Covalent Bond
What is Covalent Bond? Covalent bond is a bond formed by atoms, each of atom creates an electron pair and shares it. Because each other’s electrons are shared in pairs, the number…

Charle’s Law
Charle’s Law Assuming constant pressure, increasing the temperature of the gas will speed up the molecular motion. As the gas often collides with the vessel wall, the volume increases. Conversely, if you…

Boyle’s Law
Boyle’s Law If you press the piston of a syringe containing a certain number of gas molecules, the space of the gas molecules is reduced. Therefore, the gas molecules collide with the…

Pascal’s Principle
Pascal’s Principle The Pascal’s principle is as follows. “Suppose a closed tube filled with uncompressed fluid. Then, the pressure of this tube’s inside is the same everywhere.” For example, If you press…
