They could be used for making science test or other things, per example: Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.
What else can I help you with?
If the reaction gets hot is it an endothermic or an exothermic reaction?
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
Does endothermic absorb or release energy?
Both, actually. Heat is released by the system (the object or area you're studying), and is absorbed by the surroundings (everything else, not including the system). Typically people are referring to the effects on the system, so in that case an exothermic reaction is a release of heat.
When oil is burned is it endothermic?
Fire creates an exothermic reaction, not endothermic. To be endothermic, the reaction must draw in heat from its surroundings, thereby making things colder.
What is exothenmic?
Something that is exothermic is something that puts off or "exits" energy, usually in the form of heat. This term can be used in relation to chemical equations, light, and anything else involving energy. The heat produced from boiling water is exothermic. The combustion of fuels, the corrosion of metals, and the use of a battery are also examples of exothermic reactions.
Are timber wolves endothermic?
Yes, wolves, along with anything else that has hair, are endothermic. Endothermic means 'warm-blooded,' which is all animals except for the reptiles, and I'm pretty unfamiliar with all the sea critters. Warm-blooded, or endothermic, means that you control and maintain your own body temperature. Cold-blooded, or exothermic, means that your body doesn't control its temperature and can't maintain it; it relies on its surroundings to maintain its temperature so it has to be lenient about how high and low it will let the body get before dying.
What is chemical reaction that gives off heat called?
Exothermic reactions give off heat.
The heat energy content of the reactants of an endothermic reaction compared with products is?
In an exothermic reaction the reactants release energy to the environment when they react - like coal burning. In an endothermic reaction the reactants need to absorb energy from their environment when they react, so the reaction feels cold in your hand, or else you have to heat it continually to make it react. The products would then be at a higher energy level than the reactant were. Photosynthesis is an interesting example of an endothermic reaction, because in this example the energy supplied to make the reaction go is not heat but light. The product (sugar) is an 'energy store' which the plant (or whatever eats the plant) can use later on to release the energy in respiration.
What else keeps the sun's gases in motion?
Chemical reactions
Could he have someone else?
Yes, a man could have someone else.
What else could it be?
she could do other things
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
How else might the energy released be used in mammals and in birds?
For keeping there body at optimum temperature for caring out enzyme reactions
