The rate of change is defined as the change in quantity with respect to time.
Answer Statement: If a certain freezing process requires that room temperature be lowered from 40 degree Celsius at rate of 5 degree celsius every hour, the room temperature 10 hours after the process begins will be -10 degrees Celcius.
Step-by-step explanation:
The initial temperature of the room = 40 degrees Celcius
Rate of decrease in temperature = 5 degree Celcius per hour
Time after which temperature is recorded = 10 hours
The final temperature of the room = Initial temperature - rate × time [Since the temperature is lowering every hour]
Final temperature = 40 - 5 × 10
Final temperature = - 10 degree Celcius.
Therefore, the final temperature of the room will be -10 degrees Celcius.
