Because the evaporation of water carries heat away from the fire.
Water has a high specific heat capacity. This is a measurement of the amount of energy required to cause a unit volume of a material to increase by a unit temperature. As such you must add a lot of energy to water to cause a small increase in temperature.
For example to increase the temperature of 1 litre of water by 1 degrees C, you must add 4181.3 joules of energy.

What melts hard snow?
Hard snow can be melted by applying heat, such as using a snow-melting solution that contains salt or chemicals designed to lower the freezing point of water. Other methods include using hot water, heating elements, or simply waiting for the sun to warm and melt the snow.
What holds heat longer soil or water?
Water holds heat longer than soil. This is because water has a higher specific heat capacity than soil, meaning it requires more energy to heat up or cool down compared to soil. As a result, water can store more thermal energy and retain heat for a longer period of time.
Where did the heat come from to evaporate water from sea water?
The main source of heat is from the sun.
What will be the flow of heat when you drop a block of ice in boiling water?
When you drop a block of ice in boiling water, heat from the water will transfer to the ice, causing the ice to melt. The heat will continue to transfer from the water to the ice until the ice completely melts and reaches the same temperature as the water.
When you heat water it does what into water vapour?
When you heat water, it evaporates into water vapor, which is a gas form of water. This process occurs when the water reaches its boiling point and changes from a liquid to a gas.
Why is it hard to get water in hot countries?
because the heat dries up all of the water in the ground
Why do we need to hard boil and egg?
An egg, a heat source, a container, water
Why is water a good choice to heat something?
Water has a high heat capacity by mass and volume, and is very easy to manipulate reagrdless of state.
Why is water an excellent material to use in a calorimeter?
Water is an excellent material to use in a calorimeter because it has a very high specific heat, making it very hard for water to raise its temperature even by 1 degree celsius, but as hard as it was to raise the temperature of the water, it is equally as hard to lower the temperature of the water-making it able to effectively retain heat and allowing the other material inside of the calorimeter to absorb that heat.
Why wont a 1993 Cadillac De ville heat properly?
because you don't have enough water in system it is very hard to get enough water in the system you have to keep adding water
How does the presence of hard water affect the process of boiling water?
The presence of hard water can affect the process of boiling water by causing mineral deposits to form on the heating element or inside the pot. This can reduce the efficiency of heat transfer and increase the time it takes for the water to reach boiling temperature.
Perfect hard boiled eggs?
Place eggs in a large pot. Cover with 2 inches of cold water. Heat over medium high heat until water begins to boil. Once boiling, turn off the heat, cover the pot and let sit for 12 minutes. Rinse the eggs with cold water
Does it take more heat to heat water or to boil water?
It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.
Why is it hard to survive in hot and dry regions?
There isn't much food or water. Also the heat makes you use more energy so you need more food and water
Why is it hard to get across the Sahara Desert?
Because of the lack of food and water also with the extreme heat during the day and extreme cold during the night. Most people die of heat stroke
What melts hard snow?
Hard snow can be melted by applying heat, such as using a snow-melting solution that contains salt or chemicals designed to lower the freezing point of water. Other methods include using hot water, heating elements, or simply waiting for the sun to warm and melt the snow.
Why does a kettle have 800 watts?
Assuming you got that number off an electric kettle it is because that is how much power is needed to heat the water. The number of watts actually measure how much energy the kettle is designed to use. Water is very hard to heat compared to other liquids(or to cool). So it takes a lot of watts to get the kettle to heat the water.
