Question

A gas in a cylinder with movable piston has an initial volume Of 88.2 ML at 35°C. The cylinder is heated at constant pressure until the volume becomes 123 ML. What was the temperature in degrees Celsius to which the gas was heated

Answer 1

The temperature in degree celsius to which the gas was heated is calculated using the Charles law formula

that is V1/T1 =V2/T2
V1=88.2 ml
T1=35 +273 = 308 K
V2=123 ml
T2=?

by making T2 the formula of the subject T2=V2T1/V1

=(123 ml x308 k)/88.2 ml =429.5 K

in degree celsius = 429.5 -273= 156.5 degree celsius
