A sample of 260.0 of liquid water is initially at a temperature of 75.0ºC. If that water is heated by the combustion of 26.00 grams of coal (carbon) to form carbon dioxide. Assume all the heat from combustion goes into the water. Determine the final state and temperature of the H2O. Explain the determination of the energy produced by combustion of the coal, the amount of energy used to heat the liquid water, the energy needed to vaporize the liquid water, and the final temperature determination.

Principal Quantities and EOS

A physical quantity represents the physical state of a system. It is expressed as the product of a number and unit. The basic quantities used in science are length, mass, and time. The principal quantities are the quantities that are independent of other quantities.
