Question

In the diagram, what is happening to the temperature at Point B? Question 6 options: A. The temperature is rising as the molecules break apart from each other B. The temperature is not rising because the heat is being used to break the connections between the molecules C. The temperature is dropping as the molecules break apart from each other D. The temperature is rising as the substance melts E. The temperature is not rising because the molecules are slowing down

Answer 1

B. The temperature is not rising because the heat is being used to break the connections between the molecules

Answer 2

Answer: The correct answer is option D.

Explanation:

At point B, the temperature becomes constant which means that energy given to the substance is getting used in to the breaking of forces which are present in between the molecules of the substance. These forces are known as inter-molecular forces. Or we can also say that ,at point B the state of the substance is changing.

Hence, the correct answer is option D.
