Bob has a cup of hot chili. It is too hot to eat.

After ten minutes, the chili is cool enough for him to eat.
What has happened to the chili's thermal energy?

A.
It has increased the air's potential energy.
B.
It has increased the chili's kinetic energy.
C.
It has increased the air's thermal energy.
D.
It has increased the chili's potential energy.

The answer is It has increased the air's thermal energy. Which is C.

Explanation:

Over time, thermal energy tends to spread out through a material and from one material to another. As a result, a hot material tends to cool down over time.

Since the chili is in contact with the air, some of its thermal energy transferred to the surrounding air, thereby increasing the air's thermal energy.

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
