Given that white dwarf supernovae are such good standard candles, why don't we use them to measure the distance to all galaxies?
A) They are rare events, so we have observed them in only a tiny fraction of all galaxies. B) They can occur only in spiral galaxies, not elliptical galaxies. C) We would, but we don't have enough telescopes. D) We cannot see them beyond a distance of about 100 million light-years.
A cylinder containing an ideal gas has a volume of 3.0 m3 and a pressure of 1.0 × 10^5 Pa at a temperature of 300 K. The cylinder is placed against a metal block that is maintained at 900 K and the gas expands as the pressure remains constant until the temperature of the gas reaches 900 K. The change in internal energy of the gas is 9.0 × 10^5 J. Find the change in entropy of the block
associated with the heat transfer to the gas. a. 0 c. -1700 J/K b. +670 J/K d. -1100 J/K
