A certain freezing process requires that the room temperature be lowered from 40 c at the rate of 5 C every hour. what will be the room temperature 10 hours after the process begins? |

Answer» ong>Answer: Hope This Will Help You Step-by-step EXPLANATION: Given that
Let us assume that the lowered temperature as NEGATIVE,
Initial temperature = 40 degree C elsius
Change in temperature PER hour = -5 degree Celsius
Change in temperature after 10 hours = (-5) × 10 = -50 degree C elsius
∴The final room temperature after 10 hours of freezing process = 40 degree Celsius + (-50oC)
= -10oC
The room temperature 10 hours after the process begins= -10oC |
