Calculate the following: a. The bubble point temperature of a liquid mixture with a molar composition of 55.0 mol% n-hexane and 45.0 mol% n-heptane at 1.00 atm and the composition (mole fractions) of the vapor in equilibrium with this mixture.
b. The dew-point temperature of a gas mixture with a molar composition of 30.0% n-hexane, 15.0% n-heptane, and 55.0% air at 1.00 atm and the composition (mole fractions) of the liquid in equilibrium with this mixture.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
