Question from Kinetic Theory of Gases

Answer 1

V/T is constant. Thus V1/T1 = V2/T2

V2=1.04V1 and T2=T1+1

so V1/T1 = 1.04V1/T1+1 ---> Solve it and it comes to 1=0.4T1 hence T1 = 25 degree Celsius

Answer 2

SOLUTION.

For a gas with Volume , Pressure , Temperature , mole .

P.V = n. R. T

TAKE LOG ON BOTH SIDE.

Log[P(1) ] + Log[V(1) ] = Log[n.R] + Log[T(1) ]

Differentiate it.....

∆P/P + 0 = 0 + ∆T/T

VOLUME IS CONSTANT AS THE CONTAINER IS CLOSED.

n. R is constant.

Multiply by 100

(∆P/P). 100 = (∆T/T). 100

(∆P/P) (100) = 0.4......Given

∆T = 1

0.4 = (1/T) 100

T = 100/0.4

T = 250°C

DIFFERENTIAL USED....

dLog(P) = ∆P/P

dLog(T) = ∆T/T
