Question

a sample of helium has a volume of 500cm^3 at which the volume will become 260cm^3 . Assume that the pressure is constant

Answer 1

Initial volume of helium gas (V1) = 500 cm3
Final volume of gas (V2) = 260 cm3
Initial temperature (T1) = 373 K
Final temperature (T2) = We have to find
According to Charles law :
V1/T1=V2/T2
500/373=260/T2
T2=193.8k
