Is it safe to boil water inside the microwave oven ?

How does the microwave oven work? Microwaving food is a quick way to heat it up. The microwave works by using electromagnetic radiations, which are waves of electrical and magnetic energy moving together to heat food. These microwaves are reflected within the metal interior of the oven where they are absorbed by food. They can […]

Halogen – Elements, Properties and uses

Is it safe to boil water inside the microwave oven ?

What are halogen atoms ? Halogen elements are the elements of group VII (column 17) in the periodic table. There are 5 halogens (Fluorine, Chlorine, Bromine, Iodine, and Astatine). The sixth element which is Tennessine atom might have some properties in common with the other elements. Fluorine 9F Chlorine 17Cl Bromine 35Br Iodine 53I Astatine […]

Do plants feel pain ?

Plants don’t feel pain the same way humans do. They have some sort of nervous system that is sensitive enough to respond to chemical changes caused by pricking or cutting. But that doesn’t mean they don’t feel something. Some have even been known to express feelings of distress when their roots are being disturbed. Some […]

Noble Gases

Noble gases

The noble gases are the elements of group VIII (Column 18) in the periodic table: Helium 2He Neon 10Ne Argon 18Ar Krypton 36Kr Xenon 54Xe Radon 86Rn These elements have a full valence shell of electrons, Helium has two valence electrons (1s2), the other noble gases each have eight valence electrons that’s why all the […]

The fifth state of matter – Bose Einstein Condensate

Is it safe to boil water inside the microwave oven ?

The fifth state of matter or the Bose Einstein Condensate the has been recently created in the microgravity of the international Space station. This creation is a big achievement for the scientific community. In our daily life we generally interact with three states of matter: solid, liquid and gas. The fourth state or plasma is […]

Gas laws – Gay Lussac’s Law

Relation pressure temperature

The physical behaviour of a gas is described using four main variables : Temperature Pressure Volume Amount (mol number) Gay Lussac’s Law Joseph Louis Gay-Lussac was a French chemist and physicist who was investigating the relation between the pressure and the temperature of a fixed amount of gas at constant volume. Gay-Lussac’s law states that […]

Gas laws – Charles’s Law

Is it safe to boil water inside the microwave oven ?

The physical behaviour of a gas is described using four main variables : Temperature Pressure Volume Amount (mol number) Charles’s law Charles’s law was formulated by the French scientist Jack Charle who was investigating the properties of gases in the 1780’s. This law describes the relation between the temperature and the volume of a gas at […]
