Why do opaque materials become warmer when light shines on them?
You must have Mr. Williams.
What happens to kinetic energy of the particles of a substance as the substance changes from a liquid to a gas?
The faster the molecules of a substance are moving, the warmer that substance is, because temperature is really a measurement of the average kinetic energy of the molecules in a substance or object. For a substance to evaporate, or change from a liquid to a gas, it has to become warmer. That means that the kinetic energy of the molecules increases.
What is the difference between matter changes and chemical changes?
Matter changes is to make a matter for example water to change form, and when it becomes steam it means you achieved a matter change.Everything has molecules that move so to change the matter you must make the molecules start moving in a different way. You achieved that with heat as you know heat has this property. Chemical change is to mix two chemicals that will form a new product with equal mass, and that's the chemical change ;o)
These molecules must form in order for life to exist?
There are quite a few molecules that must form for life to exist. One of these life-supporting molecules is water.
Are air is weightless?
Air has weight because it is made up of molecules of matter and all matter has weight and mass.
What must molecules do for. Matter to become warmer?
move faster.
What must molecules do matter to become warmer?
move faster.
What must molecules do for matter to become warm?
They move faster & faster

Why do all states of matter have molecules?
All states of matter do not necessarily have molecules. The noble gases consist of individual atoms, and ionic compounds consist of ions, or formula units. All states of matter must contain atoms, molecules, or ions, because matter is made of atoms, molecules, and ions.

What are small molecules that must combine with large proteins to become immunogenic?
hapten
Is smell matter?
Yes it is matter. Since the receptors in your nose only respond to molecules, the "smell" of perfume must be matter in order to activate these receptors. The liquid in perfume is atomized by the pump, physically separating the molecules. The "smell" that you are sensing is the vaporization of aromatic organic molecules from the liquid.
Why does a coin become warmer when it is struck by a hammer?
A coin will get warmer when struck by a hammer just like a nail will. The energy of the hammer blow is converted into heat. The atoms and molecules in the coin will be compressed a great deal by the hammer blow, and this will break metallic crystal bonds in the metal matrix. This creates heat. The energy of the hammer blow must be conserved, and heat is a large part of the equation.
How do scientists define matter?
Matter must have mass and volume, and occupy space. There are things like light and sound that are said to have no matter.
Why must refrigerant in the suction line be slightly warmer than the saturation temperature?
why must refrigerant in the suction line be slightly warmer than the saturation temperture
What must occur for condensation to occur?
The air must be warmer than what it is touching and there must be moisture in the air.
