The correct answer is C) Expanding gases push magma through the pipe. The mantle is already made of magma, the magma cools when the volcano has already erupted, and the temperature does not decrease in the chamber.

During which two minutes time period is the temperature of water changing faster?!
Vlad1618 [11]

Answer:

2-4 minutes

Explanation:

Fastest changing temperature means larger change in temperature when subtracting final temperature from initial temperature in a given time period (given time period is 2 minutes for all the options)

For 0-2 minutes, our final temperature was 40 (at 2 min) and initial temperature was  20 (at 0 min), thus temperature change was only 20 C.

For 2-4, our final temperature was 80 (at 4 min) and initial temperature was   40 (at 2 min) thus temperature change was 40 C.

For 4-6, our final temperature was 100 (at 6 min) and initial temperature was   80 (at 4 min) thus temperature change was 20 C.

We are not given temperature at 8 min so option D is invalid.

As we can clearly see that in a given 2 minute period, option B has the fastest change because it changed 40C when compared to other options that changed only 20C from starting temperature.

Hope that makes sense.
