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

T2=540K or 267°c

Step-by-step 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. 
   `(0.625)/(0.625)`≠T2=
   `(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
