Study Notes
Calorimetry Basics
- Calorimetry measures the heat of a reaction or a physical change.
- It is a technique used to measure the amount of heat energy absorbed or released during a chemical reaction or physical change.
Types of Calorimetry
- Reaction calorimetry measures the heat released or absorbed during a chemical reaction.
Adiabatic Calorimetry
- The principle of adiabatic calorimetry is that the system is isolated from the surroundings, and no heat is exchanged between the system and the surroundings.
Calorimetry Principles
- Calorimetry is based on the principle of heat transfer and the laws of thermodynamics.
Calorimeter Purpose
- The purpose of using a calorimeter is to measure the heat of a reaction or a physical change accurately.
Heat Measurement
- The unit of measurement for heat in calorimetry is usually joules (J) or calories (cal).
Experimental Factors
- The most important factor in calorimetry experiments to ensure accurate results is maintaining a well-controlled and isolated environment.
Bomb Calorimetry
- The principle behind bomb calorimetry is that the reaction occurs in a closed system, and the heat is transferred to the surroundings, which is usually water, to measure the heat of the reaction.
