They are different substances because in the weight and size, they are different.
in weight gas weighs nothing but every solid is different.
same with liquids.
It is possible that this water is formed, at least partially, by deliquescence of salts, a process during which hygroscopic salts absorb water vapor from the atmosphere and form a saturated liquid brine. ... Potassium compounds such as KCl, K2SO4, and KNO3 are salts resulting from biomass burning.
thus k2so4 is a deliquescent salt
The enthalpy difference between the reactants and the products is equal to the amount of energy absorbed from the surroundings. A reaction in which energy is absorbed from the surroundings is called an endothermic reaction. ... Exothermic reactions heat up their surroundings while endothermic reactions cool them down.
I believe it’s 6km/ south
