How much energy must be supplied to turn 1 gram of water at 100 degrees centigrade to steam at 100 degree centigrade?

Heat of vaporization of water is 2.26 x 106 joules per kg.
Therefore 1 gram of water will need 2.26 x 103 joules.

Why the internal energy of gases is zero at -41 degree centigrade?
It is not zero so the question is based on a false assumption.
Can heat be measured in Kelvin or centigrade degrees?
No. Those are units of temperature. Heat is measured in units of energy, such as the joule.
How much time did it take for the water to reach 100 degrees celsius?
That depends on the amount of water, on how cold it was initially, and on how fast heat energy is supplied.
2 examples for temperature metric units?
Three temperature scales are in common use in science and industry. Two of those scales are SI metric: The degree Celsius (°C) scale was devised by dividing the range of temperature between the freezing and boiling temperatures of pure water at standard atmospheric conditions (sea level pressure) into 100 equal parts. Temperatures on this scale were at one time known as degrees centigrade, however it is no longer correct to use that terminology. [The official name was changed from "centigrade degree" to "Celsius degree" by the 9th General Conference on Weights and Measures (CGPM) in 1948.] The kelvin (K)temperature scale is an extension of the degree Celsius scale down to absolute zero, a hypothetical temperature characterized by a complete absence of heat energy. Temperatures on this scale are called kelvins, NOT degrees kelvin, kelvin is not capitalized, and the symbol (capital K) stands alone with no degree symbol. [The official name was changed to "kelvin" and symbol "K" by the 13th General Conference on Weights and Measures (CGPM) in 1967.] The degree Fahrenheit (°F)non-metric temperature scale was devised and evolved over time so that the freezing and boiling temperatures of water are whole numbers, but not round numbers as in the Celsius temperature scale.
How many btus does it take to raise half pound of water 1 degree?
One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.
1560 degree centigrade equals how much calorie?
You can't convert units of temperature to units of energy.
Why steam at 100 degree centigrade produces more severe burns then boiling water at 100 degree centigrade?
Steam has enough kinetic energy to leave the liquid water that is boiling, so it's greater amount of energy results in more severe burns than boiling water, which has a lower amount of energy.

It is not zero so the question is based on a false assumption.
Can heat be measured in Kelvin or centigrade degrees?
No. Those are units of temperature. Heat is measured in units of energy, such as the joule.
How much energy is required to raise the temperature of one liter of water 1 degree centigrade?
The specific heat of water is 4.179 Joules per gram per degree Centigrade. The density of water is 1 gram per cubic centimeter, so one liter is 1000 grams. This means it takes 4179 Joules to raise one liter one degree Centigrade.
How much energy is needed to heat 50 liters of water to 50 degree centigrade?
300 calories, which is equal to about 1255.2 joules
What is the science definition for calorie?
A calorie is the amount of heat required to warm 1 gram of water one degree Centigrade. A Calorie spelt with a big "C" is a kilocalorie and is used in evaluating food energy. It is the heat required to raise 1 kilogram of water one Centigrade degree. On an energy basis a calorie is 41 840 000 ergs.
Do you use thermal energy every day?
Yes, your body uses a thermal energy known as caloric energy called "calories." A calorie is the amount of thermal energy required to heat one gram of water by one degree centigrade.
How do you get -300 centigrade temperature?
You cannot. Absolute zero (the temperature at which there is no thermal energy in an atomic lattice) is −273.15 degrees centigrade, or 0K (K = Kelvin). To reach this exact temperature is impossible, but by use of a "cryocooler" temperatures very near it can be reached.
How much energy required to heat 100 liters of 30 degree centigrade water to raise 135 degree centigrade?
4186 Joules per liter per deg C. Not clear if we are raising the temperature BY 135 deg or TO 135 deg. So the answer is 4186 x 100 x rise in temperature. (Joules).
Twenty percent of the world's energy is supplied by?
Twenty percent of the worlds energy is supplied by natural gas.
Is less energy needed for objects with high specific heat capacity?
More specific heat means you need more heat energy to, for example, raise one kilogram of a substance by one degree centigrade.
