Where does energy come from an endothermic reaction?
From the surroundings. From Wikipedia: "...a process or reaction in which the system absorbs energy from its surroundings in the form of (usually, but not always) heat."
What is the function of dehydrate calcium chloride?
Anhydrous calcium chloride (CaCl2) is extremely hygroscopic, meaning it readily adsorbs water or moisture from the surroundings. Therefore, calcium chloride is commonly used as a dessicant.
When Energy is absorbed from the surroundings and the temperature of the surroundings decreases' What reaction is this?
This is an endothermic reaction.
A gaseous system at equilibrium with its surroundings as molecules of A collide with molecules of B without reacting the total energy of the gaseous system decreases increases or remain same?
Remains the same
What happens to the heat in a system and in the surroundings in an exothermic reaction?
the system releases heat,meaning that energy is generatered.
Does a closed system exchange energy with the outside?
Yes it can... An open system can exchange both energy and matter with its surroundings, where as a closed system CAN exchange energy, but CANNOT exchange matter with its surroundings. Also, an isolated system cannot exchange energy nor matter with its surroundings.
What is an open system in enviromental science?
An open system is one that exchanges both matter and energy with its surroundings. For example, suppose Earth is a system and the universe is its surroundings. Earth is an open system, since it can exchange both energy and matter with its surroundings.
What is a system energy?
Any process in which a system interacts with its surroundings in such a way that the energy of the system increases (or decreases) while that of ...
What is a energy transfer system?
Any process in which a system interacts with its surroundings in such a way that the energy of the system increases (or decreases) while that of ...
What system in which both energy and matter are exchanged with the surroundings is called a?
Closed system
You say all systems try to go to their stabler state and the Entropy of Universe is increasing how do you justify both the statements?
The state of maximum entropy of a system is the state when all the energy available to a system to do work is dissipated and is evened out with that of the surroundings. Therefore, the ability to do work relates to the difference in energy levels between a system and its surroundings. A system will carry on working for as long as there is energy difference between it and its surroundings. When the energy of a system and its surroundings evens out, the system ceases to function. All functional systems try, but fail to reach that equilibrium. The Universe as a system is no different. However, the energy which causes the universe to expand -- termed dark energy, which source remains unknown, cause the Universe to do work on its surroundings. Therefore, as a system, the Universe must receive or must have received its energy from its surroundings.

What is a exothermic change?
It is when something releases its energy to its surroundings do to a system.
What is it called when energy is unable to pass from a system to the surroundings?
insulated
How is evaporation used for energy transfer?
In order to evaporate, energy has to be added to the system, so there will be energy transfer from the surroundings into the material being evaporated, with the effect of cooling the surroundings.
What is a closed systems?
A system that cannot exchange matter with its surroundings A system that allows energy to move in and out but not mass ~ Apex
What is it called when a substance releases energy to its surroundings?
There are two ways that a substance ( called the System ) may release energy to the Surroundings :( 1 ) Heat may be released by heat transfer from the System to the Surroundings. Heat transfer from the System to the Surroundings requires the System temperature to exceed the temperature of the Surroundings and the presence of one or more heat transfer modes ( conduction, convection, and/or radiation.( 2 ) Work done by the System of on the Surroundings corresponding to a force moving through a distance, such as when the substance expands. Substance confined to a cylinder with a piston may expand, doing work on the Surroundings.
