In physics, heating is transfer of energy, from a hotter body to a colder one, other than by work or transfer of matter. It occurs spontaneously whenever a suitable physical pathway exists between the bodies.
CHEMICAL CLOCK & WATER CLOCK
This clock keeps accurate time using energy from a battery that you make. Simply add weird liquids such as soda, fruit juice, dilute ketch-up, salt water, etc. to the two containers, insert four metal electrodes, and connect with three wires.
HEAT AND THERMOMETER KIT
This kit is used in heating and cooling of water or any inflammable liquid, converting a liquid into a gas and other basic experiments related to heat.
MELTING POINT APPARATUS
It can be used in determining repeatable melting point of different compounds up to 400°C in 5 minutes by continuously adjustable with built-in variable transformer. Temperature resolution 0.1°C with low mass thermocouple and precision thermometer. Its housing is made of aluminum. It accepts up three capillaries. Samples are illuminated and clearly visible through the precision 6-power lens. Operatable at 220V AC.
