What is the formula for calculating the heat transfer in a substance? (2023)
Step 1: Understand what Q represents. Q is the total heat energy added or removed from a substance.
Step 2: Identify m, which is the mass of the substance. This is how much of the substance you have.
Step 3: Learn about c, the specific heat capacity. This is a property of the substance that tells you how much heat is needed to change its temperature.
Step 4: Know ΔT, which is the change in temperature. This is calculated by subtracting the initial temperature from the final temperature (ΔT = final temperature - initial temperature).
Step 5: Put it all together in the formula Q = mcΔT. This means to find the heat transfer, multiply the mass (m) by the specific heat capacity (c) and then by the change in temperature (ΔT).
