On what principle does Calorimetry depend?

Centerjava.com – We know that Calorimetry is the process of measuring the amount of heat released or absorbed during a chemical reaction. Here we know that whether the chemical reaction is exothermic or endothermic, so, on what principle does Calorimetry depend? We see the explanation below.

## On what principle does Calorimetry depend?

The answer is the law of conservation of energy

Then here the explanation:

In the Law of conservation of energy: energy is eternal and cannot change over time, has the same value, either before something happens or afterward.

Energy can change shape but the amount of energy will always be the same.

To find out Calorimetry is a calorimeter.

### Definition of Calorimeter

A Calorimeter is a device to determine calories by measuring changes in temperature and changes in thermal effects.

A Calorimeter is also a tool in some experiments related to calories. This tool allows minimum heat transfer to the surrounding environment, calorimeter consists of two vessels separated by an air space; To reduce heat absorption by the vessel wall, aluminum is as material on the vessel wall

The lid of the vessel is made of wood which is a bad conductor so that not much heat is lost, calorimeters can be used to measure the heat of a substance.

To detect the heat that is owned by an object that is by measuring the temperature of the object, If the temperature is high, the heat contained by the object is very large, and vice versa if the temperature is low then the heat contained is small.

The heat contained by the object is very large, and vice versa if the temperature is low then the heat contained is small.

#### Heat Transfer

There are 3 ways of heat transfer, namely:

1. Conduction: heat transfer without mass transfer or substance particles, conduction occurs in solids.
2. Convection: heat transfer accompanied by mass transfer or substance particles, occurs in liquids and gases.
3. Radiation: heat transfer in the form of electromagnetic waves (do not need a medium), for example, the sun.

#### Calorimeter function

The following are some of the calorimeter functions including:

• Measuring the amount of heat a chemical reaction changes
• Detects heat a chemical reaction changes
• Calculates the amount of heat a chemical reaction changes
• As a tool for experimental researchers on heat
• Detects temperature in the heat
