Question

i) Volume of a gas is 1000 cc at STP. What will be the
volume of the gas if the temperature is increased
by 10 K at a constant pressure?​

Answer 1

Answer:

Given —

Temperature increased to 10k

Volume increases by 0.2 %

Let initial Volume be V✔

And initial Temperature is T✔

We have ideal equation

PV = nRT

Since pressure is constant

Here R is also constant

Therefore Ratio will be in proportion

⇒V is proportional to T

⇒V ∝ T

Final Volume =

V + \frac{0.2}{100} V \\ \\ = 1.002V

Final Temperature

= T + 10

___________________________

WE HAVE V ∝ T

\frac{V}{1.002V} = \frac{T}{T + 10} \\ = > T + 10 = 1.002T \\ \\ on \: solving \\ = > T = 5000 K
