Question

A gas occupies 900.0 mL at a temperature of 27.0 ˚C. Assuming constant pressure, what is its volume if it is heated to 132.0 ˚C?

Answer 1

Answer:

new volume is 1215mL

Explanation:

using Charles law , the volume of a fixed mass of gas is directly proportional to its temperature provide that pressure is kept constant.

$\frac{V1}{T1}=\frac{V2}{T2}$

V1=900mL ,

convert the temperatures from Celsius to kelvin temperature.

T1 =27°C =27+273 =300K

T2 =132°C = 132+273=405K

$V2=\frac{V1T2}{T1}$

$V2=\frac{900*405}{300}$

V2= 1215mL
