Predict the changes in atomic motion within a sample as the material sublimes. a) the atomic motion within the sample increases as the material sublimes. eliminate b) atomic motion within the sample will decrease as the material sublimes. c) changing phases through sublimation has no effect on the atomic motion. d) sublimation divides the atomic motion of the sample by the phase change.

If you put a helium-filled balloon in the refrigerator, what will happen?

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
