Water at 150 kPa is contained in a 300 L tank.At this state (state 1), 95% of the volume isoccupied by saturated vapour. Heat istransferred to the water thereby raising itspressure and temperature until state 2 isreached. At a pressure of P2 = 3 MPa a safety valve opens and vapour flows out. The processcontinues, maintaining a 3 MPa internalpressure until 73% of the mass in the tank is avapour, then the valve closes (state 3).Determine the following:
a) Total mass that flowed out, me [kg]
b) Total heat transfer, 1Q3 [J] (state 1 to state 3).
A water solution have 64% Na 2 S 2 O 2 together with 1.0% soluble impurity. Upon cooling to 5°C, Na 2 S 2 O 2 ·5H 2 O. crystallizes out. The solubility of this hydrate is 1.35
Van der Waals repulsions Because severe van der Waals repulsions occur among the tert-butyl groups in compound A at normal bond lengths and angles, the only way for the molecu
Explain the Gibbs Phase Rule for Multicomponent Systems? The Gibbs phase rule for a pure substance was written F = 3 - P. We now consider a system of more than one substance an

How will do project work on purification of organic compounds by crystalization and distillation from water and alcohol?
Cavitation occurs when the pressure in localized regions reaches the vapor pressure. This can cause actually cause structural damage if vapor bubbles form and burst. Consider a sys
Q. What are the Chemical Properties of Halogens? Ans. he halogens have 7 valence electrons in their outermost shell. Note that 7 is one electron short of the octet.
Q. Explain laws of Electrolysis? Ans . A spontaneous reaction takes place by itself. Some redox reactions are not spontaneous. In a no n-spontaneous redox reaction ,
