Question

from the graph, over which time interval is the temperature rising? 0 - 4 minutes 4 - 8 minutes 10 - 12 minutes none of the above

Explanation:

Step1: Analyze the graph

In a temperature - time graph, when the temperature is rising, the graph has a positive slope.

Step2: Check each interval

• For the interval \(0 - 4\) minutes: The graph has a positive slope, so the temperature is rising.
• For the interval \(4 - 8\) minutes: The graph is horizontal (slope \(= 0\)), so the temperature is constant.
• For the interval \(10 - 12\) minutes: The graph is horizontal (slope \(= 0\)), so the temperature is constant.

Answer:

0 - 4 minutes
