Q5.
The drawing shows a cylinder of butane. The butane is under pressure in the cylinder.
Most of the butane in the cylinder is liquid, but some is a gas.
butane gas
BUTANE
(a)
Tick the two correct statements about the molecules of butane gas in the cylinder.
The molecules of gas are:
closer together than those in the liquid;
further apart than those in the liquid;
the same distance apart as those in the liquid;
bigger than those in the liquid;
smaller than those in the liquid;
the same size as those in the liquid;
The gas molecules exert a pressure on the inside of the cylinder.
How do the moving molecules cause this pressure?

Answer 1

The two correct statements about the molecules of butane gas in the cylinder are:

- Further apart than those in the liquid

- The gas molecules exert a pressure on the inside of the cylinder.

The moving molecules cause this pressure because they collide with the walls of the cylinder and exert a force on them, creating a pressure. More collisions per unit time mean a higher pressure.
