Question

a certain freezing process. requires. temperature to be. reduced from 38°c to -10°c. in 12hours .find the rate at which temperature decreases​

Answer 1

Answer:

Rate of decrease of temperature is 4°C per hour.

Step-by-step explanation:

Given :

Initial Temperature = 38°C

Final Temperature = - 10°C

Time taken to reduce the temperature = 12 hours

So, change in the temperature

= Final Temperature - Initial Temperature

= -10°C - 38°C

= - 48°C

Rate of change of temperature = change/ time

= - 48°C / 12 h

= - 4°C/h

So, the rate at which temperature decreases is 4°C per hour.
