Question

Read the passage. Oceans and seas can act as a buffer heat reservoir to regulate climates. They can absorb great quantities of heat in the summer, with very little temperature change. In the winter, oceans and seas release the heat. This is the main reason why coastal climates are milder compared to terrestrial climates. Which choice correctly explains this phenomena? A) the high freezing point of water caused by the strength of O–H bonds B) the high boiling point or water caused by hydrogen bonding C) the high heat of vaporization of water caused by the strength of O–H bonds D) the high specific heat of water caused by hydrogen bonding

Answer 1

Answer:

D) the high specific heat of water caused by hydrogen bonding

Explanation:

• The water has a higher specific heat and is due to the bonding of H2 molecules by the water. When the bonding is broken the heat is released and water molecules can move freely.  

• This leads to a decline in the temperatures and thus the heat is released in winters and coastal climates are considered to be milder than terrestrial climates. As the energy is released on condensation.
