Question

of these three states of matter: solid, liquid, and gas, gases are the only state that have a definite shape have mass are highly compressible question 11 1 pt in which state of matter do the particles have the most energy? solid gas liquid particles do not have energy question 12 1 pts true or false: elements in groups 18 called noble gases are highly reactive, because they have 1 valence electron. true false

Explanation:

• For the first question, solids have a definite shape, all states of matter have mass, and gases are highly compressible due to large intermolecular spaces.
• For the second question, gas - phase particles have the most energy as they move freely and rapidly compared to solids and liquids.
• For the third question, noble gases in group 18 have a full valence shell (8 electrons except for helium which has 2), making them very stable and unreactive.

Answer:

• First question: are highly compressible
• Second question: gas
• Third question: False
