One litre of an ideal gas st `27^(@)C` is heated at a constant pressure to the `297^(@)C.` Then, the final volume is the approximately

Options

A. 1.2 L
B. 1.9 L
C. 19 L
D. 2.4 L

Answer

B

Explanation

By Charles's law , `(V_(1))/(V_(2))=(T_(1))/(T_(2))rArrV_(2)=(V_(1)T_(2))/(T_(1))`
`therefore` The final volume of the gas `V_(2)=1xx((297+273))/((27+273))`
`rArr " " V_(2)=(570)/(300)`
`rArr " " V_(2)=1.9L`
