Question

A sample of gas is at 78.0 oC. You want to change the volume of the gas from 1.60 L to 0.425 L under constant pressure. What must you do to the temperature of the gas

Answer 1

the rule is V1/T1= V2/T2

so we convert the T1 from °c to kelvin

78+273.15= 351.15 k

1.60/351.15 = 0.425/T2

4.55 ×10-³ = 0.425/T2

then T2 = 93.40 kelvin

hence, we should decrease the temperature
