How many joules are needed to melt 2 grams of water?
2,26 Kj are necessary
How much heat in joules is needed to raise the temperature of 4.0 L of water from 0 degrees Celsius to 70.0 degrees Celsius?
It takes 4.186 Joules to heat one gram of water by 1-degree Celsius. 4.186 * 4000 = 16,744 Joules to heat 4 kilos of water by 1-degree. 16,744 * 70 = 1,172,080 Joules. The above assumes that one litre of water weighs exactly 1 Kilogram.
How much energy is needed to melt 5 grams of ice?
The unit for the heat of vaporization is J/g or Joules per gram of material. The amount of energy required = mass * heat of vaporization = 5.0 g * 5.0 J/g = 25.0 J (Q.E.D.)
The amount of energy an object contains and how fast the particles of matter move is?
Kinetic energy = 1/2mv2, where kinetic energy is measured in Joules, mass in grams, and velocity in m/s.
How do you Convert 40.79 kilojoules per mole to joules per grams?
40.79 H2O kj/moles x 1 moles/18 grams= 2.266/1000=0.002266 joules/grams
How many joules of heat are needed to completely vaporize 24.40 grams of water at its boiling point?
The answer is 55,117 kJ.
What energy is measure in?
A: Energy is measured in joules and kilojoules. One joule is the amount of energy needed to lift 100 grams to 1 kiliogram.
How many joules are in 1500 grams?
Voltage is electrical pressure and Joules is a power rating so other info is needed
How many joules of energy are needed to melt 54-grams of ice at its melting point?
The specific latent heat/ latent heat of fusion of ice is 333.55 J/gtherefore by using the equation E=mLE = 54 * 333.55= 18011.7 JTherefore the energy needed to melt 54 grams of ice at its melting point which is keeping it at 0 degrees Celsius is 18011.7 Joules.
How many joules are needed to melt 2 grams of water?
2,26 Kj are necessary
Is mass measured in joules?
No, a Joule is a unit of energy. Mass is measured in kilograms (or grams)
What is the kinetic energy of an object with an mass of 5 grams and a velocity of 1000ms?
The object's kinetic energy is 2,500 joules.
How many joules are needed to warm 25.5 grams of water from 14.0C to 22.5C?
9.1x10^2J
How many grams of camphor are needed to raise the boiling point of 43.5 grams of benzene by 2.10 Celsius?
5.2

The specific heat of gold is 0.131 Joules per gram. Celsius How much energy is required to heat 1.3 grams of gold from 25 Celsius to 46 Celsius?
0.131 joules/gram'C x 1.3 grams x (46-25)'C = 3.5763 joules
How many joules of energy are necessary to heat a sample of water with a mass of 46.0 grams for 0.0?
46 calories (or 192, 464 joules) for each Celsius degree.
