What is the formula for calculating the heat transfer by conduction?
Step 1: Understand that heat transfer by conduction is the process of heat moving through a material.
Step 2: Identify the formula for heat transfer by conduction: Q = kA(T1-T2)/d.
Step 3: Break down the formula: Q is the amount of heat transferred, k is the thermal conductivity of the material, A is the area through which heat is being transferred, T1 is the temperature on one side, T2 is the temperature on the other side, and d is the thickness of the material.
Step 4: Remember that thermal conductivity (k) tells you how well a material conducts heat.
Step 5: The area (A) is the surface area where heat is being transferred.
Step 6: The difference in temperature (T1 - T2) shows how much heat is trying to move from the hot side to the cold side.
Step 7: The thickness (d) of the material affects how easily heat can pass through it; thicker materials resist heat transfer more.
