in a sugar crystal, the sucrose molecules are arranged in a repeating pattern that extends in all three dimensions, and all of these molecules are attracted to each other by inter-molecular forces that is a type of interaction that binds molecules together and is weaker than the bonds between atoms in a molecule.

the bond between the oxygen and hydrogen atoms (o–h bond) in sugar (sucrose) gives the oxygen a slight negative charge and the hydrogen a slight positive charge.the polar water molecules attract the negative and positive areas on the polar sucrose molecules which makes sucrose dissolve in water.

this is called the mass number of the isotope of the atom.

isotopes are different forms of the same atom. they have the same number of protons   but different number of neutrons.

carbon-12 has mass number   12 as it has 6 protons and 6 neutrons.

carbon-14 has mass number 14 as its has 6 protons and 8 neutrons.

true.

no matter what, the energy given by a substance can act as energy for something else. for example, the energy exerted by wind can be used to power a windmill, which in turn can power a generator that creates electricity. another example can be running water, which generates energy that is used to turn a water turbine, which then generates electricity from the energy that is passing through the turbine.
