Since molecules are particles of matter, it takes energy to move them. Heat is a form of energy. It causes molecules to bounce into each other separating them. As molecules separate, their density, the amount of matter found in a given volume or space, decreases. Air that is heated will rise, therefore, because the gravitational force of the earth on the heated molecules is less than it was on the higher density collection of molecules.
Therefore the molecules will spread and become partially flowful- Like the molecules in liquid.
They vibrate or move around vigorously depending on their state of matter. If there is enough heat, the intermolecular bonds can break into smaller molecules or separated atoms.
And when you cool molecules to 0 degrees Kelvin, you reach Absolute Zero, a point in which the molecules don't move at all.
When ethanol is heated in the presence of concentrated H2SO4, it undergoes dehydration to form ethylene gas. This reaction follows an elimination mechanism where a water molecule is eliminated from ethanol to produce ethylene.
Zinc carbonate decomposes when heated to give zinc oxide.
When ice is heated, it absorbs heat energy and melts into liquid water. The temperature of the ice remains at 0 degrees Celsius until it has completely melted.
Generally, the density of solids, liquids, and gases decreases as they are heated. When heated, the particles in these substances gain energy and move more, causing the substance to expand, which leads to a decrease in density.
When antifreeze is heated, it changes from a liquid to a gas. This process is known as vaporization. If antifreeze is heated beyond its boiling point, it can produce harmful vapors and potentially lead to a dangerous situation due to the toxicity of the chemicals in antifreeze.
Then that molecule will escape the surface of the liquid and become a molecule of gas. This is the process by which water slowly evaporates even when not heated.
When matter is heated it will expand
no answer
When gas is heated then its molecule get energy and start to move faster.
When ethanol is heated in the presence of concentrated H2SO4, it undergoes dehydration to form ethylene gas. This reaction follows an elimination mechanism where a water molecule is eliminated from ethanol to produce ethylene.
When an enzyme is heated it is denatured, which means that it can no longer function.
Ozone when heated gets decomposed. It decomposes into oxygen.
nothing
It cooks.
it will evaporate
Water IS a polar molecule.
