Answer 1

Answer:

Hello, everyone I hope this answer would be useful to you!! If so then mark me as BRAINLIEST! Bro your answer is 75% increase

Explanation:

-> If initial temperature is T, final temperature is T+ 100/40×T = 1.4T

-> If initial Volume is V, final volume is V - 20/100 × V = 0.8V

-> Applying the gas equation we get, P1V1/T1 = P2V2/T2

-> If initial pressure is P, final pressure = 1.4T× V× P/ 0.8V× T = 1.75P

-> ∴ Increase in pressure =1.75−1=0.75

-> Percentage increase =0.75×100=75%

THANKS!
