Is the amount of heat required to boil 1kg of water equal to the amount of heat required to melt 1kg of ice?
No, the amount of heat required to boil 1kg of water is much higher than the amount of heat required to melt 1kg of ice. Boiling water requires additional heat to overcome the latent heat of vaporization, while melting ice only requires heat to overcome the latent heat of fusion.

How Much energy does it take to boil 100 ml?
The energy required to boil 100 ml of water at room temperature (20°C) to boiling point (100°C) is about 4200 joules. This is the amount of energy needed to raise the temperature of water by 1°C per gram.
What is the latent heat of fusion?
The amount of energy it takes to boil a substance
Does water boil at a lower level above sea level?
First understand that the boiling of water occurs when the energy of water molecules is equal to the vapour pressure... (i.e energy of water is equal to the external pressure due to the atmosphere)... above sea level the atmospheric pressure is lower hence low energy is required... hence water boil at low temperature...
Why won't water boil at high altitudes?
At high altitudes, the air pressure is lower, which causes water to boil at a lower temperature. This is because the lower pressure reduces the amount of energy needed for water molecules to escape into vapor form, making it boil at a lower temperature than at sea level.
How many minutes does water needs to boil?
There are variables involved. You need to know the amount of water, its initial temperature, the amount of heat being applied and the ambient temperature.
Will water boil faster if there is less of it?
A small amount of water will reach it's boiling point sooner than a large amount of water. It will not boil faster.
How many natural gas therms are required to boil water?
The amount of natural gas therms required to boil water depends on the volume of water and the efficiency of the heating system. On average, it takes about 0.12 therms to heat a gallon of water, but this can vary based on factors like starting water temperature and insulation of the heating system.
The large amount of heat required to melt ice and boil water are due to?
The large amount of heat required to melt ice and boil water is due to the energy needed to break the intermolecular bonds that hold the water molecules together in a solid or liquid state. This process absorbs energy and increases the temperature until the phase change is complete.
The temperature required to boil water at?
100 degrees Celsius
What is the boiling of water in degrees celsius?
The amount of heat needed to boil water varies with the air pressure. Water in a vacuum will boil at room temperature.
Why do you put lids on pans?
The use of a lid when cooking reduces the amount of heat escaping from the cooking area. Reducing the amount of time required for cooking and thereby reducing the amount of energy needed. This in turn reduces the amount of energy-required to pay the electricity bill. A good way to prove this point is to boil a pot of water with a lid and one without a lid and time how long they take to boil. Then see how much difference there is in the setting needed to make each simmer.
What volume of water can be boiled by 3 kJ of energy?
The energy required to boil a volume of water depends on the initial temperature and pressure. Generally, 3 kJ of energy can boil a small amount of water, around 0.1-0.2 liters, if starting at room temperature and pressure.
How Much energy does it take to boil 100 ml?
The energy required to boil 100 ml of water at room temperature (20°C) to boiling point (100°C) is about 4200 joules. This is the amount of energy needed to raise the temperature of water by 1°C per gram.
How long does it take for water to boil at Fahrenheit?
The time required to get water to boil depends upon the water initial temperature, the water mass, the nature of the heat source, the net heat transfer rate to the water, and the local barometric pressure.
Does the larger the quantity of water result in a higher temperature at which the water will boil?
Technically speaking, boiling is when the pressure inside the system is equal to that of the surroundings. That means that you can boil water at room temperature if you have a vacuum pump. If you mean just to the heat that it starts to boil at STP, then no, it doesn't. Boiling point at STP is and always will be 100 degrees Celsius.
Does amount of water effect how long it takes to boil?
Yes. The more quantity of water there is the more time it takes to boil than a less quantity of water. No I don't think so because it depends on the temperature on which it is the boiled.If it is more,then the water boils fast. Of course if it is more water,then it needs more temperature than less quantity of water.
