Delta h and q relationship
WebApr 10, 2024 · From equation (1) and (2) we get that q = m C p Δ T. Therefore, both the equations H = m C T and q = m C T are the same. Note: When heat is added, the temperature will change by a certain amount. The relationship between heat and temperature differs in every substance by the amount of specific heat. The relationship … WebFeb 28, 2016 · H = E + P V Using First Law, we get d H = δ Q − ( ∑ Y d X + W ′ ⏟ δ W) + d ( P V) where ∑ Y d X = configuration work W ′ = dissipative work When the process is …
