Match the following words with their definitions: kinetic energy, diffusion, molecular weight, kinetic molecular theory.1. the process of intermingling atoms (molecules) from one substance into another 2. the energy of motion 3. the sum of the weights of each atom in a formula 4. explains the behavior of gases at the molecular level

1.Diffusion

2.kinetic energy

3.molecular weight

4.kinetic molecular theory

Explanation:

Diffusion simply involves the molecular movement from a region of higher concentration to a region of lower concentration. It is the reason why air freshener sprayed at the end of one room is perceived at the second of the room

Energy is basically of 2 types. The movement energy and the rest energy. Energy that basically concerns the movement of matter is kinetic while the one at rest is potential energy

Molecular weight is the summation of the amu of the constituent elements present in a molecule

The kinetic molecular theory explains the behavior of gases at the molecular level. It contains some set of postulates that helps in predicting gas behaviors at the molecular level

h let me think

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
