An endothermic reaction causes the surroundings to?
An endothermic reaction is one that absorbs heat energy from the surrounding environment. Therefore, an ongoing endothermic reaction will cause its surroundings to become colder. In contrast, an exothermic reaction radiates heat energy into its surroundings, which will cause the ambient environment to get warmer.
Is the reaction between copper sulphate and hydrochloric acid endothermic?
If the test tube containing the reactants mixture became hotter then it is exothermic, and if it became colder then it is endothermic. You must do the reaction to know which is which!
Is endothermic energy occurring when crystals dissolve in water and the container gets hot?
No.I know that in endothermic reactions things absorb heat or get colder. In exothermic reactions they release heat or get warmer. So, since the container gets hot I guess the energy is exothermic.
Is ice cream a exothermic or endothermic reaction?
endothermic reaction. ice - cream melts because it absorbs heat from the surrounding thus increasing its temperature. exothermic reaction is when a substance reacts with something, thus releasing heat.
Is burning of wood a endothermic change?
nope. Endothermic reactions involve the reactants including heat, but ending up with colder products. But you started with wood without heat, and ended up with a hot fire. This is an exothermic reaction.
Is ice endothermic or exothermic?
Definitions Exothermic - accompanied by, or requiring, the release of heat. Endothermic - accompanied by, or requiring, the absorption of heat. Now, does the melting ice get warmer or colder? If it gets colder, then it is exothermic. If it gets warmer, then it is endothermic. Consider how we make ice - we put water into a cold place so that it gets colder with time.

What is one similarity between exothermic reaction and an endothermic reaction?
Endothermic reactions and exothermic reactions all involve something called an enthalpy change: a change in the amount of energy a chemical contains. The difference here is that exothermic reactions release heat energy to their surroundings, whereas endothermic reactions absorb heat from their surroundings (in effect, getting colder).
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 given off in all energy changes?
energy is released which makes it hotter because it is an exothermic reaction, or energy is absorbed which makes it colder and an endothermic reaction =]

How melting is endothermic?
The process of melting is endothermic because you are adding heat (or energy) to the object. When you add heat or energy to an object it begins to melt , Which tells you the object has reached its melting point or the temperature that the object melts at.endothermic is adding heat or energy (ENdothermic means ENtering)exothermic is removing heat or energy (EXothermic means EXiting).Conversely, the process of freezing is exothermic.And easy way to remember this is that when ice melts it makes things cold. This is because it is sucking in the heat.
What is heat During the endothermic reaction?
The heat spreads to the colder substance until the two are at an equillibrium (the two objects at the end will have the same temperature)
Is burning of wood a endothermic change?
nope. Endothermic reactions involve the reactants including heat, but ending up with colder products. But you started with wood without heat, and ended up with a hot fire. This is an exothermic reaction.
Does endothermic or exothermic get colder?
Yeah, endothermic means that the heat is basically sucked out of it... or released while in an exothermic reaction, the heat is gathered or taken in. Take for example hot gas in a glass container: if it is cooled down of placed into a tub of ice, the gas will condense and the gas forms into droplets of liquid on the sides of the container and then drops to the bottom once there's enough of it.
