Answer :
The air conditioner will take 10 minutes to bring the room temperature down to 25°C.the air conditioner will take 10 minutes to bring the room temperature down to 25°C, creating a comfortable living condition during the peak summer.
Given that the initial room temperature is 45°C and the desired temperature is 25°C, the temperature difference that needs to be reduced is 45°C - 25°C = 20°C. The air conditioner reduces the temperature by 2°C per minute, so it will take 20°C / 2°C per minute = 10 minutes to bring the room temperature down to 25°C.
To solve this problem, we need to calculate the time it takes for the air conditioner to bring the room temperature from 45°C to 25°C with a cooling rate of 2°C per minute.
The temperature difference that needs to be reduced is 45°C - 25°C = 20°C. The air conditioner can reduce the temperature by 2°C per minute. So, the time required to reduce the temperature by 20°C at a rate of 2°C per minute is calculated as follows:
Time = Temperature difference / Cooling rate = 20°C / 2°C per minute = 10 minutes.
Therefore, the air conditioner will take 10 minutes to bring the room temperature down to 25°C, creating a comfortable living condition during the peak the air conditioner will take 10 minutes to bring the room temperature down to 25°C, creating a comfortable living condition during the peak summer..
