Answer 1

Dear student this is the answer of your question.

Answer 2

Given :

A cylinder contains a gas at temp of 27 degrees and a pressure 1 mpa .

To Find :

If temp of gas is lowered to -23 degrees the change in pressure is .

Solution :

We know , by gas law :

PV = nRT

Here , we can see that pressure is directly proportional to temperature .

Therefore ,

$\dfrac{P_1}{P_2}=\dfrac{T_1}{T_2}\\\\\dfrac{1}{P_2}=\dfrac{273+27}{273-23}\\\\P_2=\dfrac{250}{300}\ mpa\\\\P_2=0.83\ mpa$

Therefore , this is the required solution .
