Question

Why does methanol show an exothermic reaction with water at room temperature while it gives an endothermic reaction with water in cold conditions?

Answer 1

there are three primary phases of matter: solid liquid and gas. a solid becoming liquid is melting or fusion. a solid becoming gaseous is called sublimation. eloquent becoming solid is called freezing. a liquid changing to gas is called boiling or evaporation. a gas changing into solid is called the position and the gas changing into a liquid is called condensation. half of these are endothermic meaning the observed from their surroundings. the others are exothermic meaning their release heat
