Investigating Energy Transfer
Catalogue No: 1060825
Study heat and light with the simplest of materials – a black can, a silver or white can and a connecting copper bar. Measure the temperature inside dark and shiny bright cans to determine the different ways light and heat are absorbed and radiated. Fill both cans with water – one with hot, one with cold and connect them with the included energy transfer bar. Observe how the temperature of the water changes.

J Tube, Screw Fitting
Catalogue No. 4012300
Glass J-tube formed from 1mm bore thick walled capillary tube, with a brass screw and collar at the end of the longer limb. Used for sampling small quantities of gas held over water (e.g., in photosynthesis or respiration experiments). A bubble of gas is introduced into the short limb. This is then lowered into reagent solution and the bubble moved back and forth so that reagent diffuses through the end water seal. The change in length of the bubble indicates the amount of gas taken up by the reagent. Use potassium hydroxide for CO2 or alkaline pyrogallol for O2. Dimension: long limb – 250mm and short limb – 100mm.
