Large wall mount thermometer with large numbers for indoor and outdoor use. Double scale (Celsius and Fahrenheit), perfect for schools, classrooms and educational activities.
It is 15” tall and 2.5 inches wide. It can hang to a small nail.
For teaching or experimenting the basic concept of generating electricity electrochemically. Voltic cell consists of a chemically inert plastic jar with plastic cap fitted with ZINC and COPPER plates and external terminals. 4" Diameter x 6" Height. Includes general instructions.
The Electric Calorimeter consists of an inner aluminum vessel 75 x 50 mm, Height x Diameter, and an outer aluminum vessel 100 x 75 mm, Height x Diameter, with a bakelite cover with two terminals, which are cross-drilled at their lower ends and are fitted with a heating coil, the upper ends are fitted with standard sockets for electrical connections. The bakelite cover has holes for thermometer and a stirrer. Supplied complete with stirrer but without thermometer.
Used to measure the specific heat capacity of liquids by electric method.
This product does not come with use instructions.
Ball and ring are used to demonstrate the thermal expansion and contraction of metals when heated and cooled.
When the ball is cold it can easily go through the ring. When you heat it up, it will expand (become larger) and does not go through the ring.
Ball and ring is a classic experiment showing the expansion of materials when they expand.
Expansion of materials by heat is one of the important factors engineers consider in making their designs of buildings, bridges and machinery.

This Calorimeter Set is designed for determining specific heat, heat of
fusion and heat of vaporization. The set consists of two polished spun
aluminum vessels, i.e. an inner calorimeter, 80 x 65 mm (height x diameter) and
an outer calorimeter, 140 x 100 mm (height x diameter).
