Answer:
PV ∝ T
Explanation:
Charles’ law states that, at constant pressure, volume is proportional to
temperature. Gay-Lussac’s law states that, at constant volume, pressure is proportional to
temperature. Therefore, the product of pressure and volume is proportional to temperature.
This is also consistent with Boyle’s law, which states that pressure is inversely proportional
to volume when temperature is constant

Answer:
495 J
Explanation:
When the hot pot was set on the counter to cool, heat energy was lost from the pot. Note that according to the first law of thermodynamics, heat is neither created nor destroyed.
This implies that, the heat energy lost from the pot must be gained by the surrounding air. Therefore, if 495 J of energy is lost from the pot, then 495 J of energy is gained by the surrounding air.
crystallization is a process which helps to separate a pure solid from a solution in its crystal form. This is the in use to purify solid. For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities.
Sugar and salt are examples of products where crystallization does not only serve as separation/purification technique, but where it is also responsible for getting crystals with the right size (and shape) for further application of the products.

Answer:
Explanation:
Shifting, labor intensive and monoculture are different in terms of description,restrictions and problem.
Shifting is an agriculture method in which an area if land is cultivated for a while and abandoned for the soil to regain and preserve it's fertility. It is done to restore soul fertility.
It has restrictions because it is done in places where there is large areas of land, if there is not large area of land, it will be done.
It can lead to defforestation because trees are cut fine for land cultivation and after a while the land is abandoned and trees are cut down some where else too.
Labor intensive refers to agricultural industry requiring or needing large amount of labor to produce agricultural products. Labor intensive is restricted to areas where there is low or no people who can engage in agricultural services.
Labor intensive require high skilled people which might not be available.
Monoculture is a farming system where by a single crop is cultivated in an area of land.
The problem of monoculture is that it displaces species and nutrients occuring naturally in an ecosystem.
Monoculture is restricted in areas where diversity of crops are needed.
