How much energy does it take to boil 1 Litre of water?

How many watts does it take to boil water?

The specific heat capacity is in the equation. If it takes 1 min to boil the water, it will take 1600 watt hours or 1.6 kilo watt hours.

How much energy does it take to boil 100g of water?

How much energy does it take to boil 100g of water? To convert 100.0 g of water at 20.0 °C to steam at 100.0 °C requires 259.5 kJ of energy.

Is it cheaper to boil water with gas or electric?

Because gas is cheaper than electricity, it works out slightly cheaper to boil water on a gas hob than using an electric kettle, as long as you are boiling just the quantity you need and switch off the hob as soon as it has boiled.

How much energy is required to boil 150g water?

= 150 g x 4.184 J/g/K x (373 – 298) K = 47,070 J. Thus, 47,070 J are needed to increase the temperature of 150 g of water from 25 degrees C to its boiling point of 100 degrees C. One can follow a similar procedure to determine the energy needed to heat water from one temperature to another.

Why is energy needed to boil water?

Boiling water is an endothermic process, which supplies heat to the water molecules, increasing their potential energy. … Once the intermolecular bonds are broken, any extra heat increases the kinetic energy of the system and the molecules of the water vapor move faster as the temperature increases.

What is the most efficient way to heat water?

For appliances – microwave, electric tea kettle, electric stovetop – the most efficient appliance is the one that can boil water while pulling in the least amount of electricity via its plug.

How long should it take a gas stove to boil water?

So, How long does it take for water to boil? 1 liter of ordinary tap water will boil after 6-8 minutes at a gas stove and from 9 to 12 minutes at the electric stove. If the water is pure, it will be 6 minutes at a gas cooker and 8 minutes at an electric stove.

Does it take longer to boil water on a gas stove?

Boiling speed.

In comparison tests, gas stoves are almost always slower to boil a pot of water than an electric stove with the same BTU rating. This is probably because a lot more heat escapes with gas (see below).
