Why Cp>Cv ?? |
| Answer» Cp refers to contt pressure and Cv refers to constt volume.When pressure is constt then the heat given to the system is used in two ways:i) in raising the temperature ii)in expansion or in raising the volume.While in constt volume the total heat given to the system is used only in rising the the temperature. Hence Cp>Cv. | |

Work energy theorem... |
|
Answer» Kf-Ki=W [Kf=Final kinetic energy and Ki means initial kinetic energy,therefore,Kf-Ki=change in kinetic energy and it is equal to the work done;(W)]. Net work done on body = change in kinetic energy According to the work-energy theorem, the net work on an object causes a change in the kinetic energy of the object. The formula for net work is net work = change in kinetic energy = final kinetic energy - initial kinetic energy. |

Why rain drops are sperical in shape |
|
Answer» Due to surface tension , liquid try to minimize its surface area so rain drops are spherical Surface tension also plays important role in this phenomenon It is due to the teason that when the rain drops fall on the earth\'s surface then due to the gravitational force of the earth the drop feels a force acting downwatds and changes its position and a pointed closening on the outer surface(????) Raindrops start to form in a roughly spherical structure due to the surface tension of water. This surface tension is the "skin" of a body of water that makes the molecules stick together. The cause is the weak hydrogen bonds that occur between water molecules. reason is surface tension not viscosity Due to surface tension Due to Viscosity |
