Heat conduction rods, 4 x metals
Heat conduction rods, 4 x metalsSet of four rods in steel, brass, aluminum and copper in the same holder. Each rod is equipped with a liquid crystal indicator that turns green at approx. 40 °C and where the green temperature indicator moves up the rod in step with heat conduction in the metal. Max. working temperature approx. 100 °C; after cooling the experiment can be repeated.
Magdeburg Hemisphere, Black
Magdeburg Hemisphere, BlackThe Magdeburg hemispheres consist of two black hemispheres with a diameter of 10 cm, which can be tightly joined together and connected to a vacuum pump. When the air is pumped out, a vacuum is created between the hemispheres, and the external air pressure presses them together with great force.
