(b) A science experiment requires controlling the temperature of an object as follows:
Step 1: The temperature is increased by 6°C every minute for five minutes.
Step 2: The temperature is decreased by 4°C every minute for three minutes.
Steps 1 and 2 are repeated continuously. If the object's temperature is 15°C before the
experiment begins, what will its temperature be after
(i)
six minutes into the experiment?
(ii) ten minutes into the experiment?

Given : A science experiment requires controlling the temperature of an object as follows:
Step 1: The temperature is increased by 6°C every minute for five minutes.
Step 2: The temperature is decreased by 4°C every minute for three minutes.
Steps 1 and 2 are repeated continuously.
Object’s temperature is 15°C before the experiment begins,
To Find : temperature after six minutes into the experiment
(ii) temperature after ten minutes into the experiment
Solution:
Initial Temperature = 15°C
temperature is increased by 6°C every minute for five minutes
Hence Temperature increased in 5 minutes = 6 * 5 = 30°C
Temperature after 5 minutes = 15 + 30 = 45°C
The temperature is decreased by 4°C every minute for three minutes.
Hence Temperature decreased in next 1 minute = 4°C
Temperature after 6 minutes = 45°C - 4°C = 42°C
temperature after six minutes into the experiment is 41°C
Temperature after 5 minutes = 45°C
The temperature is decreased by 4°C every minute for three minutes.
Hence Temperature decreased in next 3 minutes = 12°C
Temperature after 8 minutes into the experiment is 45 - 12 = 33°C
Then again in next 2 minutes , temperature is increased by 12 °C
Hence temperature after 10 minutes into the experiment is 33°C + 12 °C
= 45°C
