CALORIMETRY

Endothermic

(of a chemical reaction or compound) occurring or formed with absorption of heat (energy)

bomb calorimeter

Calorimetry experiments can be performed at a constant volume using this device.

closed system

a system in which no matter is allowed to enter or leave

open system

a system that can exchange both matter and energy with its surroundings

calorimeter

an insulated device used to measure the absorption or release of heat in chemical or physical processes

Exothermic

describes a reaction that releases energy to the surroundings

Change in Enthalpy

equal to the heat gained or lost by a system at constant pressure

DELTA T

final temperature- initial temperature

enthalpy

heat content a substance has at a given temperature and constant pressure

H

symbol for enthalpy

C

symbol for specific heat

calorimetry

the precise measurement of heat flow out of a system for chemical and physical processes
