Determine the heat in kJ to heat 7.18 moles of ice from -29.286 degrees celcius to -2.357 degrees celcius. the specific heat of ice is 2.03 J/g degrees celcius.

How much heat would be required to raise 499 g of water from 111 oC to 251 oC? (You need to know what physical state water is in for the temperature range we're looking at.) Specific heats of water in different physical states H2O (s) = 0.497 cal/g. oC H2O (l) = 1.00 cal/g. oC H2O (g) = 0.490 cal/g. oC

Specific heat is defined as ___- The amount of energy needed to raise the temperature of 1 g of a substance by 1° K - The amount of energy needed to raise the temperature of 1 g by substance of 1° C - The amount of energy needed to raise the temperature of water by 1° C - The amount of energy needed to raise the temperature of a substance by 1° C

On.figure 1, write the name of each process in the appropriate blank on the diagram ( choose from the following list )
