Specific gravity is an intensive property. It does not depend on the amount of the substance present and remains constant regardless of the size of the sample.
If by solidity is meant density then yes - the denser is the matter the object is made of, the more matter there is in a cube of its volume, the more its mass, so the more its gravity. The gravity of two objects towards each other is proportional to their masses and inversely proportional to the distance between them.
Factors that affect the changes of matter include temperature, pressure, and the presence of catalysts. Changes in these factors can lead to physical changes, such as melting or boiling, as well as chemical changes, such as reactions that form new substances. The composition and properties of the matter can also influence how it changes under different conditions.
Gravity is affected by the masses of the objects, and the distance between them (really the distance between their centers). Greater mass increases the force of gravity. Greater distance decreases the force of gravity.
The amount of energy needed to change the "state of matter" is termed as "latent heat". This is not same for vapourisation (liquid to vapour) or for fusion (solid to liquid). For example, latent of fusion is 79.7 cal whereas latent heat for vapourisation is 541 calories. The latent depends on how closely the atoms and molecules in the matter are closely packed.
Yes.
Gravity is a force between any two masses.
The same as the specific gravity for copper which is 8930. It doesn't matter what shape the copper is made into... it still has the same specific gravity.
Density aka specific gravity is a measure of the amount of matter in a given volume. Actually specific gravity is not the measure of the amount of matter in a given value, it is a comparison of the density of the substance to water's density. Specific gravity is a unitless quantity.
No. Mass (e.g. grams) is a measure of matter, and is independent of gravity. Weight (e.g. pounds) is a measure of force and is directly related to gravity.
Sorry, but earth is not a gravity free system. No matter where it is placed in the universe it will still have gravity that will affect all around it and that upon it.
Any two objects attract one another.
Gravity is NOT matter, it is a force that effects matter.
Specific gravity is an intensive property. It does not depend on the amount of the substance present and remains constant regardless of the size of the sample.
The most important effect of gravity in hockey is that it keeps the ball on or close to the ground. For that matter it also keeps the players on the ground.
Factors that affect changes in matter include temperature, pressure, and the presence of catalysts. Changes can also be influenced by the amount of reactants present, the surface area of the substances involved, and the concentration of the substances. Additionally, the type of chemical bonds in the substances can determine how easily they undergo changes.
Gravity is not unique to the Earth. All matter has gravity and all matter attracts all other matter. Since the Earth has mass it also has a gracvitational field associated with it.
