Answer:
B. The foam has tiny air pockets that slow the transfer of thermal
energy away from the water in the pipe
Explanation:
Air is a poor conductor thermal energy and can be used as good insulator. Insulators are poor conductors of heat.
When it is freezing outside, the temperature gradient will tend to adjust to the ambient one. The water in the pipe being at a higher temperature will tend to lose heat energy to the surrounding.
The layer of foam will prevent this form of heat exchange from happening because of the air pocket that is present around.
Answer:
B. Constants
Explanation:
Constants are the factors that stay the same throughout the entire experiment no matter which group. The definition of a constant is "a situation or state of affairs that does not change." this furthers the point that constant is the correct answer because they don't change in the experiment.
Nonmetals are to the right of the line on the periodic table
Answer:
Jasmine's body responds with a mechanism of heat loss, such as sweating and evaporation, to reduce her internal body temperature and recover homeostasis.
Explanation:
The human is a homeotherm organism, with a constant body temperature that is between 36.5 and 37 °C. To maintain thermal homeostasis uses several mechanisms.
In the case of Jasmine, the raise of the body temperature, with the exercise, to 38°C stimulates sweat production and its body surface becomes moist. With the evaporation of sweat, body temperature normalizes, since this process involves heat loss.
Also, a voluntary mechanism to lower the temperature is to remove the clothes and remain in a cool environment.
