Question

A certain freezing process requires that room temperature be lowered from 30°C at the rate of 4°C every hour. What will be the room temperature 5 hours after the process begins?

Answer 1

=10°C

Step-by-step explanation:

initial temperature=30°C

Rate of decrease of temperature per hour=4°C

In 5 hr it decreases = 4*5

=20°C

SO, temperature after 10 hrs

= 30-20

=10°C
