Detailed explanation-1: -Water has a high specific heat which means it will take a long time to heat up. The high specific heat of is because water is from its tight bonding structure.

Detailed explanation-2: -Water has a particularly high heat capacity The specific heat capacity of a substance is the energy needed to raise 1 Kg of a substance by 1°C (or by 1 Kelvin). Liquid water has an especially high heat capacity, 4184 J/Kg K.

Detailed explanation-3: -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. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.

Detailed explanation-4: -The specific heat capacity of dry pasta is 1.8 J/(g· C).

Detailed explanation-5: -Reason 1. A large volume of water has a higher thermal mass, and thus keeps its temperature better than a small volume. When you drop pasta into it, it thus re-achieves a boil much faster. If you were to let the pasta sit in lukewarm water as it comes back up to temperature, it would be overcooked and mushy.
