A substance that gives off heat when dissolving in water will
have greater solubility at low temperatures. According to Le Chatelier's
Principle - if heat is a product of the reaction, increasing the
temperature will drive the reaction backwards.
It does increase. The temperature is increased, so more solute particles will dissolve. This occurs because as the temperature increases, the intermolecular forces can be more easily broken, allowing more of the solute particles to be attracted to the solvent particles.
It is because the soulubility is changed physically. In actuality the solubility of na2so4 increases but as temp increases the solubity aslo decreases. So really it is like the solubility of the chemical decreases more during the thermal increse than the increase of solubility.
I believe (I may be wrong) because it's a gas.
because it releases heat when dissolving. cooler T favors the process
As the temperature increases:The solubility of a solid in a liquid increasesThe solubility of a liquid in a liquid increasesThe solubility of a gas in a liquid decreases(The solubility of liquids and solids increase as temperature increases, while the solubility of gases decreases as temperature increases.)
Perhaps you mean the solubility of substances in water. Most solids have increasing solubility in water with increase in temperature, but certainly not all of them. Some solids e.g. Cerium Sulphate have decreased solubility in water at higher temperatures, while some solids show increasing solubility up to a certain temperature, above which the solubility decreases, such as Sodium Sulphate. The solubility of common salt, Sodium Chloride, is almost unaffected by temperature. Gases generally have lower solubility in water at higher temperatures.
On heating water from O0c to 4oc the volume of water decreases while that of wax increases.
Apparent solubility represents the solubility one observed during the experiment while the intrinsic solubility meant to the real or true solubility.
The oxidation state of one atom increases while another decreases.
we know that the salt nacl is formed from two competly disaccosiating acid , base ie hcl and naoh while in case of na2so4 naoh plus h2so4 weaker comparitively to hcl shows daviation

the solubility of a solid increases with temperature while those of gasesdecrease with rise in temperature.
because the carbonated of group 1A is stable while the carbonates of group 2A is not stable .....

increases, decreases

This relationship is most often observed when dealing with liquid solutions. The solubility of solids and liquids in a liquid solvent tends to improve as the solvent's temperature increases, while the solubility of gases in the same type of solvent generally decreases as its temperature rises.
increases; decreases
if the speed increases the frequency increases if the speed decrease the frequency decreases
Assets has debit balance as normal balance so debit balance increases it while credit balance decreases it.
