Answer:
The motion of the water molecules increase as heat is added.
Explanation:
Hello!
In this case, in general terms, one can know that molecules and heat have a relationship by which one affects the other, more specifically, the heat affects how the molecules behave. In such a way, as the heat added to a system increases its internal energy, one can notice that energy speeds up the molecules because they acquire such energy and the motion starts being increased, it means, the molecules start moving or vibrating faster than before of that heat addition. This is due to the increase of the internal energy, which based on the first law of thermodynamics is related with the velocity of the molecules.
Best regards!
Combustion of Fossil Fuels
Explanation:
The combustion of fossil fuels is a major contributor to unbalancing of the carbon cycle which causes more carbon dioxide to be released into the air than can be naturally processed.
Combustion of fossil fuel is an anthropogenic source of carbon dioxide emission. This chemical process is used to power internal combustion engines and industrial activities. The by product is usually carbon dioxide.
Plants that use carbon dioxide for their life processes cannot completely absorb all of this anthropogenic emission.
Naturally, animal respiration and decomposition provides enough carbon dioxide for use during photosynthesis. Combustion of fossil fuels tips this balance.

Answer:
endothermic reaction
Explanation:
It simply means that you are witnessing<u> an endothermic reaction</u>.
An endothermic reaction is one that absorbs heat energy from its surrounding, thereby leaving the reaction vessel with a lower temperature as compared to before the reaction.
It is as opposed to exothermic reactions which are reactions that give off energy in the form of heat to the surrounding, thereby leaving a reaction vessel warmer than before the reaction.
<em>In this case, the formation of ice crystals outside the test tube means that heat energy has been absorbed by the reaction which leaves the vessel a temperature cold enough to activate the formation of ice. </em>
Answer:
The word "Halloween" comes from All Hallows' Eve and means "hallowed evening."
Halloween's origins can be traced back to the ancient Celtic festival known as Samhain, which was held on November 1 in contemporary calendars. It was believed that on that day, the souls of the dead returned to their homes, so people dressed in costumes and lit bonfires to ward off spirits.
