A calorie of energy (NOT to be confused with a Calorie, they are different so watch the caps) is the amount necessary to heat 1 gram of water 1oC, so 30 calories are needed to heat 30 g of water 1 degree. To heat it 70oC would take 2100 calories (or 2.1 Calories) of energy.

How much heat is needed to vaporize 100g of water at 100 degrees C?
Heat of vaporization at 100 degrees C is 40.65 kJ/mol. 100g water * 1mol/18.015g = 5.55 mol 40.65*5.55 = 225.6452956 = 226 kJ if three sig figs.

What is the name of heat energy that changes ice into water and water into steam?
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
What is the unit of measurement of energy needed to heat one kilogram of water by 2 degrees F?
It is a calorie
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.
Which material will the Sun heat up fastest?
The darkest materialThe material with the largest area (100g of steel wool will heat up quicker than a 100g cube of solid steel)The material with the lowest specific heatThe coldest material (it is easier to heat from 0 to 10 degrees than from 20 to 30 degrees)The material that is isolated the best from it's surroundings
How many btus are needed to heat one lb of water one hundred degrees?
100 BTU if it's Fahrenheit
What is the total number of calories of heat needed to raise to raise the temperature of the liquid water from 20 degrees Celsius to 30 degrees Celsius?
The number of calories required will depend on the mass of water which is to be heated.
Is the heat intensity of water at 100 degrees celsius the same as the heat intensity of water 212 degrees Fahrenheit?
100 degrees celsius are equal to 212 degrees fahrenheit.
