6. A certain freezing process requires that room temperature be lowered from 40°C atthe rate of 5°C every hour. What will be the room temperature 10 hours after theprocess begins?10- About the author Ayla
Answer: Step-by-step explanation: The room temperature 10 hours after lowering from 40°C at the rate of 5°C every hour is -10°C. If we keep lowering the given temperature by 5°C every hour from the initial temperature of 40°C, the temperature will decrease every hour. Explanation: Since there is a decrease in temperature by 5°C every hour, let’s first find the total decrease in 10 hours: or, 10 × 5 = 50°C. This means that after 10 hours, there is going to be a decrease in temperature by 50°C. Since ‘decrease’ refers to the subtraction operation, let’s find the total decrease in temperature from the initial temperature of 40°C as: or, 40 – 50 = -10°C. Therefore, the room temperature 10 hours after the process begins is -10°C. Reply
