Accession Number: 2015.ph.707

Description:

The device consists of a copper cylinder, open at one end, with three metal prongs protruding from the closed end. The wires are made of steel, brass, and copper respectively. The cylinder is accompanied by piece of paper with handwritten notes. There is a paper tag attached to one of the prongs.

Primary Materials: Copper, steel, brass.

Markings:

Paper tag: “PHY 189”

Accompanying paper slip: “INGENHOUZ APPARATUS TO SHOW K ∝L2 WHERE L = LENGTH MELTED, WAX POUR BOILING WATER IN HERE, PUT APPARATUS IN LANTERN, THESE MUST BE AT TOP BEFORE WAX IS PUT ON RODS, DIP RODS IN WAX, THESE INDICATE LENGTH OF WAX MELTED, STEEL BRASS COPPER”

Dimensions (cm):

length = 13 cm, width = 13 cm, height = 33 cm.

Function:

The device was used to demonstrate the difference in thermal conductivity between materials.

Condition:

The device is in good condition. There is very minor oxidation of all metal surfaces.

Provenance:

The device was acquired from the University of Toronto physics department.
