Why does your gas range take longer than electric to boil water?

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......
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.
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.
How does the electric jug work?
the element makes the water boil
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
Why does salt water take longer to boil?
The boiling point is increased after adding impurities to water.
Why does it take the water longer to boil when it has salt in it?
impurities rise the boiling point
Why does plain water boil faster than salt water?
Salt changes the molecular composition of the water, causing its boiling point to go up. That's why it takes it longer to boil.
Are there things the makes water boil faster or slower?
If you have a kettle, the more water you put in, the longer it takes.
