The graph below represents the relationship between time and temperature as heat is added
at a constant rate to a sample of a substance.
Temperature
В.
Time
During interval AB which energy change occurs for the particles in this sample?
A)
The potential energy of the particles increases.
B)
The potential energy of the particles decreases.
C)
The average kinetic energy of the particles increases.
D)
The average kinetic energy of the particles decreases.

Answer 1

Answer:

C: The average kinetic energy of the particles increases.

Explanation:

As the heat energy increases, the temperature rises and cause the

average kinetic energy of the particles increases.

But you should upload the graph that was provided with the question

Answer 2

Answer: 1) the potential energy of the particles increases

Explanation:

it just is
