Question

A gas occupies a volume of 580 ml at 17 ºC. It is heated to 100 ºC at constant pressure. Calculate the volume of the gas -

(1) 746 ml. 

(2) 760 ml.

(3) 773 ml. 

(4) 780 ml.

Answer 1

Correct Answer is: (1) 746 ml. 

Initial volume (V₁) = 580 ml,

T₁ = 17 + 273 = 290 K

Final Volume (V₂) = ?

T₂ = 100 + 273 = 373 K

_V1/T₁ = V₂/T₂ ;

∴ V₂ = T₂ × V₁/T₁ = 373 x 580/290 = 746 ml,
