Solubility is the amount of solute that can dissolve in a given solvent at a specified temperature or pressure. Therefore, solubility is affected by pressure and temperature such that increase in temperature increases the rate of solubility of substances. In additional solubility depends on the molecular size of the solute such that when other factors are kept constant then a solute with small particles will dissolve more faster. Therefore, to increase the rate of solubility Ryan may; increase the temperature of water.
Answer:
Radiation and conduction
Explanation:
The human body lose heat by these two ways, because everything that touches our bodies and is in a temperature below us will receive part of our heat (conduction), and you can figure out that we lose heat by radiation because a human bright in a heat cam
Not 100% if this answers however:
The radium nucleus turns into radon-222 nucleus, itself radioactive, containing two protons and two neutrons less. The disintegration releases 4.6 million electronvolts of energy. The alpha particle carries the 222/226ths of this available energy and the radon 4/226ths.
The average kinetic energy of a mole of substance is determined from the formula, E=1.5RT where R is 8.314 J/mol K. Substituting temperature of zero kelvin to the equation, the energy is zero. It is recalled that at zero kelvin or absolute zero temperature, all molecules are not moving.
The answer is B,This is an example of convection, where fluid will circulate.This is because when part of air is warmed up, they expand and become less dense then rise,Therefore, the colder air contracts and become denser and sinks, in order to take in the place of the warm air. This phrase circulates and therefore the it can transfer heat a lot more faster.
