Chemistry is a very important branch of science. Chemistry is the study of science that deals with constituents of matter like atoms molecules, ions etc.; and its properties, structure, behaviour, and interactions among them. Since everything is made up of atoms and molecules, we can see the chemistry all around us. Today, chemistry has grown into a very diverse field. There is a significant overlap between chemistry and other branches of science, for example, biochemistry (chemistry and biology), physical chemistry (chemistry and physics), medicinal chemistry (medicine and chemistry), chemical engineering (chemistry and engineering) etc.
Hydrostatic pressure is the pressure exerted by a fluid at hydrostatic equilibrium on the contact surface due to gravity. If a fluid is confined in a container, the pressure on the bottom and on the walls of the container is due to hydrostatic pressure.
Standard ambient temperature is 25 ℃ or 298.15 K or 77 ℉.
Standard pressure is 1 bar or 100.000 kPa or 750.06 mmHg (or torr) or 14.504 psi.
Normal temperature is 20 ℃ or 293.15 K or 68 ℉.
Normal pressure is 1 atm or 101.325 kPa or 760 mmHg (or torr) or 14.6959 psi.
Chemistry is a branch of science which deals with the study of matter composed of atoms and molecules, their properties, composition, structure, behaviour, and interactions among constituents of matter. Modern chemistry can be categories into five main branches: Physical chemistry, Analytical chemistry, Inorganic chemistry, Organic chemistry, and Biochemistry.
Gay-Lussac's law is also known as pressure law or Amontons's law. The law correlates how the pressure of a gas increases with an increase in temperature. This law is named after French chemist Joseph Louis Gay-Lussac. He formulated this relationship in 1808. Gay-Lussac's law is similar to Charles's law, the only difference is the “volume” term in Charles's law is interchanged by the “pressure” term in Gay-Lussac's law.
