WebAssuming that all heat transfer was between the rebar and the water, with no heat “lost” to the outside environment, then heat given off by rebar = −heat taken in by water, or: q rebar = − q water Since we know how heat is related to other measurable quantities, we have: ( c × m × Δ T) rebar = − ( c × m × Δ T) water Web∆h or change in enthalpy is calculated by either observing the difference in enthalpy of products and reactant or by using the formula ∆H = cm∆T Conclusion: Delta H is …
