Question 6 options:
A)
The temperature of the substance will change rapidly as heat is lost until the state changes completely.
B)
The substance releases heat but won't change temperature until the state changes completely.
C)
The substance changes temperature at the same rate before, during, and after the change of state.
D)
The heat is cycled back into the substance, causing the temperature to increase.
1 answer
The correct option is:
B) The substance releases heat but won't change temperature until the state changes completely.
At the critical temperature of a substance, when heat is removed, it generally undergoes a phase change (such as from gas to liquid) without a change in temperature until the phase change is complete. During this time, heat is released, but the temperature remains constant until the state transition is fully finished.
