Question

A certain freezing process required that room temperature to 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 1

5 x 10 = 50
40-50= -10
hence the temperature will be -10 degree Celsius

Answer 2

so for every hour 5°c is being reduced
therefore after ten hours there will be a reduce in 5×10=50°c
so 40-50=-10
the answer is -10°c pls mark this answer as brainliest
