Answer the following question given this paragraph: When fuel is burned, most of the energy is released as heat. Some of this heat can be used to do work. Heat cooks food or warms your house. Sometimes the heat is just waste heat. It still heats the environment, though. Q: When fuel is burned, most of the energy is released in what form? Choices: - precipitation - carbon dioxide - humidity - heat A:
heat

Ques: Answer the following question given this paragraph: Mollusks are invertebrates such as snails, scallops, and squids. They have a hard outer shell. There is a layer of tissue called the mantle between the shell and the body. Most mollusks have tentacles for feeding and sensing, and many have a muscular foot. Mollusks also have a coelom, a complete digestive system, and specialized organs for excretion. The majority of mollusks live in the ocean. Different classes of mollusks have different ways of obtaining food. Q: Snails, scallops, and squids are what type of invertebrate? Choices: - crustacean - algae - arthropod - mollusk A:
Ans: mollusk
(Q).
Answer the following question given this paragraph: The type of atom is determined by the atomic number (i. e. the number of protons). The atomic mass of an atom is approximately the number of protons plus the number of neutrons. Typically, the atomic mass listed in a periodic table is an average, weighted by the natural abundances of different isotopes. Q: Adding the number of protons plus the number of neutrons in an atom, decides it's approximate mass, what is another word for this value? Choices: - electron count - atomic mass - real number - atomic number A:
(A).
atomic number
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
Answer the following question given this paragraph: An acid-base indicator is a substance that displays different colors when in the presence of an acid or a base. How does that work? An indicator is a weak acid that ionizes within a known pH range, usually about 2 pH units. We can represent the protonated form of the indicator molecule as HIn and the deprotonated form as In . The following equilibrium exists for the indicator. Q: A substance that displays different colors when in the presence of an acid or a base is called what? Choices: - pH scale - reactor - litmus test - an acid-base indicator A:
an acid-base indicator
