zeroth law of thermodynamics

zeroth law of thermodynamics

Zeroth law of thermodynamics:- This law states that when two bodies are in thermal equilibrium with a third body, they are also in thermal equilibrium with each other. If an object with a higher temperature comes in contact with an object of lower temperature, it will transfer heat to the lower temperature object. The objects […]

First Law of Thermodynamics

First Law of Thermodynamics:- This law states that the heat and mechanical work are mutually convertible. According to this law, a definite amount of mechanical work is needed to produce a definite amount of heat and vice versa. This law also states that the energy can neither be created nor be destroyed, through it can […]

Welding process Terminology

Welding is a process in which localized coalescence (permanent joint) is produced by heating the material upto suitable temperature with or without application of filler material. If the filler material is of same material as base material then the welding is Homogeneous welding, if filler material is different from the base material then the welding […]
