Water takes a long time to boil due to its specific heat. Wikipedia answers it with a lot of science (see link) http://en.wikipedia.org/wiki/Specific_heat_capacity
but I have a slightly easier way of explaining it.
So, we're dealing with two actual processes going on here.
1) First, you're raising the temperature of the water from whatever it starts at to 100 degrees C (212 degrees F). Specific heat is a scientific formula that tells you how much energy it takes to increase one litre of something by one degree celsius, and water takes a whole bunch of energy. Metal has a low specific heat, its really easy to warm it up. You can hold a teaspoon of water in one hand, and a penny in the other, and the penny will feel warmer quicker, but it also will cool quicker.
2) The second process is changing the phase of water, from a liquid to a gas. It takes a LOT of energy to change something form a solid to a liquid, or from a liquid to a gas.

Can you boil water if you pass electric current through it?
Yes, we can boil water if we pass enough current through it......
How long is the electric water heater can boil a glass of water?
An electric water heater typically takes around 5-10 minutes to boil a glass of water, depending on the volume of water and the power of the heater.
Can you boil eggs in an electric fry pan?
You can't boil eggs in an electric fry pan. An electric fry pan needs to be plugged in and shouldn't be near water.
How does the electric jug work?
the element makes the water boil
Why does it take so very long to get water or soup to boil in aluminum ware on electric range?
Cause aluminum easily transfers energy to air molecules.
Do larger amounts of water take longer to boil?
Yes
What are the main uses for electric range cookers?
The main use for an electric range cooker is primarily to cook products for consumption. These cookers can be used to fry, boil and poach as well as bake.
Why does it take a less time to boil little ammounts of water?
It takes less time to boil little amounts of water because there is less water to boil. The more water in the pot, the longer it takes to heat up.
Will water with salt evaporate faster than water without salt experiment?
Water with salt will actually take longer than water without salt to evaporate. This is due to boiling point elevation. If you put a solute into water, it will make it more difficult to boil, and therefore will boil at a higher temperature. Since it takes longer for the salt water to boil, it will take longer for it to evaporate as well
How much salt do you put in to make the water boil faster?
Adding salt to water actually increases its boiling point, so it will take longer for saltwater to boil compared to plain water. It is not recommended to add salt solely to make the water boil faster.
What do you use to boil water?
You can use a stove, electric kettle, or microwave to boil water. Each method has its own advantages in terms of speed and convenience.
Why does salt water take longer to boil?
The boiling point is increased after adding impurities to water.
