A certain control heating process requires that the temperature be raised from − 23 ∘ C at the rate of 4 ∘ C every hour . Find the temperature after 12 hours .

Respuesta :

Answer:

Temperature after 12 hours = 25°C

Step-by-step explanation:

Given:

Current tempreture = -23°C

Tempreture incresing rate = 4°C per hour

Total time = 12 hour

Find:

Temperature after 12 hours

Computation:

Temperature after 12 hours = Current tempreture + (Tempreture incresing rate)(Total time)

Temperature after 12 hours = -23 + (4)(12)

Temperature after 12 hours = -23 + 48

Temperature after 12 hours = 25°C
