Calculate the heat capacity of a gas sample from the following information: the sam- ple comes to equilibrium in a flask at 25°c and 121.3 kpa. a stopcock is opened briefly, allowing the pressure to drop to 101.3 kpa. with the stopcock closed, the flask warms, returning to 25°c, and the pressure is measured as 104.0 kpa. determine cp in j·mol−1·k−1 assuming the gas to be ideal and the expansion of the gas remaining in the flask to be reversible and adiabatic.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
