A KHP solution was made by adding approximately 30 mL of deionized (DI) water to your KHP beaker. The KHP solution was then titrated, and 28.32 mL of a NaOH solution was required to reach the endpoint of the titration. 1.3561 g of an unknown solid was transferred to a clean, dry Erlenmeyer flask, and approximately 20 mL of DI water was added. The unknown solution was titrated, and 17.88 mL of the same NaOH solution was required to reach the endpoint of the titration. What was the %KHP by mass in the unknown sample solid

The flow of heat from Earth's interior to the surface is estimated at terawatts (TW) and comes from two main sources in roughly equal amounts:

radiogenic heat produced by the radioactive decay of isotopes in the mantle and crustprimordial heat left over from the formation of the Earth.                                                                        The other main sources of heat in the deep earth are:Heat from when the planet formed and accreted, which has not yet been lost; Frictional heating, caused by denser core material sinking to the center of the planet Heat from the decay of radioactive elements.
