Answer the following question given this paragraph: Alloys that are mostly composed of mercury are known as amalgams . Amalgams often have special properties that stem from the fact that mercury exists as a liquid at room temperature. As a result, metal amalgams are used for a variety of purposes, including dentistry and the extraction of other pure metals such as gold. Q: What are alloys that are mostly composed of mercury known as? Choices: - halogens - fillings - compounds - amalgams A:
(Answer)
amalgams

Ques:Answer the following question given this paragraph: The process in which a liquid boils and changes to a gas is called vaporization . The temperature at which a liquid boils is its boiling point. The boiling point of water is 100C (212F). Other types of matter may have higher or lower boiling points. For example, the boiling point of table salt is 1413C. The boiling point of nitrogen is -196C. Q: What is the process in which a liquid boils and changes to a gas? Choices: - sublimation - freezing - melting - vaporization A:

Ans:vaporization
Ques: Answer the following question given this paragraph: Smooth muscles and cardiac muscles are not attached to bone. Recall that these types of muscles are under involuntary control. Smooth muscle is responsible for the contractility of hollow organs, such as blood vessels, the gastrointestinal tract, the bladder, or the uterus. Like skeletal muscles, smooth muscle fibers do contract together, causing the muscle to shorten. Smooth muscles have numerous functions, including the following. Q: What kind of muscle is responsible for hollow organs contracting? Choices: - micro muscle - tough muscle - rough muscle - smooth muscle A:
Ans:
smooth muscle
