n = 3.10 mol of Hydrogen gas is initially at T = 388 K temperature and pi = 1.76×105 Pa pressure. The gas is then reversibly and isothermally compressed until its pressure reaches pf = 7.75×105 Pa. What is the volume of the gas at the end of the compression process?
How much work did the external force perform?
How much heat did the gas emit?
How much entropy did the gas emit?
What would be the temperature of the gas, if the gas was allowed to adiabatically expand back to its original pressure?
The aurora is caused when electrons and protons, moving in earth's magnetic field of 5x10^-5 T, collide with molecules of the atmosphere and cause them to glow. What is the radius of the circular orbit for (a) an electron with speed 1.0×10^6 and (b) ..
The depth of water behind the Hoover Dam in Nevada is 220 m. What is the water pressure at base of this dam? (Neglect the pressure due to the atmosphere.)
