Change in Temperature given Thermal Conductivity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Change in Temperature = (Heat Flow Rate*Thickness of Sample)/(Sample Area*Thermal Conductivity)
∆T = (Q*L)/(A_sample*k)
This formula uses 5 Variables

Variables Used

Change in Temperature - (Measured in Kelvin) - The Change in Temperature is the difference between the initial and final temperature.
Heat Flow Rate - (Measured in Watt) - Heat Flow Rate is the amount of heat that is transferred per unit of time in some material, usually measured in watt. Heat is the flow of thermal energy driven by thermal non-equilibrium.
Thickness of Sample - (Measured in Meter) - Thickness of Sample is the measure of the distance between two surfaces of an sample, usually the smallest of three dimensions.
Sample Area - (Measured in Square Meter) - Sample Area is defined as the space occupied by the surface of a sample.
Thermal Conductivity - (Measured in Watt per Meter per K) - Thermal Conductivity is rate of heat passes through specified material, expressed as amount of heat flows per unit time through a unit area with a temperature gradient of one degree per unit distance.

STEP 1: Convert Input(s) to Base Unit

Heat Flow Rate: 125 Watt --> 125 Watt No Conversion Required
Thickness of Sample: 21 Meter --> 21 Meter No Conversion Required
Sample Area: 52.6 Square Meter --> 52.6 Square Meter No Conversion Required
Thermal Conductivity: 10.18 Watt per Meter per K --> 10.18 Watt per Meter per K No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

∆T = (Q*L)/(A_sample*k) --> (125*21)/(52.6*10.18)

Evaluating ... ...

∆T = 4.90225372944789

STEP 3: Convert Result to Output's Unit

4.90225372944789 Kelvin --> No Conversion Required

FINAL ANSWER

4.90225372944789 ≈ 4.902254 Kelvin <-- Change in Temperature
