Please help with this last question Perform conversions between energy units. 8.51×10^6 J = kcal
The work done on an ideal gas is -5.41 x 10^6 J during a process in which the temperature remains constant at 323 C and the volume changes from 2.14 m3 to 7.28 m3? How many moles of the gas are there? Express your result to three significant digits and in scientific notation. Be careful with signs!
Two particles, one with charge -4.61 x 106 C and one with charge 6.91 x106 C, are 0.0584 meters apart What is the magnitude of the force that one particle exerts on the other? Number Two new particles, which have identical positive charge q3, are placed the same 0.0584 meters apart, and the force between them is measured to be the same as that between the original particles. What is q3? Number
If a system has 2.50 x 10 kcal of work done to it, and releases 5.00 x 10' J of heat into its surroundings, what is the change in internal energy (AE or AU) of the system?

Compute the total quantity of heat (both in Kcal and J) required to raise the temperature of 1.00 kg of ice at -10.0 degrees C to 1.00 kg of steam at 110.0 degrees C. Assume no loss of mass or heat in this process. Note that this will requires several computations that must be completely added up, and you must include all phase changes and use the correct specific heats.

Help!!!
Part A If a total of 5.55 x 10% J of heat is added to a mass of 555 g of water which was originally at a temperature of 555°C (and noting that the specific heat of water is 4186 J/kg-K and that the latent heat of vaporization of water is 2.26 x 106 J/kg), then what is the mass of the water that remains (ie. the mass of the water that was not vaporized)? O 335 g 258...
