What does a rapid decrease in temperature indicate about the cooling process of a substance?.
- A.The substance is losing thermal energy quickly.
- B.The substance has reached thermal equilibrium.
- C.The substance is gaining thermal energy.
- D.The substance is at a constant temperature.
Model answer
What a good answer should say
- The substance is losing thermal energy quickly.
Explanation
Why this works
The evidence shows that a rapid decrease in temperature suggests that the substance is losing thermal energy at a fast rate. This implies that the cooling process is effective, leading to a significant drop in temperature.
Therefore, we can conclude that the substance is undergoing a quick cooling process.
