Is Ice Melting Endodermal or Ecodothermic?

Hi

endothermic => absorbs heat

exothermic = heat emitted

Melted ice = absorbs heat from the atmosphere or when placed in the oven, etc. So it's endothermic.

But exothermic or endothermic terms are commonly used for reaction, and melting ice is not a reaction, it is just a phase change that absorbs heat.

If I were with you, I wouldn't say that, but if your teacher asks that question, there could be a conclusive answer.

For example, I help.

Is Cast Iron Endodermic or Ecuador?

Is Cast Iron Exodormic?

For the best answer this, find on this site 0 Adding salt to water is endothermic, Delta S> H2 gas combustion is exothermic, Delta S0. These ideas are often well-crafted and the questions are often bad. In the case of molten water, the whole system is compatible with its surroundings at some point, when this happens, Delta S = 0 (no additional change) and l have the same S value of the environment / system. Using the term delta amp, some kind of entropy shift occurs. S and Solid> Liquid, S Liquid Increases> Gas, S Increases N in Molecules, S 2H2 + O2> 2H20 Increases the Combustion of a Gas for Two Combustions of Three Gases S and see the end of the process. . It can be argued that combustion causes the gas to expand and become more active, which in turn produces more randomness in the water vapor, resulting in larger deltas. ۔ However, 2 gases are less random than 3 gases, so it can also be said that Delta S is smaller. To find out if Delta S is increasing or decreasing, you really need to do some math. The same goes for adding salt (NaCl) to water. This process leads to a higher delta S. However, the addition of iron or aluminum salts in the water causes less delta S due to less hydration. The ion itself forces a higher order on the liquid, you can imagine it as a liquid crystal. And finally, part of that consistency comes from a mix of ideas. Entropy is a physical condition, just like its physical condition or growth. Heat (endo / echo) is not a physical state, but a state. There is not much to say about the expo / endo reaction. S, with enthalpy transformation and free energy, can also be used to predict whether rxn is non-synthetic and whether it will be ono or exo. In general, a strict rule of thumb applies here: when a system absorbs heat (endo) from its surroundings, the delta s (sis) increases, the delta s (above) decreases. When a system releases heat (expo) to the atmosphere, the delta s (cs) decreases, the delta s (more) increases. This sounds like a no-brainer, but as I said, these things are usually written in simple words. It may be typo or it means the environment is restricted. In other words, when the atmosphere is heated, the system absorbs heat, which makes the system more random. Or they take a very limited stand and talk about solid or liquid combustion, where you have an exile that has Delta S I don't have Delta H for ice, but liquids And water vapor. The result is the same H2O (l) = delta H 285.8 H2O (g) = delta H 241.8 change from liquid to gas, ie, liquid gas 241.8 (285.8) = 44 T (delta H) = delta ST (44) = delta s delta S should be positive because T and Delta H are positive. Rxn is clearly endothermic if exothermic and does not cool down when sweating.

Ice requires energy to break the bonds between water molecules. This is called the heat of Zion.

Ice and water stay at 0 سین C until all the ice melts.

In nature, hot air or sunlight purifies energy.

Is Melting Endothermic Or Exothermic

Is Melting Endothermic Or Exothermic

It is endothermic because energy only melts when energy is obtained.

Endodermic because ice absorbs energy when it melts.

Every physical change in the direction of solid> liquid> gas requires the absorption of energy to control the gravitational pull of the particles as they move from solid to liquid or liquid or gas to solid. .

Because melting ice changes from solid to liquid in the form of water, it requires energy, which makes it an endothermic process.

Alternatively, the reverse process will release energy and become exothermic.

Ice melting is an exothermic process: wrong
