The room temperature 10 hours after the process begins is -100 C. Suppose the decreased temperature is negative,

Initial temperature = 400 C

Change in temperature per hour = -50 C

Change in temperature after 10 hours = – 5 x 10 = -500 C

the room’s final temperature following the 10-hour freezing process

= 400 C + (-500 C)

= -100 C

Consequently, 10 hours after the process starts, the ambient temperature is -100 C.

A thermometer’s display of temperature, which is expressed on a comparative scale, represents the degree or intensity of the heat contained in a substance or a system. In other words, a temperature is a unit used to describe how hot or cold a body is and is measured in Celsius, Kelvin, and Fahrenheit. The quantity of heat that is released or absorbed determines how much the temperature changes. Kelvin is the SI unit for temperature.

The formula for temperature is provided by,

Δ T = Q / mc

Where,

Q = amount of heat absorbed or released,

Δ T = temperature difference,

m = mass of the body,

c = specific heat of the body.

Summary:

## A certain freezing process requires that room temperature be lowered from 40 degree Celsius at rate of 5 degree Celsius every hour what will be the room temperature 10 hours after the process begins?

A certain freezing process requires that room temperature be lowered from 40 degrees Celsius at the rate of 5 degrees Celsius every hour. The room temperature 10 hours after the process begins is -100 C.
