the room temperature after 8 hours process begins is 10°c
step by step explanation:
since we have given that
room temperature= 50°c
at every hour it reduces at the rate of 5°c
so after 8 hours it reduces by
8× -5°c
= -40°c
so room temperature after 8 hours it becomes 50°c -40°c = 10°c
hence the room temperature after 8 hours the process begins is 10°c
