Question

pressure must a sample of nitrogen at 27°C and 0.625 atm be taken so that its pressure becomes 1.125 atm at constant volume?

Answer 1

Answer:

T2=540K or 267°c

Explanation:

1. NZ 278°c, 0.625 atm     P1/T1=P2/T2
2. (27-->273=300K)
3. T=?,  1.125 atm
4. 0.625/300=1.125/T2
5. $\frac{0.625}{0.625}$≠T2=$\frac{1.125×300}{0.625}$(divided both sides by 0.625)

Ans: T2=540K or 267°c     How to get 267°c just subtract 540 from 273
