Why might some n2o condense during this process? a. this is an isochoric process in which the pressure decreases, so the temperature also decreases. b. because of the rapid expansion, heat is removed from the system, so the internal energy and temperature of the gas decrease. c. this is an isobaric process, so as the volume increases, the temperature decreases proportionally. d. with the rapid expansion, the expanding gas does work with no heat input, so the internal energy and temperature of the gas decrease.
