What happens to energy when a substance is melted or boiled Is this endothermic or exothermic?
When a substance is melted or boiled, energy is absorbed from the surroundings, which is characteristic of an endothermic process. In melting, the energy breaks the bonds between particles, allowing them to move more freely as a liquid. Similarly, during boiling, energy further breaks the intermolecular forces, transforming the liquid into a gas. Thus, both melting and boiling require energy input, making them endothermic reactions.

Is digesting food exothermic?
It is true to say that it could be either, but most would agree that cooking food is endothermic - food takes in the heat during cooking, and doesn't release it while cooking. The heat is circulated through the food when it is cooking, making it endothermic. Some foods release the heat, but this is only after the food has been cut.Cooking an egg is an endothermic process. The egg absorbs the heat from the water and does not release it. Perhaps if you are making hard boiled eggs you could say that it is both - endothermic while cooking and exothermic while cooking. Though the cooking process is absolutely endothermic.
What is an example of a physical change that makes the substance disappear?
Evaporation, as when water is boiled. It changes phase, from a liquid to water vapor, a gas which is invisible.
What happens when carbon is boiled in concentrated H2SO4?
The reaction is:C + 2 H2SO4 = CO2 + 2 SO2 + 2 H2O
Can you pasteurize water?
No, water cannot be pasteurized as it is an inorganic substance without living organisms. However, water can be boiled to kill pathogens and make it safe for consumption.
What happens when carrot is boiled and then placed in concentrated salt solution?
the cells are dead so the potato whould not perform any movement

What happens when liquids boiled?
when liquid is boiled it convert into steam and become vapour
What happens to a boiled egg albumin?
It coagulates.
What happens when sap is boiled?
it runs away
What happens to a sugar solution when boiled?
It evaporates.
What happens to water when it is boiled?
It changes to a gas (steam).
What happens to water when boiled does it condensate or does it evaporate?
When water is boiled is transformed in a gas; the reverse process is called condensation.
Which phase change is endothermic?
The 3 types of endothermic phase changes are the movement from solid to liquid, the movement from liquid to gas, and the movement form gas to plasma. Endothermic is the absorbing of heat.
What happens to the density of water after you boiled it?
Pretty much nothing.
What happens when green leaf is boiled in water?
it will make holes
What happens after water is boiled?
You turn the stove off and start cooking
Why are cocoons boiled in hot water?
cocoons are boiled in hot water so that the gummy substance called the sericin can come out so that it is easy to pull out the thread called silk
