Question

. In a chemistry lab, the room temperature is
required to be lowered from 80°C at the rate
of 5°C every hour. What will be the room
temperature after 10 hours?​

Answer 1

Answer: Required temperature of chemistry lab = 80° C

Rate of temperature every hour= 5

Difference between both= 80-5= 75

Therefore , the room temperature of room after 10 hours is 75° C.

Step-by-step explanation: Thank you I hope my answer will help you.

Answer 2

Answer:

Room temperature = 80°C

Cooling rate = 5°C every hour

Therefore,room temperature after 10 hours = 30°C

Step-by-step explanation:

Room temperature after 1 hour = 75°C

Room temperature after 2 hour = 70°C

Room temperature after 3 hour = 65°C

Room temperature after 4 hour = 60°C

Room temperature after 5 hour = 55°C

Room temperature after 6 hour = 50°C

Room temperature after 7 hour = 45°C

Room temperature after 8 hour = 40°C

Room temperature after 9 hour = 35°C

Room temperature after 10 hour = 30°C
