Question

A certain freezing process requires that room temperature be lowered from
550 C at the rate of 50 C every hour. What will be the room temperature 8 hours
after the process begins ?

Answer 1

Answer:

150 C

Step-by-step explanation:

Temperature lowers in 1 hour = 50 C

Temperature lower in 8 hours = 50 C x 8 = 400 C

Therefore room temperature will be 550C - 400C

= 150C.
