A solid stays the same shape. The atoms a close together and don't move that much. A liquid can form to any shape, the atoms bounce around a little bit, but not much. A gas has no shape, the atoms are few and far between.
A.) Liquid
B.) Solid
C.) Gas
Answer :
and
Explanation:
According to Boyle's law, it states that pressure is directly proportional to the volume of the gas for a fixed amount of gas and at constant temperature.
The equation given by this law is:

where,
are initial pressure and volume.
are final pressure and volume.
Thus the correct relation for pressure and volume for a fixed amount of gas at constant temperature according to Boyle’s law is
and
Answer: The pressure that is needed is around 405kPa-755kPa
To summarize into 405PPM-755PPM
Explanation: In which 405 PPM-755 PPM which is about the same amount of pressure that water pressurises a car in water or a better example is that it's the same amount of pressure as if a penny was dropped from the sky towards a person holding a square piece of cardboard in which then the penny would directly go straight through the piece of cardboard.
<h3><u>Answer;</u></h3>
-436 kJ/mol
<h3><u>Explanation;</u></h3>
- When two hydrogen atoms approach each other the potential energy of the combination becomes lower and lower until it reaches a minimum value of -436 kl/mol at a distance of 75 pm.
- A covalent bond forms when two or more valance electrons are attracted by the positively charged nuclei of two atoms and thus are shared between both atoms.
