Why does it take a lot of energy to change the temperature of water to make it vaporize?
Liquid water has an unusually high specific heatcapacity. It is one of the highest of any substance known. But, that's just another way of saying that it is hard to change water's temperature--it doesn't explain why water has a high heat capacity.Thermal energy is stored in liquid water as kinetic energy (molecular motion and rotation), as kinetic and potential energy in the vibrations of the inter-atomic bonds and, in particular, as kinetic and potential energy in the vibrations of the hydrogen bonds between molecules (H2O is a polar molecule with very strong hydrogen bonds). Much of the thermal energy that goes into water is stored as potential energyand, since temperature is a measure of only the average kinetic energy of the molecules, doesn't contribute to raising its temperature.
How much energy to boil a hard boil egg?
Entropy is a thermodynamic term. Re the hard boiling of an egg: You are going to a more "ordered" state , i.e., positive entropy. However, entropy in this case is overwhelmed by the -∆H which is the negative heat provided by the proteins hydrogen bonding. Thus, the energy driving force is the important term and not the entropy in this case.
Why does water boil at a higher temperature than butane?
the Molecular Structure of Water (H₂O) is a polar molecule with a bent shape, consisting of two hydrogen atoms and one oxygen atom. Butane (C₄H₁₀), on the other hand, is a nonpolar molecule composed of four carbon atoms bonded to ten hydrogen atoms. The polar nature of water molecules allows them to form stronger intermolecular forces compared to the nonpolar butane molecules. Intermolecular Forces: Water molecules are held together by hydrogen bonds, which are relatively strong electrostatic attractions between the positively charged hydrogen atom of one water molecule and the negatively charged oxygen atom of another water molecule. These hydrogen bonds require more energy to break, resulting in a higher boiling point for water. Butane molecules are held together by weaker van der Waals forces, which are temporary dipole-dipole interactions between nonpolar molecules. As a result, butane boils at a lower temperature compared to water.
If a substance is water soluble its solution conducts and it is hard-what kind of bonding is it?
The substance likely forms ionic bonds because ionic compounds are typically water-soluble, conductive in solution, and can form hard structures. These bonds form between a metal and a non-metal, resulting in the transfer of electrons from one atom to another.
What water boils faster salt water or sugar water?
The question is a matter of boiling point elevation. Boiling point elevation is a colligative property of water, meaning it depends on only the amount of substance dissolved in the water, not the type of substance. Thus, because table salt dissociates into its constitutive ions (Na+ and Cl-) whereas sugar does not, the same amount of table salt will increase the bp of water to a higher value. Because the b.p. of salt water would then be higher than the bp OS sugar water, it will take longer for the salt water to boil. Source : Me (maaaaad educated)
Why is it so difficult for h2o to melt and boil?
Water molecules are held together by strong hydrogen bonds due to their polar nature. In order to melt or boil water, these hydrogen bonds need to be broken, which requires a significant amount of energy. This is why water has a high melting and boiling point compared to other similar-sized molecules.
How does a soft egg become hard?
you boil it in boiling water
Why is surface tension hard?
Surface tension of water creates a lot of resistance due to hydrogen bonding. Typically, hydrogen bonds are fairly weak. However, they like to bond on all sides. Thus, at the surface of the water, the bonds on top have nothing to bond to, so they stretch to the sides, strengthening the side-to-side bonds between water molecules on the surface.
What is the best way to hard boil eggs?
boiled water
Which of these substances contain molecules that will not form hydrogen bonds hydrogen hydrogen Fluoride Water or Ammonia?
Its hard to answer your question since you did not use commas. But... if the question is hydrogen, hydrogen fluoride, water or Ammonia then.. Hydrogen...is diatomic naturally so I'm not sure which you are referring too. It can not hydrogen bond with its self but it could act as a hydrogen donor and something like an ether could act as the proton acceptor. Then they could both participate in hydrogen bonding. Same answer as above goes from Ammonia. HF, can hydrogen bond with it's self and other molecules containing fluorine, Nitrogen or Oxygen. Same answer as above goes for water.
How do you turn hard water soft?
You can use a water filter(Brita is best!!) Or you can boil or distill it.
Why do we need to hard boil and egg?
An egg, a heat source, a container, water
How are hydrogen bonds different from covalent bonds?
Hydrogen bonds are weaker intermolecular forces that occur between molecules with hydrogen atoms bound to highly electronegative atoms like oxygen or nitrogen, whereas covalent bonds are strong intramolecular forces formed by sharing electrons between atoms. Covalent bonds involve a sharing of electrons between atoms, while hydrogen bonds involve an attraction between partial positive and negative charges on different molecules.
How can I effectively boil hard water to make it safe for consumption and other household uses?
To effectively boil hard water for safe consumption and household use, bring the water to a rolling boil for at least one minute. This will kill harmful bacteria and parasites that may be present. Allow the water to cool before using it. Boiling does not remove minerals that cause water hardness, but it does make the water safe to drink and use for other purposes.
What type of bond is very hard and brittle?
ionic bonds
How do you boil fresh eggs?
Put enough water in a pan to completely submerge the egg. Add a little salt or vinegar. Bring the water to the boil. Add the egg. Boil for 3 - 5 minutes depending on personal preference. Soft or hard boiled.
Are hydrogen bonds strong?
The term hydrogen bonding refers to a weak interaction between two molecules that contain an H atom bonded to a very electronegative atom, such O, N, and F. Hydrogen bonding does not occur within molecules, but rather between to molecules.Of course, the atoms of hydrogen can also form regular covalent or ionic bonds with other atoms to form molecules, and so these are in some sense hydrogen bonds, but that's not usually what people mean when they say the term "hydrogen bond."See the Web Links for more information about hydrogen bonding.
