It depends on experiment or observations it may increase, 1- kinetic energy of molecules, 2- number of collisions among molecules per unit time, 3- solubility of a substance in water, 4- rate of evaporation of a liquid, 5-rate of a reaction and several other factors.
rate of solution
The movement of molecules and collisions are increased at high temperature.
would molarity increase, decrease, or stay the same if the room temperature increased by 5 degrees centigrade
increased precipitation
If the heat is increased, the increased temperature of the solvent will increase the solubility of the solute.
The motion of chemical entities increase with the temperature and the probability of collisions also increase.
The rate of most will also increase.
No, the solubility of BaSO4 does not significantly increase as the temperature of the solution is increased. BaSO4 is sparingly soluble in water and its solubility is largely unaffected by changes in temperature.
Generally the speed of reaction increase when the temperature is increased.
Increased pressure and or temperature.
yes
When temperature is increased the amount of molecules evaporated is increasef and as a consequence condensation is also increased so vapour pressure increases.
