A gas at 1 atm and volume 12 litres is compressed isothermally to 5 litres. What is the new pressure?
Answer and explanation
Correct answer: B. 2.4 atm
- Step 1: At constant temperature , so atm. Answer: 2.4 atm. Why not the others: 5/12 atm: inverts the ratio. 8 atm: adds and subtracts the numbers. 60 atm: multiplies all three.
