Compound Bar

Description

Specially designed for metal block calorimeters. Heating element enclosed in a metal tube with two connecting leads which are insulated with heat resistant insulation. 12 V, 50 W.

Description

Apparatus is fitted on heavy channel base, at one end of which is an adjusting screw, at the opposite end is a micrometer screw reading to 0.01 mm for measuring the expansion. Supplied with one each of aluminium, brass and iron expansion rods but WITHOUT thermometer. Consisting of metal rod 500 mm in length and 4.5 mm dia. enclosed in a well - lagged, metal tube with three tubules for steam inlet, outlet and thermometer. The metal rod to be investigated is supported in the steam jacket by detachable rubber bungs situated at each end of the tube.

Description

A glass U-tube of 10 mm diameter the shorter limb of which has a stopcock near top and the longer limb can take a plastic tube. A scale is provided and can be attached to the shorter limb With red indicator oil but without 2000 ml tall form beaker which acts as a reservoir.

Description

Demonstrates the difference in thermal conductivity of two different materials. The kit consists of two identical blocks, one made of aluminum and other made of plastic. When an ice cube is placed on aluminum it turns into water in seconds, while on plastic block it melts slowly. The aluminum block has a larger heat capacity and a higher thermal conductivity while the plastic block has lower values of both parameters. With instructions.
