Exothermic state changes release heat energy to the surroundings, such as freezing and condensation. Endothermic state changes absorb heat energy from the surroundings, like melting and vaporization.

When the temperature changes cause of a reaction is it exothermic or endothermic?

If the temperature increases during a reaction, it is exothermic. This means that heat is being released into the surroundings. If the temperature decreases during a reaction, it is endothermic, meaning heat is being absorbed from the surroundings.

What is the opposite of endothermic?

The opposite of endothermic is exothermic. Exothermic reactions release energy in the form of heat to the surroundings, while endothermic reactions absorb energy from the surroundings.

What is the difference between endothermic and exothermic change?

Endothermic reactions absorb heat from the reactants, i.e , the vessel or beaker in which the reactions have happened will be cool to touch........ Whereas in exothermic reactions, Heat will be given out and the vessel will be hot to touch..........

Is the process of condensing exothermic or endothermic?

The process of condensing is exothermic. This means that heat is released during condensation as the gas changes into a liquid state.

Is dissociation an endothermic or exothermic process?

Dissociation is an endothermic process.

What contrast endothermic and exothermic changes?

Exothermic: release of heat Endothermic: absorption of heat

How can you tell the difference between an endothermic and exothermic reaction?

You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.

Is freeezing endothermic or exothermic?

Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.

Is the formation of ammonium nitrate crystals from an aqueous state endothermic or exothermic?

Endothermic. That is why it is used in ice packs.

What is the opposite of exothermic?

The opposite of exothermic is endothermic. Exothermic reactions are those which give off energy in the form of heat. Endothermic reactions require energy.

When the temperature changes cause of a reaction is it exothermic or endothermic?

If the temperature increases during a reaction, it is exothermic. This means that heat is being released into the surroundings. If the temperature decreases during a reaction, it is endothermic, meaning heat is being absorbed from the surroundings.

How exothermic and endothermic relate to responding to external changes?

Exothermic and endothermic both have to adapt to the climate changes. For example exothermic need to move in the sun or light source when they are cold and move to a cool place when they are hot. Endothermic have to let their body temperature warm up by being in the warmest place possible, when they are cold they instantly start trying to warm up automatically.

Is burning gasoline an exothermic process or an endothermic process?

Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
