- A cylinder of gas has a temperature of 32F. a) If 205J is added to the system at constant temperature, what is the change in entropy of the system? b) How hot should the gas be in degrees Celsius if the molecules inside are to have twice the kinetic energy?A 2.00-L container has a center partition that divides it into two equal parts as shown. The left side contains 0.044 0 mol of H2 gas, and the right side contains 0.044 0 mol of O2 gas. Both gases are at room temperature and at atmospheric pressure. The partition is removed, and the gases are allowed to mix. What is the entropy increase of the system?*80. D The sun is a sphere with a radius of 6.96 X 10° m and an av- erage surface temperature of 5800 K. Determine the amount by which the sun's thermal radiation increases the entropy of the entire universe each second. Assume that the sun is a perfect blackbody, and that the average temperature of the rest of the universe is 2.73 K. Do not con- sider the thermal radiation absorbed by the sun from the rest of the universe.
- If you are told that the entropy of a system is zero, what do you know about the system?On a hot summer day, 2.00 x 10° J of heat transfer into a parked car takes place, increasing its temperature from 35.5°C to 44.4°C. What is the increase in entropy (in J/K) of the car due to this heat transfer alone? J/K Additional Materials CS Scanned with CamScanner O ReadingThe temperature at the surface of the Sun is approximately 5,600 K, and the temperature at the surface of the Earth is approximately 291 K. What entropy change of the Universe occurs when 4.50 103 J of energy is transferred by radiation from the Sun to the Earth? ____________ J/K
