100 grams of oxygen and 100 grams of hydrogen gas occupy separate, equal sections of 200 liter tank. The divide is removed and the gases are allowed to mix and react with each other. The temperature is kept constant at 110 °C, throughout the process
a) find the pressure of each gas in the separate containers
b) find the pressure after the reaction ends.
Can the atoms in a liquid helium at 4K (interatomic distance about 0.1 nanometer) be adequately represented by nonspreading wave packets, so that their motion can be described classically.
The air passes through a large-diameter glass tube, then through a small-diameter tube, and nally through a large-diameter tube again. Find the velocity of the air in the small-diameter tube

Two 0.80g spheres are charged equally and placed 2.0cm apart. When released, they begin to accelerate at 160m/s^2. What is the magnitude of the charge on each sphere?
If one of the crystal faces is matted (flat or reflecting) draw a picture and show how the x-rays travel, reflect and diffract on the first 2 layers of the atoms. Indicate the position of the detector in relation to the source and the crystal.
