Air is mainly composed of N2 (78%), O2 (21%) and other trace gases. Now, the total pressure of air is the sum of the partial pressures of the constituent gases. The partial pressure of each gas, for example say O2, can be expressed as:
p(O2) = mole fraction of O2 * P(total, air) ----(1)
Thus, the partial pressure is directly proportional to the total pressure. If we consider a sealed container then, as the temperature of air increases so will its pressure. Based on equation (1) an increase in the pressure of air should also increase the partial pressure of oxygen.
In general, solubility increases with temperature. When you increase the temperature of a solvent, you increase the kinetic energy (or energy of movement) of the molecules, and this greater energy helps dissolve more of the solute molecules.
Answer:
Double replacement is the answer
The correct answer is option C, that is, the universal law of gravitation.
According to Newton's law of universal gravitation, every particle fascinates every other particle in the universe with a force that is directly equivalent to the product of their masses and inversely proportional to the square of the distance between their centers. This is a usual physical law obtained from empirical observations by what Isaac Newton knew as inductive reasoning.
Answer:
c
Explanation:
because forces act on an object and make it change direction based upon strength hope this helps.
