A certain liquid has a boiling point of 60 degrees Celsius and a melting point of -24 degrees Celsius.

This substance is placed in a refrigerator with a temperature of -41 degrees Celsius.

The temperature of the liquid is measured, and the following graph is produced.

What is the temperature of the indicated point?

Answer choices:
A. -41 degrees Celsius
B. 0 degrees Celsius
C. -24 degrees Celsius
D. 100 degrees Celsius
E. 60 degrees Celsius

Answer :

Answer:

100 degrees, -41 degrees Celcius, and -24 celcius

Explanation:

The substance placed in the refrigerator at -41 degrees Celsius will reach thermal equilibrium and be at the temperature of the refrigerator, which corresponds to answer choice A: -41 degrees Celsius.

Given that the liquid has a boiling point of 60 degrees Celsius and a melting point of -24 degrees Celsius, if this substance is placed in a refrigerator at a temperature of -41 degrees Celsius, the substance would be in a solid state.

Considering that the freezer is below its melting point, and without the ability to view the graph provided, it is logical to assume that the temperature of the indicated point where the substance reaches thermal equilibrium with the freezer should be -41 degrees Celsius.

Therefore, the correct option is A: -41 degrees Celsius.
