Question

gas is heated oc to 100c at 1atm pressure if the initial volume of the gas is 10 l find its volume

Answer 1

V ∝ T

Or, T1 /T2 = V1 /V2
​Since initial temperature is not given i am taking the temperature of starting point as room temperature.
​Let the initial volume be V
​And initial temperature(T1) be room temperature that is 25°C or 298 K (273 K +25)
Then T2 = 127°C​ or (273 K +127 ) 400 K
​Now V2 = V1/T1 x T2 
             = V ×400 K298 K
           = 1.34 V
​Increase in volume = 1.34 V -V = 0.34 V
% increase in volume = 0.34 V/V x 100 = 34%
