Q: Answer the following question given this paragraph: Maintaining a high metabolic rate takes a lot of energy. The energy must come from food. Therefore, mammals need a nutritious and plentiful diet. The diets of mammals are diverse. Except for leaf litter and wood, almost any kind of organic matter may be eaten by mammals. Q: Maintaining a high metabolic rate takes a lot of what? A:
Answer: energy

Problem:OPTIONS:
- physical insulator
- structure insulator
- thermal condenser
- thermal insulator

Answer the following question given this paragraph: Another example of a thermal insulator is pictured in the Figure below . The picture shows fluffy pink insulation inside the attic of a home. Like the down filling in a snowsuit, the insulation traps a lot of air. The insulation helps to prevent the transfer of thermal energy into the house on hot days and out of the house on cold days. Other materials that are thermal insulators include plastic and wood. That's why pot handles and cooking utensils are often made of these materials. Notice that the outside of the toaster pictured in the opening image is made of plastic. The plastic casing helps prevent the transfer of thermal energy from the heating element inside to the outer surface of the toaster where it could cause burns.

Q: What is the name for a material that prevents the transfer of heat energy? A:
****
A: thermal insulator

- chemical reaction Now, answer this question: Answer the following question given this paragraph: Not all changes in matter involve chemical reactions. For example, there are no chemical reactions involved in changes of state. When liquid water freezes or evaporates, it is still water. No bonds are broken and no new products are formed. Q: Changes of state of matter do not involve what type of reaction? A:
A:
output:
chemical reaction
