Engines & Heat Physics Labware

A glass U tube, 15 mm dia, with one limb plain 220 mm long and other limb graduated 25 to 35 x 0.2 ml, 120 mm long terminating in a bulb 38 mm diameter, with third limb 185 x 6 mm (L x D) joined at right angles to the plane of the other two, short length of glass tubing mounted in end of wide bore plain limb with rubber bung, a piece of rubber tube and a pinch clip..
Supplied with tall form beaker 1000 ml and stirrer. 30 ml mercury is required. Supplied without mercury and without thermometer.

Comprising strips of copper, iron aluminium and brass fixed on wooden ring meeting in the centre, outer ends of the strips formed with small cups.

For determining the specific heat of water or similar liquid. Consists of a glass tube 100 mm long with heating element (electric wire).
Two screw terminals are provided at the ends of the tube for electric supply. The horizontal tube is connected by means of rubber bungs to the inlet & outlet system. Each having a vertical expansion to accommodate the thermometer. A stream of water is made to flow through the glass tube & heated by the spiral by passing electric current. With the help of an adjustable constant boil tank, the rate of flow is kept constant. The rise in temperature of water is measured by two thermometers. The whole apparatus is mounted on a polished wooden base approx. 625 x 130 mm in size. Supplied with thermometer.

Comprising partly evacuated glass bulb approx. 70 mm. diameter, containing at its centre a fine pivot which supports four light weight metal arms.
One side of each vane is blackened, the reverse side is bright. Mounted on round base

One cylinder, 4 cycled and double valve system gas engine, to show operations like intake, compression, explosion, exhaust, spark and others, mounted on wooden base with spark plug and battery.
