A particle with the mass of a proton is trapped in a box. The particle falls from the state to the state and emits 0.16 meV of energy. What is the size of the box? (nm)
Estimate the ratio of molar stream flow rates L/V exiting the flash chamber
Calculate the mass flow rate of distillate and bottom product per hour - the mass flow rate of liquid entering the reboiler and the vapour leaving the reboiler per hour.
A sealed rigid tank is filled with 1 kg of steam at 200 °C and 10 bar. What is the volume of the tank? 0.5 kg of steam are removed from the tank. If the temperature remains at 200 °C, what is the new pressure in the tank?
1. In this problem, you learn how to apply the energy balance to a closed system containing an ideal gas with constant Cpfor 3 different processes.
Considering the following equation, how much energy would be released if 10.0L of hydrogen gas were reacted (at STP, 22.4L/mol)?
Nitrogen gas initially at 8.5 bar expands isentropically to 1 bar and 423.15 K (150°C). Assuming nitrogen to be an ideal gas, calculate the initial temperature and the work produced per mole of nitrogen.
It is required to produce an aqueous LiCl solution by mixing LiC1.2H20(s) with water. The mixing occurs both adiabatically and without change in temperature at 298.15 K (25°C). Determine the mole fraction of LiCl in the final solution
The masses of the solutes in each of the solutions are the same. When the solutions are added together, a blood-red precipitate forms. After the reaction has gone to completion, you dry the solid and find that it has a mass of 331.8 g.
What is the final temperature of the calorimeter contents? Explain how this relates to the answer of exercise 88.
For a satellite cruising in a circular orbit at an altitude of 500 km, determine the period of revolution, the flight speed, and the energy expended to bring a unit mass into this orbit.
This cross-linking brings about a stiffening of the rubber by anchoring and thereby preventing intermolecular movement of rubber springs.
Determine the speed at which the machine runs as a motor.
