Why does Water Take So Long to Boil?

Does Salt Help Water Boil Faster?

It’s just a myth that a handful of salt helps water to boil faster. But practically, salt does not help water to boil faster.

Rather, it increases the boiling point of water. Salt only helps in cooking the food faster by making the water hotter.

How Much Energy is Required to Make Water Boil?

Generally speaking, 2257kJ/kg energy is required to make water boil. More precisely, 4J energy is required to boil a gram of water.

Factors Affecting the Time It Takes to Boil Water

The following factors affect the boiling point of water.

1. Pressure Atmospheric

The higher atmospheric pressure increases the boiling temperature of the water. That’s why; people use pressure cookers at higher altitudes to cook food.

2. Impurities

Impurities also increase the boiling water temperature. Impurities make the liquid denser. It requires a greater amount of energy to make the water roll boil.

3. Heat Source

Heat source also affects the boiling point of water. If you’re using a microwave as a heat source, water will be boiled very easily within 2-3 minutes.

4. Quantity of Water

Less quantity of water leads the water to boil fast. The larger quantity of water makes it difficult to boil and requires more heat and energy.

How Long Does it Take to Boil 2 Quarts, 4 Quarts, 6 Quarts, and 12 Quarts of Water?

Below a table compares the boiling time for different quantities of water.

               Quantity                                                                         Time

                      2 quarts                     1-2 minutes
                     4 quarts                     2-4 minutes
                     6 quarts                     5-6 minutes
                    12 quarts                     8-10 minutes

How Long Does it Take for Water to Boil in an Electric Kettle, Microwave, and Stove?

The boiling of water depends upon the source of heat. The boiling time for different heat sources is mentioned below.

Electric Kettle

Electric Kettle provides more heat to water, making the water hotter rapidly. Generally, 1 liter of water boils within 4-5 minutes in an electric kettle.


It is the fastest way to boil water using a safe microwave container. It takes 2-3 minutes to make 1 liter of rolling water boil in the microwave.


Most people use propane stoves for heating water. 1 liter of water or 4 cups of water is boiled in 6-8 Minutes on a gas stove. And it takes 10-12 minutes to boil 1 liter of water on an electric stove.

Everything You Ever Wanted to Know about Boiling Water Time

· It’s just a myth that a pinch of salt makes the water boil faster.

· At higher altitudes, air molecules become less dense. Water molecules require less energy to break their bonds. The result is, at higher altitudes boiling time of water decreases.

· A gazed water pot will never boil. (Isn’t it cute?)

· The quantity of water also affects the boiling time of water.

· Heat source plays a vital role in increasing or decreasing the boiling time of water.

· Boiling time also depends upon the nature of the water. Boiling time varies for faucet water and filtered water.
