Question

6. A certain freezing process requires that
room temperature be lowered from 80° C
at the rate of 10° C every hour. What will
be the room temperature after 10 hours the
process begins?​

Answer 1

❤HEY MATE❤

Here is your answer:-

➡️Initial temperature = 40*C

➡️Room temperature decreases at 5*C per hour

➡️ Therefore, Temperature change in 1 hour = - 5 *C

➡️Temperature change in 10 hours = -5 ❌10*C= -50*C

➡️Room temperature after 10 hours

➡️ Initial temperature + Temperature Change in 10 hours = 40+(-50)=-10*C
