The answer is letter B, because according to the Second Law of Thermodynamics heat can only move from a hotter body to one of colder temperature. So that's your answer: as the molecules in the pie move faster (are hotter) than the ones in the skin, heat is transfered from the pie to the skin.
Answer:
esters
Explanation:
The -OR group of the alcohol replaces the -OH of the carboxylic acid, forming an ester. See attachment for condensed mechanism.
Hello!
Graphs are used to understand an object's motion because they can show the exact location of the object at any given moment.
This is done with the help of a reference system. The most common reference system is the Cartesian coordinate system, which describes the location of an object through a set of 2 or 3 coordinates (depending if the system is in 2D or 3D).
Studying graphs of movement, we can know if the movement is cyclical, or the direction of the movement, determine tendencies and overall getting an unambiguous and precise understanding of the motion.
Have a good day!
