Which instrument would be best for the scientist to use to take a picture of the well-ordered arrangements of he atoms and molecules within a substance?
An electron microscope.
What determines the amount of chemical energy a substance has?
The amount of chemical energy a substance has is determined by the types and arrangement of atoms and molecules in that substance. The energy is stored within the chemical bonds between these atoms and molecules. The strength of these bonds and the potential energy stored in them determine the amount of chemical energy.
A scientist needs to take a picture of the well-ordered arrangements of the atoms and molecules within a substance which of the following instruments would be best for the scientist to use?
An electron microscope.
What kind of energy stored within a chemical substance?
The energy stored my molecules of a compound is called "chemical energy"
What is the origin of the thermal expansion?
As a substance warms up, the molecules within it become more energetic - vibrational, rotational and translational energies increase and the molecules push apart as they are able to exert more force on each other as they bang around faster and harder.

An electron microscope.
The energy associated with the random motion of molecules or atoms within a substance is?
Thermal energy
How do increasing the temperature of a liquid affect the dissolving of a substance?
because you are breaking apart either the dipole bond or hydrogen bond molecules within the substance

The energy is stored within the chemical bonds between these atoms and molecules. The strength of these bonds and the potential energy stored in them determine the amount of chemical energy.
What happens to enthalpy when temperature is decreased?
the atoms (or molecules) within the substance move slower, as temperature decreases.
Which term describes a measurement of the movement of atoms or molecules within an object?
Temperature. When atoms or molecules move faster, the temperature is higher. At Absolute Zero, all movement would stop.
What holds molecules of compounds together?
Within the molecule, covalent bonds hold them together. Between the molecules there can be several different forces. There are dipole-dipole attractions, hydrogen bonds and van der Waals forces. Which of them apply in a particular substance depends on the structure of the molecules.

Which molecules within the nucleus are important in cell reproduction?
The molecules within the nucleus that are important in cell reproduction is DNA .
What is the origin of the thermal expansion?
As a substance warms up, the molecules within it become more energetic - vibrational, rotational and translational energies increase and the molecules push apart as they are able to exert more force on each other as they bang around faster and harder.
What happens when a substance change states?
When a substance changes state, Energy within the substance is gained or lost, but the composition is unchanged.
