If absolute temperature of a gas is doubled and the pressure is reduced to one half, what will happen to the volume off the gas ​

Increase four-fold

Explanation:

(c) Increase four-fold

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

where,

= initial pressure of gas = p

= final pressure of gas =

= initial volume of gas = v

= final volume of gas = ?

= initial temperature of gas = t

= final temperature of gas = 2t

Now put all the given values in the above equation, we get the final pressure of gas.

Therefore, the temperature of gas will increase four-fold.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
