The volume of a given mass of air at temperature `27^(@)C` is 100 c.c. if its temperature is raised to `57^(@)C` maintaining the pressure constant, thhen the increase in its volume is

Options

A. 100 c.c.
B. 130 c.c.
C. 10 c.c.
D. 30 c.c.

Answer

C

Explanation

`(V_(2))/(V_(1))=(T_(2))/(T_(1))`
`(V_(2)-V_(1))/(V_(1))=(T_(2)-T_(1))/(T_(1))=(330-300)/(300)`
`V_(2)-V_(1)=(30V_(1))/(300)=10` c.c.
