Question

4. In an isotropic process, if Tı= 27°C and T2= 127°C, then P/P2 is
3/4
ii. 4/3
iii. 2/3
iv. 3/2​

Answer 1

Answer:

answer is (a) 3/4

Explanation:

we know that P is directly proportional to temperature

t1=27°C=300K and t2=127°C=400K

so$\frac{p1}{t1} = \frac{p2}{t2}$

$\frac{p1}{p2} = \frac{t1}{t2}$

$\frac{p1}{p2} = \frac{300}{400}$

$\frac{p1}{p2} = \frac{3}{4}$
