A 2.52 L volume of hydrogen measured at −155 °C is warmed to 100°C. Calculate the volume (in L) of the gas at the higher temperature, assuming no change in pressure.

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?  

The correct answer is c. orbital shape. "the angular momentum quantum number l describes the shape of an orbital. it corresponds to each orbital type, i.e. (0,1,2,−1)=(s,p,d,f,g,"

Depends on the speed of the car.
