Question

gas occupied 100ml at 50 degrees Celsius and 1 atm pressure .the gas is cooled at constant pressure so that volume is reduced to 50ml. What is the final temperature

Answer 1

V1/T1 = V2 / T2
T2=V2×T1/V1
=50×323/100
=323÷2
=161.5K
=-111.5C

Answer 2

V1 =V2T2

V1=37.5

lT1=35+273=308

degrees K

V2=3.0l

T_2 = unknown

Substituting these numbers into the equation gives

37.5308=3.0T2

multiplying across gives

A gas occupied 100ml at 50 degrees Celsius and 1 atm pressure.

The gas is cooled at constant pressure so that volume is reduced to 50ml.
