Question

A gas fills a balloon at a temperature of 27 C and 101.325 kPa of pressure. What will the pressure of the balloon be if the gas is heated to 127 C?

Answer 1

final pressure=1.33atm

Step-by-step explanation:

Given,

initial pressure (p1)=101.325kpa=1atm

initial temperature (t1)=27+273=300k

final temperature(t2)=127+273=400k

final pressure(p2)=?

now,

p1×t2 =p2×t1

1×400=p2×300

p2=1.33 atm
