What is the difference between the first and secong law of thermodynamics?
The first law of thermodynamic show that heat transfer is equal to work.But he does not give the direction as that system is consuming work or doing work. Whereas the second law of thermodynamic give the direction as (1) Heat can flow naturally from high temperature to low temperature.When heat is flowing from high temperature to low temperature he can produce work.(2)Heat can not flow naturally from low temperature to high temperature.for flowing heat from low temperature to high temperature he consume work. Second law of thermodynamic not only give the direction of heat flow but he also show entropy and quality of energy as high grade energy (mechanical work ) and low grade energy (heat).
What is the maximum work obtainable from two bodies at temperatures T1 and T2 . i need derivation. pls help you out?
To obtain the maximum work/time (power) from two bodies at different temperatures, you have to put an "Ideal" Heat Engine between the two bodies. The Heat Engine works with the "Carnot Thermodynamic Cycle". The Heat Efficiency of the Carnot Cycle Engine is called "Carnot Efficiency" and it only depends on the Absolute Temperature of the two bodies. Absolute Temperature also known as Thermodynamic Temperature will be in Rankine degrees, oR, (U.S.C.S.), or Kelvins (I.S.). The Carnot Heat efficiency is given by; eff (%) = [1 - TL/TH] x 100 where TH and TL are the High and Low Thermodynamic Temperatures of the bodies. So if a given Carnot Efficiency turns out be of 35%, this means that from the heat given by the High Temperature body, 35% is converted to work and the rest is dumped to the Low Temperature body.

What scale is used to measure very low temperatures?
Any scale can be used; the absolute, rational, thermodynamic based scale is the Kelvin scale.
How much oral glucose can an emt give?
It depends on the patient. The first thing done is the EMT checks the patients blood sugar, then gives the glucose of the sugar is low. After about five minutes the EMT will recheck the sugar. If it is still to low they would give a second dose.
What is carlsberg's mission statement?

There is virually no risk of contracting HIV if you are caring for someone with HIV?
Generally speaking, the statement is true. If you give injections, clean blood, or do more than normal care, the risk is increased, but still low.
What is PC World Business's mission statement?

Does covalent bonds give water a low heat capacity?
yes it does give a low heat capacity.
How the program statement and code are related?
A statement in your program is part of the code. In a low-level programming language, a statement will map directly to a single CPU instruction. In a high-level programming language, a statement is the smallest element of the language's syntax.
How and can you gather energy just by a light bulbs heat and light?
theoretically you could use the heat from the bulb to drive a thermodynamic cycle. The energy you would be able to generate would be so low, it wouldn't be worth it.
Which statement correctly describes copper?
It has a low resistance and allows charges to move freely.
In a multistage amplifier input impedance is high and output impedance is low justify the statement?
no. input impedance is low & output impedance is high
