Why volume of water decrease at 4 degree centigrade?
When water freezes it sets up a crystal structure which aligns the hydrogen atoms of one molecule with the lone electron pairs on nearby oxygen atoms in other molecules. This arrangement as an optimal distance which determines the density of ice. This packing structure has an 'energy balance' associated with it that is a compromise between the attraction and repulsion of all involved atoms and their configurations with the water molecule. When heat is added to ice the energy of the thermal vibrations of the individual molecules exceeds the repulsion energy between molecules but not their attractive energy. As I said before the packing structure is a balance of many factors and not all these factors have the same energy threshold. Therefore when ice melts it is easier for water to contract (become denser) then it is for it to expand. Once the temperature exceeds 4'C however the thermal energy exceeds all inter-molecular forces and 'ordinary' thermal expansion occurs.
What kind of energy transformation occurs when the energy is converted?
mechanical energy to electrical energy. :)
What energy transformation occurs in a oven?
chemical energy to thermal energy(heat energy)
Which energy transformation occurs first in a coal burning power plant?
which energy transformation occurs first in a coal burning power plant
What name is given to the angle where total internal reflection occurs?
Total internal reflection occurs when the angle of incidence with respect to the normal at the boundary to a less dense medium exceeds the critical angle.
If the excretion of nitrogen balance exceeds the nitrogen intake the condition is called what?
Positive nitrogen balance occurs when the total nitrogen excreted in the urine, feces and sweat is less than the total nitrogen ingested. Positive nitrogen balance must exist for new tissue to be synthesized. When dietary protein intake or total energy intake is inadequate to maintain tissues total nitrogen balance, negative nitrogen balance occurs and new tissue is unable to be synthesized.

When the value of the products that a country imports exceeds the value of the products it exports a what occurs?
An unfavorable balance of trade occurs, whereupon the sky becomes dark and a chill wind sweeps over the country.
When does shortage and surplus occur?
A shortage occurs when quantity demand exceeds quantity supplied. A surplus occurs when quantity supplied exceeds quantity demanded.
What occurs when positive and negative electrical changes build up in the clouds?
Eventually the two charges will have to balance out with what we call lightening?
What occurs when the plasma concentration of a substance exceeds tubular maximum?
The amount of substance that exceeds the tubular maximum will be found in the urine.
What is the connection between spontaneous reactions and free energy?
A reaction occurs spontaneously when free energy is negative, ie the disorder of the system is increasing
Negative nitrogen balance occurs in?
A condition of negative nitrogen is intake of glucocorticoids.
