A sample of gas has volume of 90.5 ml at 45C. What volume will the sample occupy at 0C when the pressure is held constant?

Sagot :

Given: V1= 90.5 mL. T1= 45°C + 273.15= 318.15 K

V2= ? T2= 0°C + 273.15= 273.15 K

Solution:

V2=T2•V1 / T1

V2= 273.15 K • 90.5 mL / 318.15 K

*cancel same variable (K)

V2= 77.70 mL
