It is found, on heating a gas, its volume increases by 50% and pressure decreases to 60% of its original value. If the original temperature was -15C, FIND THE TEMPERATRE TO WHICH IT WAS HEATED ?

Let the initial pressure be = a

Let the initial volume = b

Let the initial temperature = 15 degree Celsius = 15 + 273 = 288K

Final pressure = a – 60a/100 = a – 3a/5 = 2a/5

Final volume = b + 50b/100 = b + b/2 = 3b/2

Final temperature = 3/5 x 288 = 172.8K
