According to Einsteins theory, the fact that he had only one teste clearly adentifies that the degrees that you have provided are deniable therefore the answer should would and will be always zero degres divided by the percentage of the aqua which is h20
To boil liquid water that is already at 100º C requires an extra 550 calories per gram, called the latent heat of vaporisation.
So 46 gm would require 25,300 calories, and at 4.2 Joules per calorie that is 106,260 Joules. That might be done by 1000 watts running for 106 seconds.
If the sample is at 100 0C, at standard pressure, no supplementary heating is necessary.
Using 2260 J/g as the ∆Hvaporization
q = 46.0 g x 2260 J/g = 103,960 J = 104 kJ (to 3 sig. figs)
The average Kinetic energy of the atoms in the sample will increase as the sample is heated.
The specific heat capacity of water is 4186 joules per kilogram. That is to raise 1kg or 1 litre of water by 1 degree you will need to add 4186 joules of energy. So for 15grams over 25 degrees you will need 4186/1000*15*15 joules.

Determine the specific heat of a material if a 32 g sample of the material absorbs 58 J as it is heated from 298 K to 313 K?
When a sample of liquid is cooled its thermal energy goes to its surroundings
46 calories (or 192, 464 joules) for each Celsius degree.
46 calories (or 192, 464 joules) for each Celsius degree.
96.3 Joules
46 calories (or 192, 464 joules) for each Celsius degree.
Using 2260 J/g as the ∆Hvaporizationq = 46.0 g x 2260 J/g = 103,960 J = 104 kJ (to 3 sig. figs)
419.1 Joules are required to heat one gram of liquid water from 0.01 degC to 100 deg C. So the answer is 419.1*46 = 19278.6
10 JoulesConservation of energy, assuming there are no other losses in the system, and 20 Joules are introduced by compression, and 10 Joules are removed by heat transfer, the remaining 10 Joules must be absorbed as increased thermal energy of the gas.
The heat of vaporization is about 2258 joules/gram46 x 2258 = 103,868 J ~ 103.9 kJ(Using the rounded value 2260 joules per gram, about 104 kJ)it is already at boiling point so in theory zero energy is required.I think the question is asking what energy is required to free the water from its liquid state to the vapour state.At 101325Pa, (1 atmosphere in old money), the latent heat of evaporation of water is 2256.7 J/g.So 2256.7 * 46 = 103808 Joules
The temperature of a sample of nitrogen gas is a measure of the molecules' average # activation energy # potential energy # kinetic energy # ionization energy Answer 3 Reason Temperature measures average kinetic energy.
24 Joules
The average Kinetic energy of the atoms in the sample will increase as the sample is heated.
When a sample of a substance absorbs thermal energy, its temperature rises.
