Question

40 litres of nitrogen at 400 K was cooled by 50 degree Celsius without change in pressure. The percentage contraction in volume will be ?​

Answer 1

Answer:

use ideal gas equation

PV = nRT

$\frac{v1}{v2} = \frac{t1}{t2}$

$\frac{40}{v2} = \frac{400}{323}$

$v2 = 32.3$

$\% = \frac{40 - 32.3}{100}$

$\% = 0.077$
