Energy and thermo chem

Calorie

Heart that raises the temp of 1 g of pure water by 1 C

Energy

Capacity to dowry or to supply heat

Colorimeter

Device used to measure the amount of heat absorbed or released during chemical/phisocla process

Enthalpy

Heat content of a substance

Joule

SI unit of heat and energy

Molar heat of fusion

Heat absorbed by 1 mole of substance in MELTING from S to L at CONSTANT temp

Hess law

2 or more thermochemistry erquasions added to give final equation heat changes added to determine final change

M heat of solution

Heat change caused by dissolution of 1 mole of substance

Endothermic

Chemical change where heat is absorbed

Exothermic

Process that loses heat to the surrounding

Standard heat of formation

Change in engthalpy that accompanies formulation of 1 mole of compound form elements, with all substance starting in statdard states at 25C

Heat

Form of energy that always floes from a warmer object to a cooler object

Specific heat

Amount of heat required yo change the temp of 1 g of an object by 1C

Heat of a reaction

Heat change for a reaction

Heat capacity

Amount of heat required to change the temp of object by 1C

Law of conservation of energy

In any chemical process energy is not created nor destroyed
