What requires more energy the latent heat vaporisation of water or the latent fusion of ice?
The latent heat of vaporisation of water requires more energy. This is because on melting, the intermolecular bonds in water are only weakened whereas on boiling, the bonds are completely broken, which requires a larger amount of energy.
Why is ethanol miscible in water?
Water molecules have hydrogen bonds between them. Since they cannot form hydrogen bonds with the ethoxyethane molecules, the ethoxyethane molcules are not soluble in water.
Why oil is not dissolve in water?
oil is non-polar, so cannot form bonds with the water molecules - water molecules are polar, and hydrogen-bond to each other so for a substance to dissolve in water is must also be polar in order to form hydrogen bonds or permanent dipole - permanent dipole bonds.
What type of bonds form within a water molecule?
Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.
Can carbon form quadruple bonds?
carbons cannot have quadruple bonds.
Why does cooking a food change its hardness?
Heat can make and break chemical bonds. If something gets softer when heated (e.g. ice to water) the bonds are weakened or broken. If when heated it gets harder (e.g sauce that thickens) then the bonds are strengthened or created

Why is ethanol miscible in water?
Water molecules have hydrogen bonds between them. Since they cannot form hydrogen bonds with the ethoxyethane molecules, the ethoxyethane molcules are not soluble in water.
Why ethanol cannot react with bromine water?
The unsaturated compounds having double or triple bonds under go the addition reactions with Bromine water, ethanol does not have the double or triple bonds
What bond(s) is (are) disrupted in the presence of water?
Ionic bonds can be greatly weakened in solution. This is why, for example, table salt dissolves in water. Because of the strong attraction between the ions and water molecules, the attraction between the ions themselves is decreased.
Why oil is not dissolve in water?
oil is non-polar, so cannot form bonds with the water molecules - water molecules are polar, and hydrogen-bond to each other so for a substance to dissolve in water is must also be polar in order to form hydrogen bonds or permanent dipole - permanent dipole bonds.
What does an ice cube go through when it is melting?
The bonds between water molecules are weakened.
Ice melts why?
Ice is melted at any temperature over 0 oC; the intermolecular bonds are weakened.
What is water-water bonds called in a beaker of water?
The bonds beween the water molecules, H2O, are called hydrogen bonds.
What type of bonds form within a water molecule?
Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.
What melts an ice cube?
Ice is melted at any temperature over 0 oC; the intermolecular bonds are weakened.
How a ice cube melts?
Ice is melted at any temperature over 0 oC; the intermolecular bonds are weakened.
