Question
The temperature, in degrees Celsius (∘C), of a hot object placed in a room is recorded every five minutes. The temperature of the object decreases rapidly at first, then decreases more slowly as the object's temperature approaches the temperature of the room. Which of the following graphs could represent the temperature of this object over time?
The correct answer is:
HINT: Try eliminating the wrong options.
Complete step by step solution:
From the following graphs in the given options,
In option A, the temperature is rapidly decreasing from 250 to 150 in the first 5 minutes, then decreases slowly.
So option A matches the given condition.
In option B, the graph shows an increase in temperature. So option B can be eliminated.
In option C, the graph shows an increase in the temperature. So option C can be eliminated.
In option D, the graph shows a decrease in temperature but very slowly from the starting point itself, contradicting
the given condition.
So option D can be eliminated.
