Question

Considering the temperature vs. time graph below, how does the temperature at the beginning of a change of state

compare with the temperature at the end of the change?

The temperature is always lower.
O The temperature is always the same.
O The temperature is usually lower.
O The temperature is usually higher.

Answer 1

Answer: O The temperature is usually higher.

Explanation:

Based on the given temperature vs. time graph, it appears that the temperature at the beginning of a change of state is usually higher than the temperature at the end of the change.

The graph shows a decreasing temperature as time progresses, which suggests that the initial temperature is higher (at the left side of the graph) compared to the temperature at the end of the change (at the right side of the graph).

So, the correct answer is: "The temperature is usually higher."
