We all struggle in some subjects, you do badly when you don't try, and sometimes we try and can't get the answer, I'll help with that. :)
The first answer is CO2(g), CO2 is a gas, and all gas have... 4) No definite shape, no definite volume.
A piece of ice, a block of wood, and a ceramic cup are solids. They have shapes that do not change and volumes that can be measured. Any matter that is a solid has a definite shape and a definite volume.
A liquid takes the shape of what holds it, besides a flat surface, which will just evidently, take the shape of a flat surface. A liquid has a definite volume, because the volume of a liquid is constant because forces of attraction keep the particles loosely together.
Gases attempt to fill a container of any shape or size. Therefore, it has no definite shape.
There are forces of attraction among the particles in all matter, therefore, it has no definite volume.
The second question might become easier with the explanation above. A liquid has a definite volume because the forces of attraction are loosely together! Therefore, it has a definite volume, but it will take the shape of it's container.
This means... Yes! 2) It retains its original volume but changes shape.
This one is easy. To convert one gram of a solid at its normal heating point to a liquid at the same temperature, is the 1) Heat of Vaporization.
Heat of Vaporization is the amount of heat energy required to convert one gram of a substance from a liquid to a gas.
The third question, the molecules for H20, in a solid phase are always in an geometric and arranged pattern.
Most solids are arranged in geometric and arranged patterns, and since H20 is not in its indefinitely shaped liquid phase, it has a definite shape and thus, retains a repeating (geometric) pattern.
(Note- Some solids like wax or rubber do not have an arranged or geometric pattern.)
The “average of a kinetic energy” is defined as the vitality of movement of particles of a framework.
Or in simpler terms, “energy motion”.
So when temperature increases, the average kinetic energy of a molecule(s) 1) increases.
The major visible difference between<span> the two are crystal size, </span>intrusive rocks<span> have a larger crystal/grain texture due to the slow cooling of magma below the earth surface which encourages the growth of larger crystals, while </span>extrusive rocks<span>, because of the rapid cooling at/above the earth's surface does the opposite. Hope I helped</span>
There are four type of intermolecular forces: ionic, dipole-dipole, hydrogen bonds and London disperssion forces.
CH4 have no ions, so there are not ionic forces.
CH4 is a symetrical molecule, so there cannot be a net dipole in the molecule, so there is not dipole-dipole interaction.
Hydrogen bonding is only possbile when H is bonded to N, O or F, beacuse they are the atoms that considerable higher electgronegativy than hydrogen.
So, the only intermolecular force present in CH4 molecules is London disperssion forces, which is a force present in any molecule and is the weakiest one. That explains the low melting and boiling points of CH4.
The terms of a equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity
Because a copper ion looses electrons, meaning it's negatively charged, and positives and negatives attract.
