Question

The variation of pressure with volume of the gas at different temperatures can
be graphically represented as shown in Figure

On the basis of this graph answer the following questions :

(a) How will the volume of a gas change if its pressure is increased at
constant temperature?

(b) At a constant pressure, how will the volume of a gas change if the
temperature is increased?

Please answer this correctly only if u know the answer.​

Answer 1

Answer:

(i) In accordance to Boyle's law, pressure of a gas is inversly proportional to its volume if temperature is kept constant. Thus, the volume of a gas will decrease if the pressure on the gas is increased keeping the temperature constant. e.g., at 200 K when pressure increases from

to

, volume of the gas decreases,

<br> (ii) In according to lharles law, volume of a gas is directly proportional to its temperature if pressure is kept constant. <br> Thus, on increasing temperature, the volume of a gas will increase if pressure is kept constant. <br> At constant p when we increase the temperature from 200 K to 400 K, the volum of the gas increases,
