endothermic process

The ice melts in an endothermic process while dissolving the acid.

As I remember endothermic processes are only possible if they result in an increase in entropy within the reaction.

Evaporation of the sweat produces cooling, since this endothermic process draws heat from the body.

His endothermic process required a maximum cooling rate of 1.2 GW.

It is used in instant cold packs, as hydrating the salt is an endothermic process.

Similarly, in an endothermic process, the energy absorbed by the system is equal to the energy lost by the surroundings.

Evaporation is an endothermic process, in that heat is absorbed during evaporation.

The opposite of an exothermic process is an endothermic process, one that absorbs energy in the form of heat.

The decomposition of the concrete and volatilization of its alkali components is an endothermic process.

Fusion can not proceed any further except through an endothermic process, and so further energy can only be produced through gravitational collapse.

Kinetic energy added (endothermic process) to gas particles by way of collisions produces linear, rotational, and vibrational motion.

Hailstones melt and raindrops evaporate-this is an endothermic process that demands a lot of energy (in the form of latent heat) so the air is cooled.

The dehydroxylation of kaolin to metakaolin is an endothermic process due to the large amount of energy required to remove the chemically bonded hydroxyl ions.

That means fusion processes producing nuclei that have atomic numbers higher than about 26, and atomic masses higher than about 60, is an endothermic process.

Ammonium bicarbonate decomposes above about 36 C into ammonia, carbon dioxide, and water in an endothermic process and so causes a drop in the temperature of the water:

All endothermic processes are driven towards making more products when you add heat; thus, when you heat the system, the process tends more towards products and the salt becomes easier to dissolve.

Cooling Each time the gun is fired there is rapid evaporation of liquid to gas, which is an endothermic process in which the pressure drops until enough ambient heat is absorbed to restore the pressure.

I assume that what you called 25% yield means that your experimental result was 25% too low compared to the literature value, so the error is in the right direction for some endothermic process - let's assume the melting of polystyrene.

Lithium sulfate is soluble in water, though it does not follow the usual trend of solubility versus temperature - its solubility in water decreases with increasing temperature, as its dissolution is an endothermic process.

Although there are many exceptions that could be found, the origin of this trend is that a gas-producing chemical reaction has an endothermic process imbedded in the reaction - the latent heat of vaporization of a liquid (or solid) product.

Some older textbooks define lattice energy as the energy required to convert the ionic compound into gaseous ions which is an endothermic process, and following this definition the lattice energy of NaCl would be +787 kJ/mol.

The structure, bonding and acidity of Sn-beta zeolite has been studied using periodic DFT and it has been demonstrated that incorporation of Sn in BEA framework reduces the cohesive energy and is an endothermic process.
