Alternative Form of Decay Equation in Terms of Half – Life Time

Alternative Form of Decay Equation in Terms of Half – Life Time Half – Life Time is defined as the time duration in which half of the total number of nuclei will decay or be left un-decayed. Say, for example, at any instant if we look into the quantity of a sample of radioactive element, Read more about Alternative Form of Decay Equation in Terms of Half – Life Time[…]

Relation between Object and Image Velocity

Relation between Object and Image Velocity An image is the point of convergence or apparent point of divergence of rays after they interact with a given optical element. An object provides rays that will be incident on an optical element. The optical element reflects or refracts the incident light rays which then meet at a Read more about Relation between Object and Image Velocity[…]

Efficiency of Carnot Cycle

Efficiency of Carnot Cycle A heat engine is a device that produces motion from heat and includes gasoline engines and steam engines. These devices vary in efficiency. The Carnot Cycle describes the most efficient possible heat engine, involving two isothermal processes and two adiabatic processes. It is the most efficient heat engine that is possible Read more about Efficiency of Carnot Cycle[…]

Relation between Pressure and Volume during an Adiabatic Process

Relation between Pressure and Volume during an Adiabatic Process When a thermodynamic system undergoes a change in such a way that no exchange of heat takes place between system and surroundings, the process is known as adiabatic process. In this process Pressure (P), Volume (V) and Temperature (T) changes but ΔQ = 0. Let, n Read more about Relation between Pressure and Volume during an Adiabatic Process[…]
