If you were able to drill from the surface of the earth to the inner core, what would you observe in terms of temperature, pressure, and density?

The density of a liquid could be found by using

Which of the following best describes internal energy? a. the difference between the kinetic and potential energies of the particles in a system b. the sum of the kinetic and potential energies of the particles in a system c. the sum of the kinetic and thermal energies of the particles in a system d. the difference between the kinetic and thermal energies of the particles in a system

You can melt ice by applying pressure because the solid/liquid line has a slope.
