Question

a certain freezing process requires that room temperature be lowered from 40 degree centigrade at the rate of 5 degree centigrade every hour what will be the room temperature 10 hours after the process begins ​

Answer 1

Step-by-step explanation:

Given:

Present room temperature = 40°C Decreasing the temperature every

hour = 5°C

Room temperature after 10 hours  =

40°C + 10 x (–5°C ) = 40°C – 50°C

= – 10°C

Thus, the room temperature after 10 hours is – 10°C after the process begins.
