Detailed explanation-1: -Cohesion and hydrogen bonding are the cause for water’s low vapor pressure, high boiling point, and high heat capacity. Adhesion is water’s property to adhere to a surface, and is the cause of capillary action.
Detailed explanation-2: -Water’s high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely.
Detailed explanation-3: -Which of the following is responsible for water’s high heat capacity, high surface tension, strong cohesion, and strong adhesion properties? a hydrogen ion.
Detailed explanation-4: -Water’s high surface tension is due to the hydrogen bonding in water molecules. Water also has an exceptionally high heat of vaporization. Vaporization occurs when a liquid changes to a gas, which makes it an endothermic reaction.
Detailed explanation-5: -The high surface tension of water is caused by strong molecular interactions. The surface tension arises due to cohesive interactions between the molecules in the liquid. At the bulk of the liquid, the molecules have neighboring molecules on each side.
