Compléter ThermochemistryVersion en ligne Fill in the blanks with what you know about heat transfer and thermochemistry. par Devon Heath 1 water temperature specific negative grams release temperatrue energy mass endothermic positive gC in heat higher Tinitial Tfinal exothermic absorb hot J change equal calorimeter Joules lower cold Thermochemistry is the study of heat transfer from a object to a object . Endothermic reactions heat energy . Exothermic reactions heat energy . Freezing water and condensation are processes . Melting water , boiling water , and burning propane are all processes . In the equation q = mcT , q represents the . The units on q are . A q value indicates an exothermic process . A q value indicates an endothermic process . In the equation q = mcT , m represents the . The units on m are . In the equation q = mcT , c represents the . The units on c are / . In the equation q = mcT , T represents the . T can be expanded into - . If Tfinal is than Tinitial , heat energy was lost . If Tfinal is than Tinitial , heat energy was gained . A high c value means that an object can absorb a lot of heat before changing in . Metals have low c values and that is why they are used for cooking . The specific heat of is 4 . 18 J / gC . A is a device that is filled with water . It is used to measure the amount of heat absorbed or lost by the water as an indirect way of measuring the amount of heat absorbed or lost by a reaction . The amount of heat gained by the water and lost by the reaction or metal in a calorimeter are .
