Not normally. It's usually endothermic (Takes heat in) as it needs energy to make the bonds between atoms/molecules.

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.
Is hydrogen gas explosion endothermic or exothermic and why?
Exothermic
Why is work positive in an exothermic reaction?
kind of depends on the reaction. ex. solid and a liquid react causing a an aqueous solution and a gas to form. when a gas is formed the gas expands causing it to do work on its surroundings causing work to be negative.
Is drain cleaner endothermic or exothermic?
Drain cleaner is typically exothermic. When it is mixed with water, it produces heat as a result of an exothermic chemical reaction. This heat helps to dissolve and remove the clogs in the drain.
Is a pencil a solid liquid or gas?
A pencil is a solid object.

What are 3 phase changes of exothermic?
freezing (liquid to solid), condensing (gas to liquid), and deposition (gas to solid)
What three phase changes ar exothermic?
Gas to liquid (condensation)Liquid to solid (freezing)Gas to solid (desposition)
Is solid exothermic or endothermic?
A solid is itself neither endothermic or exothermic. However the phase change from liquid to solid will likely be exothermic.
Which phase change is an exothermic process?
Change of phase from gas to liquid to solid are exothermic reaction. Condensation, deposition and freezing are exothermic processes that undergo change in phase.
Why is the diffusion of a gas in a vacuum exothermic?
It is exothermic because the gas is expanding. Most processes that have to do with expansion are exothermic/
Is hydrogen gas explosion endothermic or exothermic and why?
Exothermic
Which phase changes are endothermic?
Based on chemical properties exothermic phase changes are those that release energy. The exothermic phase changes are gas--> liquid, liquid --> solid, and gas--> solid. Looking at a phase diagram if you are going up the "stairs" the conversions require energy going down the "stairs" energy is released.
When Natural gas is burned in a furnace is it endothermic or exothermic?
exothermic
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.
If and Egg cooks in boiling water and turns the yolk to a solid is it an endothermc or exothermic?
exothermic
Is liquid to a gas endothermic or exothermic?
It is exothermic. The gas must release energy to its surrounding to become a liquid.
