Answer 2

Answer:

% of air that has escaped = 40%

Explanation:

Given is,

air is heated from 300 K=T1 to 500k T2

what % of air will be escape to the atmosphere ?

solution :

T 1 = 200K v 1 = v T 1

T 1 = 200K v 1 = v T 1T 2 = 500K T 2 = 500K T 2 = 500K T 2 = 500

T 1 = 200K v 1 = v T 1T 2 = 500K T 2 = 500K T 2 = 500K T 2 = 500u 2 = 7 u 2 u 2 u 2 u 2

T 1 = 200K v 1 = v T 1T 2 = 500K T 2 = 500K T 2 = 500K T 2 = 500u 2 = 7 u 2 u 2 u 2 u 2505

T 1 = 200K v 1 = v T 1T 2 = 500K T 2 = 500K T 2 = 500K T 2 = 500u 2 = 7 u 2 u 2 u 2 u 2505overline h pi v 2 = v 1

T 1 = 200K v 1 = v T 1T 2 = 500K T 2 = 500K T 2 = 500K T 2 = 500u 2 = 7 u 2 u 2 u 2 u 2505overline h pi v 2 = v 1=v×500=5v/s

500=5v/sfinal volume - original volume of air escaped

500=5v/sfinal volume - original volume of air escaped=5 v/3-v

500=5v/sfinal volume - original volume of air escaped=5 v/3-vSo,

500=5v/sfinal volume - original volume of air escaped=5 v/3-vSo,% of air that has escaped

V = 2V/3X100 X3/5

=100 × 2/5

=40

% of air that has escaped = 40%
