Answer:
gaseous CO2 bubbles out of the solution
Explanation:
We already know that the dissolution of a gas in water is exothermic. Hence, when the temperature of a solution containing a gas is increased, the solubility of the gas decreases and the gas bubbles out of the solution.
Similarly, the dissolution of KNO3 in water is endothermic. This implies that the solubility of the solid increases with increasing temperature.
Thus the solid becomes more soluble at 75°.
Kinetic energy if it's based on temperature but potential energy is talking in terms of entropy
Answer:
1)non.metals gain electron but metals lose electron.
2)metals are good conductor of heat and electricity but non.meatals are bad conductor of heat and electricity.
3)most of metals are shiny but non .metals are not.
