Do all please thank you. If not some is ok.
shusha [124]

Answer:

1. Increases

2. Decreases

3. Increases

4. Decreases

5. Increases

6. Increases

Explanation:

Raising air temperature increases temperature of our body while on the other hand, if the air temperature decreases the temperature of our body also decreases because high air temperature heats up our skin surface and low air temperature cools down our skin surface which ultimately increases or decreases the internal body temperature. Adding clothing increases body temperature due to capturing of heat produced by our body. Sweating cools down our body temperature because the water takes the internal heat with itself to the outside. In shivering, the body produced heat so the body temperature increases. Exercising also produces heat inside our body which increases the body temperature.

List 3 factors that can speed up the rate of chemical reactions
zysi [14]

Answer:

  1. Temperature
  2. Greater Surface Area
  3. Catalysts

Explanation:

Temperature

  • An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).

Greater Surface Area

  • The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. ... more particles are exposed to the other reactant. there are more collisions. the rate of reaction increases.

Catalysts

  • A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.

Hope this help!!!
