If the sample is at 100 0C, at standard pressure, no supplementary heating is necessary.
==============================
A similar but more detailed take:
Water's latent heat of vaporization is listed as 2,260 kJ/kg = 2.26 J/gram
Since your sample of H2O is in equilibrium right now and sitting there with the uniform
temperature of 100°C, it's ready to vaporize the next time some energy is added,
no matter how little.
Let's say an additional 0.1 Joule comes along and is absorbed. Some little tiny
mass of water ... 0.1/2.26 gram in this example ... must change phase and turn
to vapor. There will be a small blurp in the beaker as the vapor rises, the
surface of the liquid will be disturbed, and anyone watching will report that
it has 'boiled'.
To change the phase of the entire 46.0 grams and turn it to vapor would require
46 x 2.26 = 103.96 Joules.

What is the specific heat of liquid water?
The specific heat of liquid water is approximately 4.18 Joules per gram degree Celsius (J/g°C).
A particular sample of iron requires 562 Joules to raise its temperature from 25 degreee Celsius to 50 degrees Celsius. What must be the mass of the sample of iron?
To find the mass of the iron sample, you need to know the specific heat capacity of iron. Given that the heat energy required to raise the temperature is 562 Joules, you can use the formula: heat energy = mass x specific heat capacity x temperature change. With the specific heat capacity of iron (0.45 J/g°C), you can calculate the mass of the iron sample.
How To calculate Specific Heat of A compound Such as NaOH?
To calculate the specific heat of a compound like NaOH, you would need to know the mass of the compound and the energy required to change its temperature by a certain amount. The formula to calculate specific heat is: specific heat = (energy applied)/(mass * temperature change). Once you have these values, you can plug them into the formula to find the specific heat of the compound.
What is the amount of thermal energy needed to raise the temperature of 1 kg of a material 1 degree celsius?
The amount of thermal energy needed to raise the temperature of 1 kg of a material by 1 degree Celsius is known as the specific heat capacity of the material. It varies depending on the material, but for water, which has a specific heat capacity of 4.184 J/g°C, it would take 4.184 J of energy to raise the temperature of 1 kg of water by 1 degree Celsius.
How many joules of energy are necessary to heat a sample of water with a mass of 46 g?
The amount of energy required to heat a sample of water can be calculated using the formula: energy = mass x specific heat capacity x temperature change. Given that the specific heat capacity of water is 4.18 J/g°C, and assuming a temperature change of 1°C, the energy required would be 46 g x 4.18 J/g°C x 1°C = 192.28 J.
What is the amount of energy needed to change the temp of a substance called?
The amount of energy needed to change the temperature of a substance is known as heat. It is measured in units such as calories or joules. It takes a specific amount of heat energy to raise the temperature of a substance by a certain number of degrees Celsius.
What ocean temperature is necessary to provide the energy for hurricane information?
The temperature of the ocean must be 80 degrees or 26 celsius in order for a hurricane, typhoon or a cyclone form.
What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
What is specific heat capacity equation?
Quantity of Energy= mass x temperature change x specific heat capacity For example: Find the amount of energy needed to raise the temperature of 0.20 kg of lead by 15 degree Celsius if the specific heat capacity of lead is 0.90 J/g degree Celsius. Answer: J=200g x 15 degree Celsius x 0.90 J/g degree Celsius = 2700 J
What is the specific heat of liquid water?

90,000
How many kilojoules of energy are necessary to raise the temperature of 3 kilograms of cast iron from 30 degrees celsius to 120 degrees celsius?
I will use this formula. Some conversion will be required. ( I only know specific heat iron in J/gC ) q(Joules) = mass * specific heat * change in temperature Celsius 3 kilograms cast iron = 3000 grams q = (3000 g)(0.46 J/gC)(120 C - 30 C) = 124200 Joules (1 kilojoule/1000 joules) = 124.2 kilojoules of energy needed ===========================
