Question

100ml of gas at 27°C is cooled to 10°C at constant pressure. Calculate the volume of the gas at 10°C.​

Answer 1

At constant pressure, Volume is directly proportional to Temperature,

$\frac{v1}{v2} = \frac{t1}{t2} \\ = \frac{100}{v2} = \frac{273 + 27}{273 + 10} \\ \frac{100}{v2} = \frac{300}{283} \\ 100 \times 283 = v2 \times 300 \: \: \: \: \: \: cross \: multiplication \\ 100 \times 283 = v2 \times 300 \\ \\ 2830</em></strong><strong><em> = v2 \times 300 \\ v2 = 94. 3ml$
