Joule's Mechanical Heat Experiment Apparatus Manufacturer,Supplier and Exporter in India
Product Code : ILS-H-10932
Indian Lab Suppliers supplies the Joule's Mechanical Heat Experiment Apparatus (Product ID: 10932) as part of its heat and thermal physics range. This apparatus shows that mechanical work turned into heat by friction warms water, the idea behind the mechanical equivalent of heat.
Quick Answer
A cast aluminium cylinder turns freely on a cast metal pedestal, and vanes on its axle churn water in a copper vessel against fixed vanes. The vessel sits in a felt-lined wooden box that slides on a wooden base and has a thermometer clamp. Two pulleys on an aluminium sliding bracket, with two sets of slotted weights and cord, are used to measure the work done. The water temperature rises noticeably after two to three minutes of turning; comparing work done with heat gained gives about 4.2 J per calorie. The thermometer is not included.
