## How many joules is boiling water?

For water at its boiling point of 100 ºC, the heat of vaporization is 2260 J g-1. This means that to convert 1 g of water at 100 ºC to 1 g of steam at 100 ºC, 2260 J of heat must be absorbed by the water.

## How much energy 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 many joules does it take to boil a gallon of water?

One gallon of water is 3.785 liters, which has a mass, it turns out, of 3.785 kg. The specific heat of water is 4.179 J/(gK), or 4719 J/(kgK). Let’s say that room temperature is about 20 degrees Celsius.

## How many joules does it take to boil a kettle?

The power reading in watts is the energy in joules transferred electrically in one second by the heating element circuit. For the small kettle the rate is about 1,000 joules per second. For large the kettle it is close to 3,000 joules per second.

## How many joules does it take to boil ice?

How many Joules of energy do you need to melt all the ice into a pure liquid along the path from B to C on the graph? Answer: For 1 kilogram of ice ,which equals 1000 grams, we need 333 Joules/gram x 1000 grams = 333,000 Joules. Problem 3 – The Specific Heat of liquid water is 4180 Joules/kg C.

## How many joules would it take to boil 10 g of water?

It would take 200 J of energy.

## How much energy does it take to boil 100 mL of water apex?

So 100ml of water has a mass of 100 grams. The change in temperature is (100°C – 27°C) = 73°C. Since the specific heat of water is 4.18J/g/°C we can calculate the amount of energy needed by the expression below. Energy required = 4.18 J/g/°C X 100g X 73°C = 30.514KJ.

## How do you find joules lost by water?

Multiply the change in temperature by the specific heat capacity and the mass of your object. This will give you the heat lost or gained in joules. Example: If 10 kilograms of water are heated from 10 degrees Celsius to 50 degrees Celsius, how much energy (in joules) did they absorb?

## How many joules does it take to power a house?

A 400 megawatt (400,000 kilowatt) power station is said to be “enough to power 400,000 homes”. That’s because, nationwide, the average home consumer buys about 9800 kilowatt-hours ( 36 gigajoules (GJ).

## How many joules does it take to make an egg?

The yolk of a large egg yields about 250 kJ of energy.
