Class 10th - Chemistry Definitions

Chemical Equilibrium: Chemical equilibrium is the state in a reversible reaction where the rate of the forward reaction is equal to the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time.

Glossary of Chemistry Term

Glossary of Chemistry

This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions; it features an extensive vocabulary and a significant amount of jargon.

absolute zero

A theoretical condition concerning a system at the lowest limit of the thermodynamic temperature scale, or zero kelvins, at which the system does not emit or absorb energy (i.e. all atoms are at rest). By extrapolating the ideal gas law, the internationally agreed-upon value for absolute zero has been determined as -273.15 °C (−459.67 °F; 0.00 K).

absorbance

The physical or chemical process by which a substance in one state becomes incorporated into and retained by another substance of a different state.

Difference Between Mass and Matter

Mass and matter are two terms that we often hear about both in chemistry and physics classes. Besides, these are two important principles that science students need to understand very clearly and not get confused between them. Most of the time, because of their close relation and an assumption that they can be used interchangeably students tend to misplace the words.

Difference Between Oxidation and Reduction

The chemical reactions which often work together are oxidation and reduction. During this reaction there is an exchange of electrons. When reduction oxidation reactions occur simultaneously it is called as redox reaction or reduction- oxidation reaction.

Difference Between Sodium Carbonate and Sodium Bicarbonate

However, even though sodium carbonate and sodium bicarbonate sound similar in their names, these two substances are not the same and have many features and uses that are different.

Difference Between Atomic Weight and Atomic Mass

Atomic mass and atomic weight do not mean the same but still some people use the terms interchangeably. To make you understand how atomic mass and atomic weight are different from each other, some major differences between atomic mass and atomic weight mentioned below:

Difference Between Fluid and Liquid

It is also worth mentioning that liquids are fluids but not all fluids are liquids. It is mainly because fluids also comprise substances in a gaseous phase. To give you an example, Nitrogen gas is a fluid, whereas a mango juice is both a fluid and a liquid.

Difference Between Evaporation and Condensation

When we study liquids in chemistry, we tend to hear words like evaporation and condensation a lot. While these words tend to sound the same but there are totally different when it comes to the nature of the processes.

Difference Between Atom and ION

To make you understand how atom and ion are different from each other, here are the some major differences between atom and ion:

Difference Between Elements and Atoms

Before getting into the major differences, let’s have a look at what these terms mean. So, an element is basically a pure or raw chemical substance that consists of one or a certain type of atom. An element is categorized based on its atomic number. They have been classified and grouped as metal, metalloids and non-metals in the periodic table.

Difference Between Glucose and Fructose

Important carbohydrates required for the body are glucose, fructose, and sucrose. Glucose and fructose are simple sugars. Simple carbohydrates are classified into two types. They are monosaccharide and disaccharide.

Difference Between Alkali and Base

To make you understand how alkali and base are different from each other, here are some of the major differences between alkali and base:

Difference Between Cell and Battery

Batteries and cells are an important invention that have made a lot of our everyday tasks and life much easier. They are practically used in most of the portable electronic devices that we use today.

Thermosetting Plastics (Thermoplastic Vs Thermosetting Plastics)

Talking about the differences between thermoplastic and thermosetting plastic, well the main distinguishing factor between the two is that, thermoplastic materials typically have low melting points due to which they can further be remoulded or recycled easily.

Difference Between Vaporization and Evaporation

Differences between vaporization and evaporation are here to further understand that these two processes are not exactly the same. Usually, many people tend to be confused about these two processes and many a time these terms are misunderstood.
