The heat capacity of an object indicates how much energy that object can absorb for a given increase in that object's temperature. In a system in which two objects of different temperatures come into contact with one another, the warmer object will cool and the cooler object will warm up until the system is at a single equilibrium temperature. Note the difference between the terms molar heat capacity, which has units of J/(mol⋅∘C), and specific heat, which has units of...

6) EscapeVelocity In order for an object to escape a planet's gravitational pull, it must attain a minimum initial velocity called the escape velocity. The escape velocity varies from planet to planet but it is the same for all objects on a given planet. Assume that we are analyzing the data that a small probe has collected while exploring some mystery planet. The probe has managed to obtain the circumference of the planet and the acceleration due to gravity at...
