A sealed cylinder that contains gas is placed in direct sunlight. After some time, the cylinder bursts. How can this be explained in terms of the motion and behaviour of the gas particles?

  • AEach particle gets bigger and they collide with each other more often.
  • BEach particle gets bigger and they collide harder with the cylinder.
  • CThe particles gain kinetic energy and hit the cylinder harder and more often.
  • DThe particles lose kinetic energy and they hit the cylinder harder and more often.
