The escape velocity of any object from earth is 11.2 km/s. (a) express this speed in m/s and km/h. (b) at what temperature would oxygen molecules (molecular mass is equal to 32.0 g/mol) have an average velocity v_{rms} rms equal to earth’s escape velocity of 11.1 km/s?

First answer marked as brainiest which is the correct equation describing the first law of thermodynamics? a) when the internal energy of a system changes, it equals the amount of heat added plus the work done. b) when work is done by the piston, it is equal to the heat added plus the change in internal energy of the system. c) when heat is added to the system, it is equal to the amount of work done by the piston plus the change in internal energy of the system.
