- 159 What will happen to the gas molecules when the container is heated? They will become denser. They will expand. They will move further apart. They will move more quickly. 15 The diagram shows a cylinder made of insulating material with a movable piston at one end. The piston can be pushed or pulled without the gas leaking out. das Which statement about the gas when the piston is moving is not correct? The density of the gas decreases as the piston is pulled outwards. The mass of the gas in the piston remains unchanged. The pressure of the gas decreases as the piston is pulled outwards. The temperature increases as the piston is pushed gently inwards. 16 When a hand is placed on a metal surface and a wooden surface at room temperature, it feels colder on the metal surface than on th6 wooden surface.
