Question

300 ml of gas 27c is cooled -3c at constant temperature the final volume is
​

Answer 1

Answer:

If 300ml of a gas at 27∘ is cooled to 7∘ at constant pressure, then its final volume will be. ⇒V1V2=T1T1⇒V2=V1T2T1=300×280300=280ml.

Answer 2

Given:

300 ml of gas 27°C is cooled to -3°C at constant pressure.

To find:

Final volume of gas.

Calculation:

Since the pressure of the gas is kept constant during change in temperature, hence we can say that Volume of the gas is directly proportional to the Temperature of the gas.

$\therefore \: \dfrac{V1}{V2} = \dfrac{T1}{T2}$

$= > \: \dfrac{300}{V2} = \dfrac{27 + 273}{ - 3 + 273}$

$= > \: \dfrac{300}{V2} = \dfrac{300}{ 270}$

$= > \: \dfrac{1}{V2} = \dfrac{1}{ 270}$

$= > \: V2 = 270 \: ml$

So, final answer is:

$\boxed{ \bf{\: final \: volume \: of \: gas= 270 \: ml}}$
