How heating a substance affect that substance?
Heating a substance can result in a chemical reaction, which usually results in a simple combustion reaction. This is because Oxygen, or O2, is added to the substance, which can dramatically alter the substance.
Does a solid dissolve faster when you stir the solution?
Yes. This is due to the movement of the molecules. As you stir the solution, there is more kinetic energy. The more kinetic energy something has, the more heat is produced, which causes a substance to dissolve faster. In addition, stirring causes the substance to be exposed to more surface area.
Why does diffusion become faster on heating?
because By Heating Their Kinetic Energy is increased. And due to kinetic energy they moves faster..
Why does heating a substance causes molecules to expand?
There is the Kinetic theory of matter. All matter is made up of atoms and molecules that are constantly moving.When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.Mass of the object remains the same, however. Solids, liquids and gases all expand when heat is added. When heat leaves all substances, the molecules vibrate slower. The atoms can get closer which results in the matter contracting. Again, the mass is not changed.Best regards, Aleh Aprelenka
Why do solids expand on heating?
That's because the molecules or atoms move faster, and in general have more energy.That's because the molecules or atoms move faster, and in general have more energy.That's because the molecules or atoms move faster, and in general have more energy.That's because the molecules or atoms move faster, and in general have more energy.
How does heating acid make metal dissovle faster?
Heating a substance causes the molecules within it to move more quickly. So imagine that every surface atom of the metal reacted with acid: the faster the reacted material can move away from the unreacted metal, the faster new acid molecules can get close enough to the metal to react.
How does the pressure and temperature of each air mass change?
Temperature is really just the amount of kinetic energy in the molecules of a substance. If you add more energy by heating the substance then the molecules dash about faster and faster. This increases the pressure if the substance is constrained, like gas in a jar or in a bomb.

Do the particles of a substance move faster or slower as the substance?
With the help of heating the movement is faster.
Why does heating increase the speed at which a solute dissolve in water?
It makes the water molecules move faster.
Why couldn't you keep a substance from freezing by shaking its molecules?
The faster the molecules move the faster the substance is going to freeze. Sounds crazy, but it's true.

What happens to the molecules of a substance when it is melted?
the molecules vibrate, faster and faster as the heat increases then they become disordered
What are the three things you can do to get a substance to dissolve quicker?
Heating causes an increase in speed of dissolving as does stirring faster. In addition, crushing to a fine powder (smaller particle size) increases the surface area to volume ration and helps the substance to dissolve faster.
What happens to the water molecules as they start to heat up?
Heating water molecules causes them to move faster and faster. Water when cool is in a way (sticky). When heated the water molecules are moving far too quickly stick together. The heated water molecules become less dense and may stick to air molecules. Floating into and combining with the atmosphere.

Yes. This is due to the movement of the molecules. As you stir the solution, there is more kinetic energy. The more kinetic energy something has, the more heat is produced, which causes a substance to dissolve faster. In addition, stirring causes the substance to be exposed to more surface area.
