Addition of heat at constant pressure to a gas results in Raising its temperature and doing external work
When you heat a gas, both its vapor pressure and the volume it occupies increase. The individual gas particles become more energetic and the temperature of the gas increases.
Which of the following items is not a path function?
Heat and work are path functions because they depend on how a sysem changes from initial to final state, hence they are state functions. Thermal conductivity is mainly a function of the motion of the free electrons therefore property of a material, not a path function.
An actual engine is to be designed having same efficiency as the Carnot cycle. Such a proposition is
Correct Option is (B)
The lower the temperature, the lower the pressure inside of the sphere. If the exact values were plotted out, a linear relationship would be apparent. Extrapolating this line to the point where there would be no pressure yields absolute zero, which is about -273.15 degrees Celsius.
Molecular volume of any perfect gas at 600 × 103 N/m2 and 27°C will be
A homogeneous thermodynamic system is defined as the one whose chemical composition and physical properties are the same in all parts of the system, or change continuously from one point to another. An example of a heterogeneous system is water with ice floating in it. This system has two homogeneous bodies, water and ice. The chemical composition of the two phases is the same, but their physical properties differ drastically
