Explanation / Answer

1. With temperature as constant, as pressure of gas is increased, volume would decrease, . If pressure is held constant, as the temperature is increased, the volume would increase.

decrease,increase

2. The height measured is 414 mm

So pressure in kPa = 414 mm x 0.13332 = 55.195 kPa

3. the graphs which would a straight line when plotted with positive slope are,

Pressure versus temperature

Volume versus temperature

4. Pressure = 63.7 atm

1 atm = 760 mmHg

So,

63.7 atm = 63.7 x 760 = 48412 mmHg
