Question

A sample of gas has a volume of 25 L at a pressure of 200 kPa and a temperature of 25°C. What would be the volume if the pressure were increased to 250 kPa and the temperature were decreased to 0°C?

Answer 1

`18.32"L"`

Explanation:

`(P_1V_1)/T_1=(P_2V_2)/T_2`

You need to convert degC to Kelvin by adding 273:

`:.(200xx25)/298=(250xxV_2)/273`

`:.V_2=(200xx25xx273)/(298xx250)`

`:.V_2=18.32"L"`
