WebDec 23, 2024 · Find the initial and final temperature as well as the mass of the sample and energy supplied. Subtract the final and initial temperature to get the change in temperature (ΔT). Multiply the change in temperature with the mass of the sample. Divide the heat supplied/energy with the product. The formula is C = Q / (ΔT ⨉ m). WebOn the cool day, the temperature of the CO 2 is below the critical temperature of CO 2, 304 K or 31 °C ( [link] ), so liquid CO 2 is present in the cylinder. On the hot day, the temperature of the CO 2 is greater than its critical temperature of 31 °C.
