Because of the strong intermolecular bonds , i.e. hydrogen bonding and polarity (dipoles).

Why is a metal plate used in heat sinks?
because metal is a good conductor of energy (there are a lot of free electrons in a metal) and this will cause the metal to absorb and radiate more energy combined with the increased surface area of the heat sink
Which has greater heat energy water tank of electric kettle?
the tank must have a graeter amount of energy because it has to heat up more water there for it requirs more energy to do so
Why does a metal spoon take in more heat?
Because collisions between electrons and other particles in metal enable thermal energy to be transferred more quickly.
How is the properties of water glycerol and oil compaired to the properties of the liquid in radiators?
The more vigorously they oscillate, the more energy they have, the hotter the metal (more heat). If the metal is heated too much, the atoms oscillate too vigorously to stay at their fixed positions hope this helps :-)
Which heat is stored in water vapour?
The heat is stored in water vapour is latent heat.Latent heat describes energy that is not stored as the internal energy (i.e. temperature) of an object but in its phase state.For example, in the atmosphere heat that is transported by an air parcel that contains more water vapor than its surroundings. Because energy is needed to turn water into water vapor, water vapor is a way for a body to store energy (along with potential energy, kinetic energy, and sensible heat). If the water vapor is returned to a liquid or solid phase (by condensation or sublimation), the stored energy is released as sensible heat.
What is the specific heat of other common materials?
Much lower. Consider water's superior ability to retail heat and compare that with a metal's rapid heat gain. It takes more energy to increase the temperature of water than to heat the metal of pot (as you will no doubt know if you have burned yourself on hot metal).
What can take more heat metal or stone?
water
Why did you need to transfer the metal quickly from the hot water bath to water in the styrofoam cup calorimeter?
You need to stir the water because the heat energy coming off whatever you put into the calorimeter (whether it be food, metal, etc.) won't evenly distribute its heat throughout the water, and therefore the temperature reading won't be as accurate. If you stir it, the heat will be more evenly "mixed in" with the water, so to speak, and you will get a more accurate reading.
When you boil water in a pot on the stove which heats faster the metal or the water?
Some metals do heat up faster than water, depending on the metal But usually, the metal would heat up faster because it is a solid, and water takes a bit longer to absorb the heat, hence why the water in a pool is cold until around 12 am before getting to a regular tempature.

Why salt dissolves best in hot water?
Heat has more energy, so salt dissolve faster in hot water, because there is more heat and more energy.
Does metal with high heat capacity raise temperature of water more than a metal with low heat capacity?
yes

the tank must have a graeter amount of energy because it has to heat up more water there for it requirs more energy to do so
How do water and land surfaces differ in their abilities to absorb and radiated heat energy?
Land absorbs more heat energy than water does.
Does water require energy?
If you take energy in the form of heat, from water it will freeze and so is not water any more.
Describe What happens to the particles in the metal lid when it is run under hot water. why does this trick the lid to be removed more easily?
The heat causes the metal to expand making the lid slightly bigger so that it breaks contact with the jar. That's what it does, how it does it I believe is this. Heat causes the atoms in the metal to move faster or to have more energy. The more energy something has, the more room each atom needs to function. That may be simplistic, but I think that is the idea.
