What else can I help you with?
What must the components of a solution have different in order for distillation to work?
Volatility, vapour pressure
Will mercury vapour work in a sodium vapour fixture?
no
How does vapour compression work?
See my answer to~How does air conditiong work~ on this site.
Why is superheated steam used in power plant?
because if the steam is not superheated the remaining water droplets reduce efficiency and can cause corrosion and pitting. +++ Nearly! Saturated steam, as non-superheated steam is called, is really only steam at the pressure and temperature in the boiler. Once it starts to expand as a gas in doing its work, the pressure and temperature fall and condensation will set in, leaving less and less useful water-vapour to act as a gas. Hence, as you say, the efficiency falls.
If punctured which hose would empty a scuba tank at a faster rate high pressure hose or low pressure hose?
LOW PRESSURE HOSE: Yes, a low pressure hose. A high pressure hose has a very small diameter opening since it is just used to measure pressure and it is not performing any work. A low pressure hose is used to perform work and has a larger diameter opening so air can move through it.
What is the equation for work in terms of pressure and volume?
The equation for work in terms of pressure and volume is: Work Pressure x Change in Volume.
Why does water evaporate below its boiling point?
The molecules in a liquid are always moving. As the temperature of the liquid increases the molecules have more energy and move faster. The molecules bump into each other making some move yet faster. Occasionally one of the fast moving molecules near the surface breaks through the surface and becomes airborne causing this molecule to leave the liquid. As this happens more and more molecules leave liquid and enter the air. This is evaporation.
What is measurement for millibar?
1 Bar is 1 atmosphere of pressure. Much used in very high pressure work. 1 Bar is approx 1kg/cm2
What is a CO cartridge and how does it work?
A CO, or carbon dioxide, cartridge is basically a container of carbon dioxide under pressure. When the canister is punctured, it releases the pressure inside and the force is used to create air pressure. These are commonly used in paintball gun.
What is the effect of decreased pressure on the boiling and freezing point?
As pressure decreases, the boiling point of water will also decrease. Backpackers camping in the high mountains are familiar with the phenomena when they get water boiling - and find that it is still only lukewarm because the atmospheric pressure at their high altitude is so low.
What willbe the expression for the work of cohesion between water and benzene?
Water and benzene will have a work of adhesion rather than a work of cohesion as this is the work associated with the connection between two things as opposed to cohesion which is the force holding one thing together. The expression for the work of adhesion is: gamma of the liquid vapour interface + gamma of solid vapour interface - gamma of solid liquid interface. Where gamma is surface tension.
How do you work out pressure?
Force / area = pressure
