A lift on Mars for unloading spacecraft has a height of 8 feet [ft], and a floor area of 10 feet [ft] wide by 6 feet [ft] long.    The lift floor is made of a thin sheet-metal that has a maximum pressure rating of 0.5 pounds-force per square inch [psi]. A crate of material of with a mass of 5000 pounds-mass [lbm] on Earth, with measurements of 4 feet[ft] high by 8 feet [ft] wide and 4 feet[ft] long , is shipped to Mars. The acceleration due to gravity on Mars is 3.7 meters per second squared [ms2]. Can the crate be safely removed from the spacecraft once it reaches Mars using the lift?  To support your answer, determine the pressure of the crate in units of pounds-force per square inch [psi]

Chemical and Phase Equilibrium

Phase diagrams or equilibrium phase diagrams are the graphical representations that show the phase transformations of the constituting elements with respect to the pressure, temperature, and compositions. The diagrams show the conditions that limit the different phases, namely solid, liquid, and gas. The diagram can also be utilized to verify the relations between the state variables. Most of the phase diagrams are temperature-pressure phase diagrams, with the variable parameter as the composition. Usually other variables such as solubility and pressure parameters are not indicated in the phase diagram. For a one-component system (unary phase diagram), the phase diagram is generally a function of temperature and pressure as the state variables, or temperature and volume. However, for a binary system (two-phase) having two components, the phase diagram is a function of temperature and composition as the state variables only. Coexisting of the different phases of the constituting elements is indicated in the phase diagram. A ternary phase diagram can be characterized by consisting of three phases in equilibrium.
