The four classical phase changes in matter depend on pressure and temperature. Solids need the lowest amount of pressure and temperature, followed by liquid, then gas, then plasma needing the most. (There are other non-classical states of matter eg. superfluids) The amount of temperature and pressure (or just enthalpy) required to make the phase change depends on the molecular structure of the molecules.
No matter what size a sample is, if is hard, it will still be just as hard. This means that hardness is an intensive properties. Intensive properties do not matter what size of sample is being used. Extensive properties will change if sample size is changed.
Density is an intrinsic property, not an extensive property of matter. This is because it DOES NOT depend on the size of the sample (amount). The density of a small piece of matter is the same as the density of a larger piece of that same matter.
Yes, leaves are a sample of matter. Matter is anything that has mass and takes up space. Leaves are composed of atoms and molecules, making them a form of matter.
Adding heat to a sample of matter increases the kinetic energy of its particles, causing them to move faster and collide more frequently. This increased movement can lead to changes in the physical state of the matter, such as melting or vaporization, depending on the amount of heat added.
The property that depends on the size of the sample is extensive. Extensive properties, such as mass and energy, scale with the size of the sample. This means that as the sample size increases, the value of the property also increases proportionally.
An extensive property. Examples include mass and volume, which vary based on the quantity of matter present in a substance.
Yes!
Taxes on cars are a matter of state and local law. It would depend on the state and locality.
The density, and valence of an element do not depend on the amount.
Gravitational lensing does not depend on a the state of matter of light, rather it is an expression of the geometric curvature of space/time due to mass.
Mostly temperature.
A property is what characteristics something has.
No, a change of state does not affect the amount of matter in a sample of water. When water changes from solid to liquid (melting) or from liquid to gas (evaporation), the total mass remains constant, as mass is conserved during these transformations. The molecules of water simply rearrange themselves, but no matter is lost or gained in the process.
No matter what size a sample is, if is hard, it will still be just as hard. This means that hardness is an intensive properties. Intensive properties do not matter what size of sample is being used. Extensive properties will change if sample size is changed.
The different between intensive properties and extensive properties is that one is depend on the amount of matter present and one is do not depend on the amount of matter of present.
Potential energy is calculated as mass x gravity x height. Gravity is 9.8 meters per second square.
Mass is an extensive property, which depends only on the amount of matter in the sample, not on the composition of the sample.
