calculate volume

Question

A given mass of chlorine has a volume of 40 cm3 at 20 °C. Calculate its volume at 50 °C if the pressure remains constant.

Answer 1

Initial volume of the chlorine,V₁  = 40 cm³

Initial temperature,T₁ =20°C =293 K

Final temperature,T₂ =50°C =323 K

Using the ideal gas equation.

T₁ V₁ =T₂ V₂

(40)(293) =(V₂)(323)

V₂= (40)(293)/323 = 36.28 cm³

Therefore, the volume at 50°C is 36.28 cm³
