Chlorine, 15 g, is contained in a vessel with a volume of 0.80 dm3 at 330 K. Calculate the pressure exerted when the chlorine is treated as a perfect (ideal) gas giving your answer in terms of kPa

PV=nRT V=0.8 dm 3 =0.8 x 10 -3 m 3 P= nRT/V R= 8.31 J K -1 mol -1 T= 330 K n= mass/mr n = 15 g/ (2x35.5 g mol -1 ) n = 0.212 mol P = (0.212 mol x 8.31 J K -1 mol -1 x 330 K)/ 0.8 x 10 -3 m 3 P= 726000 Pap=72...

A coil is connected to an analogue centre zero ammeter. A magnet is dropped (North pole first) so that it falls vertically and completely through the coil. What would be observe on the ammeter?

The ammeter's needle would first be deflected one way, then as the direction of the current reversed, it would deflect the other way.
