When 25.9 j was added as heat to a particular ideal gas, the volume of the gas changed from 41.0 cm3 to 67.5 cm3 while the pressure remained constant at 1.08 atm. (a) by how much did the internal energy of the gas change? if the quantity of gas present is 1.66 x 10-3 mol, find the molar specific heat of the gas at (b) constant pressure and (c) constant volume.

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?
