Answer:
Which of the following is LEAST characteristic of a complex organism?
Symbiotic relationship
Explanation:
The best material to use is foam, since it is the best insulator. An insulator will help slow the
transfer of heat from outside of the lunchbox to inside of the lunchbox. The extra layer will be of foam.
Explanation:
If we compare the specific heat capacity of rubber and foam it can be found that foam has high specific heat capacity, which indicates that it is the good insulator.
An insulator is a substance in which heat exchange between medium and surrounding is very low.
Jayla and her grandma wanted their food to be cold all morning so foam as an insulator is the best choice.
Thus, high specific heat energy means large amount of energy required to raise the temperature by 1 degree in response to the mass of the substance as per unit mass.
Answer:
The crust, mantle and inner core are defined by chemical composition
