Question

Q-2 Give reasons for the following
temperature remaining constant the product of the volume and the pressure of the given mass of dry gas is a constant ​

Answer 1

Answer:

The relation between pressure and volume at constant temperature is best described As Boyle's Law, which says that at constant temperature, the pressure of a fixed amount of gas is inversely proportional to its volume. Or in other words we can say that the product of pressure and volume is constant, pV = constant.

Answer 2

Answer:

At constant temperature, the volume of a given mass of a dry gas is inversely proportional to its pressure. The product of the volume and pressure of a given mass of dry gas at a constant temperature is constant, according to Boyle's law.

Explanation:

If the pressure remains constant :

Then  

According to Boyle's law  

V α 1/P

and

V = K x 1/P  

OR VP = k  

hence the product of pressure and volume is constant.

Boyle's law states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant
