Think of a topic of interest to you within the subject of Earth and Space Science. How might the daily activities of a scientist studying that topic or field differ from a chemist, physicist, or biologist? How might it be the same? In what ways would the scientist likely use the scientific method? Which types of data would they likely analyze most often?

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
