,, 3 DEPARTMENT OF PHYSICS AND CHEMISTRY REACTIONS Cutey Bray: The difference between a hydroxide and hydrogen mon- oxide is that one is OH and the other is HO? Mr. Vaill, what is a 1H?11'1OlHE't6'1'?,, Wally: HA manometer, sir? Why, a mano-meter is a modern mechanical appliance for measuring men. HEAT One form of heat is that of a confused oscillatory disturbance of the particles of a bodyg in virtue of this molecular movement, a body may appear to our cut.aneous sense of heat fa sense quite distinct from that of touchj to be more or less hot or warm, or in the converse case, it may, on account of the absence of this movement, appear cold. It is the only form of heat for the perception of which we are endowed with special sense organs. We do not directly perceive the undulations of radiant heat, but When the sun shines on us, heat Waves strike the skin, throwing it into vibrations, and the sensible heat of the skin, and not the radiant heat of space, affects the appropriate nerve-centers by communicating its oscillations to the nervous system.

Why, torque is measured in ohmsf, Prof: '6Well, what is a megohm P Pret: 'GI don't know that, sir. Prof: 4'It,s a million ohms. Now, whatis a Coulomb P Pret: uThat's a thousand ohms, sirf' 'IRI12 Keisker, how would you measure the resistance of that coil of wire P93 The Dutchman: 4'I,d put current in one end and see how much came out the other. 1 W 5 Pwmlz Q: I I Q f N i-J ' T-ra A 5' k lf - ff!
