Question

when a gas filled in a clossed vessel is heated through 1 c its pressure id increased by 0.4%.the initial temperature of the gas was​

Answer 1

Hello Mate!!

Answer:-

Let P2 = 1.004 P1 ..... A 0.4% increase in P

Let T2 = T1 + 1 ........... See note below

P1V1/T1 = P2V2/T2 ..... combined gas law

P1/T1 = P2/T2 ............... Assume V remains constant.

T1 = P1T2 / P2 .............. solve for T1

T1 = P1(T1+1) / (1.004P1)

T1 = (T1+1) / 1.004

1.004T1 = T1 + 1

1.004T1 - T1 = 1

0.004T1 = 1

T1 = 1 / 0.004

T1 = 250K

Note: A 1 degree increase on the Celsius scale is a 1 degree increase on the Kelvin scale. Temperatures used in the

Explanation:

Let P2 = 1.004 P1 ..... A 0.4% increase in P 

Let T2 = T1 + 1 ........... See note below 

P1V1/T1 = P2V2/T2 ..... combined gas law 

P1/T1 = P2/T2 ............... Assume V remains constant. 

T1 = P1T2 / P2 .............. solve for T1 

T1 = P1(T1+1) / (1.004P1) 

T1 = (T1+1) / 1.004 

1.004T1 = T1 + 1 

1.004T1 - T1 = 1 

0.004T1 = 1 

T1 = 1 / 0.004 

T1 = 250K
