76Lapse rate — The lapse rate is defined as the rate of decrease with height for an atmospheric variable. The variable involved is temperature unless specified otherwise.[1][2] The terminology arises from the word lapse in the sense of a decrease or decline;… …
77Isothermal process — An isothermal process is a thermodynamic process in which the temperature of the system stays constant: Delta; T = 0. This typically occurs when a system is in contact with an outside thermal reservoir (heat bath), and processes occur slowly… …
78Molten salt reactor — scheme. A molten salt reactor (MSR) is a type of nuclear fission reactor in which the primary coolant, or even the fuel itself is a molten salt mixture. MSRs run at higher temperatures than water cooled reactors for higher thermodynamic… …
79airplane — /air playn /, n. 1. a heavier than air aircraft kept aloft by the upward thrust exerted by the passing air on its fixed wings and driven by propellers, jet propulsion, etc. 2. any similar heavier than air aircraft, as a glider or helicopter. Also …
