Question
The substance sulfur dioxide has the following properties:
normal melting point: 200.4 K
normal boiling point: 263.1 K
triple point: 1.7×10-3 atm, 197.6 K
critical point: 78 atm, 430.7 K
A sample of sulfur dioxide at a pressure of 1.00 atm and a temperature of 223.4 K is cooled at constant pressure to a temperature of 202.2 K. Which of the following are true? Choose all that apply:
The final state of the substance is a liquid.
The final state of the substance is a solid.
No phase change will occur.
The solid initially present will vaporize.
The sample is initially a liquid.
Explanation / Answer
Initially the compound is in liquid state as it is having the temperature(223.4 K) below its B.P.(263.1 K). the final temperature of the system is 202.2 K, it is more than the M.P 200.4 K. Hence the compound is in liquid state.
So the answer is - The final state of the substance is a liquid.
No phase change will occur.
The sample is initially a liquid.
