Which statement about water is false?
A. Water helps to prevent dramatic changes in body temperature because it has a high heat capacity.
B. Sweating cools the body because water has a high heat of vaporization.
C. Not counting bones, water makes up about 70% of the weight of a human body.
D. During a condensation reaction, the addition of water breaks a polymer into monomers.
E. Polar molecules are attracted to water.

Respuesta :

Answer:

Option D.

Explanation:

  • The specific heat capacity of water is high, it helps in regulating body temperature.
  • The heat of vaporization of water is high the reason that the body cools down after sweating is due to this fact.
  • Water contributes to nearly 70% of the human body weight excluding bones.
  • During condensation reaction, monomer combines with other monomer from hydroxl group and water molecule is released and further reaction proceeds to form polymer.
  • Water itself is a polar molecule due to the presence of electro-negative oxygen atom it attracts positively charged hydrogen atom and can attract other polar molecules.
