Q: Answer the following question given this paragraph: There are many examples in the chemical world of changes in entropy. Phase transitions are one obvious example. When a substance makes a transition from the liquid state to the gaseous state, the particles have many more possible arrangements, because they are no longer confined to a specified volume in which they are close to each other; gas particles can move freely throughout their container. Vaporization represents an increase in entropy. In the opposite direction, a liquid loses entropy when it freezes to a solid. Because solids have very ordered structures, there are fewer possible arrangements of particles that would result in the properties associated with a solid. Q: The phase transition of a substance changing from a liquid state to a gaseous state is an example of what? A:

OPTIONS:
- trichina
- spirogyra
- catostrophy
- entropoy

A: entropoy

input: OPTIONS:
- isotopic decay
- radioactive decrease
- secondary decay
- radioactive decay Now, answer this question: Answer the following question given this paragraph: Radioactive decay is the breakdown of unstable isotopes into stable elements. For example, carbon-14 is an unstable isotope of carbon that decays to the stable element nitrogen-14. The rate of decay of an isotope is measured in half-lives. A half-life is the time it takes for half a given amount of an isotope to decay. Q: What is the term for the breakdown of unstable isotopes into stable elements? A:
A:
output: radioactive decay

Answer the following question given this paragraph: A base is an ionic compound that produces negative hydroxide ions when dissolved in water. Bases taste bitter and turn red litmus paper blue. Q: What is an ionic compound that produces negative hydroxide ions when dissolved in water A:

OPTIONS:
- catalyst
- acid
- isomer
- base

Answer: base

Problem: OPTIONS:
- small intestine
- stomach
- spleen
- gall bladder
Q: Answer the following question given this paragraph: A related mechanism allows us to absorb and digest the fats in buttered popcorn and French fries. To solubilize the fats so that they can be absorbed, the gall bladder secretes a fluid called bile into the small intestine. Bile contains a variety of bile salts, detergent-like molecules that emulsify the fats. Q: To solubilize the fats so that they can be absorbed, what organ secretes a fluid called bile into the small intestine? A:
Answer: gall bladder

Answer the following question given this paragraph: An alloy is a mixture of a metal with one or more other elements. The other elements may be metals, nonmetals, or both. An alloy is formed by melting a metal and dissolving the other elements in it. The molten solution is then allowed to cool and harden. Alloys generally have more useful properties than pure metals. Several examples of alloys are described and pictured below. You can learn about another alloythe amazing alloy called memory wireat the following URL. If you have braces on your teeth, you might even have this alloy in your mouth!. Q: What is a mixture of metal with one or more other elements? A:

OPTIONS:
- an alkali metal
- a halloid
- a metalloid
- an alloy

Answer:
an alloy
