Q = mc∆T. Q = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/kg∙K) ∆ is a symbol meaning "the change in" ∆T = change in temperature (Kelvins, K)

q = m x C x ΔT. Where: q = heat absorbed or released. m = mass. C= specific heat of the substance in joules/g °C or in calories/g °C. ΔT = change in temperature. The chemist often works with the unit of energy known as the joule, but it is common in the US to refer to calories rather than joules when looking at energy.

2014年9月8日 · The variables in the equation q = mCDeltaT mean the following: " let:" q="heat energy gained or lost by a substance" m="mass (grams)" C="specific heat" DeltaT="change in temperature" Note that DeltaT is always calculated as "final temperature "-" initial temperature", not the other way around.

3:03 calculate the heat energy change from a measured temperature change using the expression Q = mcΔT; 3:04 calculate the molar enthalpy change (ΔH) from the heat energy change, Q; 3:05 (Triple only) draw and explain energy level diagrams to represent exothermic and endothermic reactions

Study with Quizlet and memorize flashcards containing terms like Heat Capacity (C) formula, Specific Heat Capacity (c), H2O specific heat and more.

In the formula , Q=mxcxT which quantity is measured in units of J/g·°C? What does a calorimeter directly measure? radiation. The specific heat of copper is 0.385 J/g·°C. Which equation would you use to calculate the amount of heat needed to raise the …

At GCSE Q=mcΔT would have been enough, but an A level paper is likely to ask you to calculate ΔH neutralisation or ΔH reaction which are always defined as being an enthalpy change for 1 mole. So...
