An ideal gas at 1 atm, 12 L and 300 K is changed to 4 L and 150 K. What is the new pressure in atm?
Answer and explanation
Correct answer: A. 3/2 atm
- Step 1: For a fixed amount of an ideal gas is constant.
- Step 2: atm.
Answer
3/2 atm.
Why not the others: 6 atm: the temperature ratio is inverted. 1/6 atm: the volume ratio is inverted.
