In chemistry, a chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Both reactants and products are involved in the chemical reactions.

In chemistry, energy is what is required to bring about a chemical reaction. The total energy of a system is the sum of the potential energy of its constituent particles and the kinetic energy of these particles. Chemical energy, also called bond energy, is the potential energy stored in the chemical bonds of a substance. Chemical energy is released when a bond is broken during chemical reactions.

okay, in this question, we're going to be discussing why we have such huge temperature extremes for day and night in desert regions, and we have much more temperate or non variable climates by coasts. And there's a couple reasons for this. So actually there's several reasons. But let's talk first about humidity. Coastal areas have high humidity, and humidity is water vapor. They have a higher water vapor, and water vapor has a relatively high specific heat, so that high specific mean heat means that hangs onto or its ableto have a lot of heat. When it's cold out, it will release some of the heat into the atmosphere, and when it's hot, it will absorb some of the heat. So it's moderating, and obviously deserts lack that desserts have low humidity, so they have low water vapor. An air has a much lower specific heat, so it doesn't have the moderating abilities. So also, um, when we look at what the coastal region, a coastal region, has water, which is like the highest specific heat of anything has tons of water, and that water is probably the most moderating thing in the world. Maybe the universe. Who knows the H 20 has a super super. I'm going to give it a double up arrow high specific heat, so it's very moderating. It will absorb baton during a ton of energy during the day, and it will give off a ton of energy during the night to keep the temperature moderate in the desert. By comparison, it doesn't have water. It's got like sand and rocks, both of which have very low, ultra low specific heats. And that means they just, like, get they observed their heat and give it off so quickly. So it has a very poor temperature moderating temp, moderating properties. That's it in a nutshell.
