A gas at 4 atm and volume 12 litres is compressed isothermally to 2 litres. What is the new pressure?
Answer and explanation
Correct answer: D. 24 atm
- Step 1: At constant temperature , so atm. Answer: 24 atm. Why not the others: 2/3 atm: inverts the ratio. 14 atm: adds and subtracts the numbers. 96 atm: multiplies all three.
