PROPERTIES OF WATER

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
On a hot summer day, a fish in a shallow pond does not experience a spike in temperature and does not lose its habitat to evaporation. What properties of water are at work to provide these protections?
A
High heat capacity and high surface tension
B
Strong cohesive properties and high heat of vapoourisation
C
Strong adhesive properties and high heat capacity
D
High heat capacity and high heat of vapourisation
Explanation: 

Detailed explanation-1: -The hydrogen bonds between water molecules cause the water to have a high heat capacity, meaning it takes a lot of added heat to raise its temperature. As the temperature rises, the hydrogen bonds between water continually break and form anew.

Detailed explanation-2: -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-3: -How is water involved in the synthesis of a triglyceride compared to its involvement in the synthesis of a disaccharide? Both produce water as a product, but more water is produced per triglyceride molecule than per disaccharide molecule.

Detailed explanation-4: -Common disaccharides include lactose, maltose, and sucrose. Lactose is a disaccharide consisting of the monomers glucose and galactose. It is found naturally in milk. Maltose, or malt sugar, is a disaccharide formed by a dehydration reaction between two glucose molecules.
