Question

a certain freezing process requires that the 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

Answer:

-10 degree Celsius

Step-by-step explanation:

Current temperature = 40 degree Celsius

Rate of cooling = 5 degree per hour

Thus, in 10 hours, cooling will be = 5 x 10 = 50 degrees Celsius

Thus, after 10 hours, cooling will be = 40 + (-50) = 40 - 50 = -10 degree Celsius
