About how long would it take for one of the footprints left by the apollo astronauts to be erased? (hints: use the moon's surface area to determine the impact rate per square centimeter, and estimate the size of a footprint.)

time take for one of the footprints left to be erased is ( 1.21 * 10^9 ) degree

Its A, C and D

Explanation:

A= correct because when you add heat to a solid it starts to melt and turn to liquid

B= Incorrect because the more heat that's dded the faster the atoms in the object will move and that creates energy

C= Correct because the liquid is in fact changing to a gas as more heat is added.

D= Correct because as i explained in B the more heat added the more energy is there
