A glass ball of volume 1.9m3m3 is connected a U-shaped tube with one end open to the atmosphere. The tube is filled with a liquid of density 4097 kgm3kgm3. 71.3 moles of a monatomic ideal gas are inside the glass ball. The liquid is a height 1.5cm above the bottom of the tube on the side closer to the atmosphere, and 15.6 cm above the bottom of the tube on the side of the glass ball. Atmospheric pressure is 1.03914×105Pa×105Pa....
A long cylindrical gas-tight tube, with a sound source at one end and sensor at the other
1. A long cylindrical gas-tight tube, with a sound source at one end and sensor at the other, was constructed to measure the speed by recording the time it take a sound wave to travel the length of the tube (see diagram). i. Initially, the tube was filled with air at atmospheric pressure (P=1.012x105Pa & T=295.2K). When a sound wave is produced by the source, the elapsed time for the wave to reach the sensor was 3.64x10-3s. Determine the length of...
