Explanation: Entropy is the measure of randomness or disorder of a system. More is the random arrangement of molecules in a system , more is the entropy of the system. More ordered is the arrangement of molecules in a system, less is the entropy of the system.
When carbon dioxide sublimes, it means solid carbon dioxide is directly changing to gaseous state without undergoing into liquid state, thus the molecules will be more random and thus the entropy will increase.
Answer is: It expands when it freezes.
When molecule frezes, it lose energy. When molecules are far apart, it means the volume is greater and it expands.
For example, ice expands when water is freezing.
Hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (H), covalently bound to a highly electronegative atom such as flourine (F), oxygen (O) and nitrogen (N) atoms.

A computed tomography (CT) scan fires radiation through the body to create an image. A CT scan uses x-rays radiation which are form of an ionizing radiation.
The radiation which have enough energy to cause ionization by passing through that medium is called ionizing radiation. The ionizing radiation are x-rays and gamma rays.

Answer: B. lipids
Explanation:
When an individual has an energy surplus, the extra energy is stored in the body as lipids. Lipids are used for energy in the long term
