Question

a certain mass of gas occupies a volume of 2 dm3 at STP keeping the pressure constant at what temperature would the gas occupies a volume of 4 dm3​

Answer 1

Hi there,

♤ Given

● Gas at STP

● T1 = 273 °k

● V1= 2 dm3= 2L

● T2 = ???

● V2 = 4 dm3

☆ Charles law is V1/T1 = V2/T2

volume is directly proportional with temp at constant pressure and amount of gas

So,

2÷273 = 4÷ T2

☆ T2= 4×273÷2 = 546 °k
