What is bernauli theorm |
|
Answer» when a liquid flow from one place to another place in streamed line motion then the every points in its path the sum of pressure(p)k.eand p.e per unit volume remain constant The sum of kinetic energy, potential energy and pressure energy remains same in the uneven area of cross section tube Total energy possessed by liquid in equilibrium is constant It states that ,if the velocity of a fluid increases then the pressure of that fluid decreases. It is nothing but the conservation of energy. |

How to identify that in which case we have adiabatic change and in which isothermal |
| Answer» Isothermal process is that process in which temperature is constant although the change in heat energy is taking place.Since temperature is constant so change in temperature is 0So all the energy absorb is used in doing work so system expands.Where as in adiabatic process the exchange of energy between system and surrounding doesn\'t take place so dQ =0 So system uses its own internal energy to do work And we know dQ= dU +WdQ=0So dU= -WIf system expands i.e.work is positive so internal energy is decreasesIf system contracts so work done is negative and internal energy increases | |
