The conditions of a gas change in a steady flow process from 20 degrees C and 1000 kPa to 60 degrees C and 100 kPa. Devise a reversible nonflow process (any number of steps) for accomplishing this change of state, and calculate delta U and delta H for the process on the basis of 1 mol of gas. Assume for the gas that PV/T is constant, Cv= (5/2)R, and Cp=(7/2)R.
The total molarity of acid and conjugate base = 0.100M. A boy adds 4.20 milliliters of a 0.370 M solution to the beaker. Determine how much will the pH change?
Suppose that a sample of gas occupies 192 mL of volume at 25C and a pressure of 206 torr. What would be the volume if the pressure were changed to 506 torr at 25C.
Protons can be accelerated to speeds near that of light in particle accelerators. Estimate the wavelength (in nm) of such a proton moving at 2.90 X 108 m/s. (Mass of a proton=1.673 X 10-27 kg)
