Question 1
Kinetic Theory and States of MatterUse the graph below to answer questions 1 and 2.
If the gas is cooled, at what temperature will it start to condense?
- A.125°C
- B.150°C
- C.175°C
- D.250°C
Show the answer and explanation
Answer: B (150°C)
Explanation
The flat part of the graph between 3 and 6 minutes is at 150°C: this is the boiling point, and a gas condenses at the same temperature at which the liquid boils.
