WebThe amount of heat gained or lost by a sample (q) can be calculated using the equation q = mcΔT, where m is the mass of the sample, c is the specific heat, and ΔT is the temperature change. Created by Jay. Sort by: Top Voted Questions Tips & Thanks Want to join the … Web5 de sept. de 2024 · 1. Integrate the heat capacity. 2. Verify via Δ H. From thermodynamics, the heat capacity is defined as C p = ( d H d T) P. That means we can calculate the heat required to change the temperature of some material from the following integral: In the range of 298-1200K, the heat capacity of CO 2 is given by a Shomate polynomial : where t = T ...
