Due to "<u>Temperature</u>" difference heat is transferred from "one object" to "another object".

<u>Explanation</u>:

In general there are three ways for heat to be transferred: Conduction (heat is transferred by vibration of particles), Convection (heat is transferred by movement of particles) & Radiation (heat is transferred in Infrared waves). Heat is also called as thermal energy which acts as kinetic energy when energy is given to atoms, molecules, ions in solids, liquids and gases due to which movement takes place. As heat flows from higher temperature to lower temperature and heat content “Q” of an object depend upon its specific heat “c” and its mass “m”. For example when ice cube is added to room temperature water then transfer of heat energy will take place due to which ice melts in water and both of them reach to a common temperature which is also called as “Thermal Equilibrium” phase.

Explanation:

21. Atoms are not created or destroyed means that atoms that you begin with are the atoms that you will end with. The catch is that the atoms will rearrange to give you new compounds, but the atoms that you initially had are the atoms you will still have after reaction. For eg, if you started with eggs and made omelet. Omelet is a "new" compound, but the atoms that were in the eggs have rearranged to become the omelet so can you see that atoms were not created or destroyed to make the omelet.

22. Yes because amount of products you make depends on how much reactants you have. For eg, I need two graham cracker(GC), one marshmallow(M), and one chocolate (C) to make a s'more. If I get more of each item then I can make more s'mores and consequently having minimum amounts results in less s'mores that I make.

23. Not possible, due to law of conservation of matter and energy. Atoms cannot be created nor be destroyed, they are simply rearranged. For eg, Taking A + B cannot give you a new compound with a chemical formula D or XZ. A + B can however give you AB which is rearrangement of the starting atoms.

24. Chemical equation is balanced when atoms on reactant side and atoms of product side are in equal counts. I have attached a graphic below for more help.
