Why is ice the solid form of water? Why does water expand when frozen? What happens to molecules during evaporation? What happens to runoff water? What happens to water that does not percolate? What happens when carbon is heated? How did the ice age affect the Earth?
An increase in temperature will affect vapor pressure by: (a) decreasing the density of the gas molecules, making them lighter and easier to move around (b) increasing the average kinetic energy of the molecules, making them move faster and collide more ( What ...
Denaturation ("changing the nature") happenswhen protein molecules unravel from their naturally coiled state. With eggs, this happens most frequently when they're heated or beaten, but denaturation can also be prompted by salt, acids (such as vinegar), alkalies (such as baking soda), and free...
Less expensive than annealing,quenchingis a heat treatment method that quickly returns metal to room temperature after it is heated above its upper critical temperature. The quenching process stops the cooling process from altering the metal's microstructure. Quenching, which can be done with water, ...
When ice is warmed, the water molecules forming its structure vibrate more and more vigorously until finally the forces between them are no longer strong enough to hold them together – the ice melts and turns into liquid water. Quantum physics predicts that similar phenomena can be observed if...

As the temperature rises, more microstates become accessible, allowing thermal energy to be more widely dispersed. This is reflected in the gradual increase of entropy with temperature. The molecules of solids, liquids, and gases have increasingly greater freedom to move around, facilitating the spr...
change. Since the temperature of the system changes, density, as well as the heat, changes in the system. It is also defined as randomness in the system. When the water is heated, the temperature increases, which increases the entropy. Well, enough of Physics. The questions that pop up ...

rises. The state of the substance may shift from solid to liquid or liquid to gas. When heated, the material expands. When a substance is cooled, or when heat is removed from it, the molecules lose heat and the temperature drops. This page explains all these effects caused due to heat....
