If the car's windows were to be left open, it would be less hot but still be hot if the rays of the sun were directly on the car.
Actually, you do NOT need to calculate the number of moles, so you do NOT need to convert the volume and pressure. (You DO have to convert the temperature.) That's because for this problem, pV/T is constant, so the units cancel (but the temperature scale matters).
<span>200kPa * 15L / 373K = 101kPa * V / 273K </span>

X-rays have much shorter wavelengths and higher frequencies. Likewise, red light has a longer wavelength than blue light.
