Cylinder *A *
has a movable
piston and contains hydrogen gas. An identical cylinder,
*B,*
contains methane gas. The diagram below represents these
cylinders and the conditions of pressure, volume, and
temperature of the gas in each cylinder.

60 Compare the total number of gas
molecules in cylinder *A
*to the total number of gas molecules in
cylinder *B. [1]*

**Highlight box to reveal answer**

The number of gas molecules in
cylinder *A *is the same as the number of
gas molecules in cylinder 13. |

61 State a change in temperature and a
change in pressure that will cause the gas in cylinder
*A *to behave more like an ideal gas. [1]

**Highlight box to reveal answer**

Temperate: higher
Pressure: lower
Temperature: above 293 K
Pressure: below 1.2 atm |

62 In the space *in your answer
booklet, *show a numerical setup for calculating the
volume of the gas in cylinder B at STP. [1]

(1.2atm)(1.25L)/293K=(1.0 atm)(V_{2})/273K
or (273)(1.2)(1.25)/293 |
