Question

a certain freezing process requires that room temperature be lowered from 40 degree Celsius at the rate of 5 degree Celsius every hour what will be the room temperature 10 hours after the process begins​

Answer 1

Step-by-step explanation:

5degrees per hour

1 hour _ -5degrees

temperature at the beginning=40°C

temperature after 10 hours= temperature at the beginning + temperature reduced

=40°C+(-50°C)

=-10°C
