how work the hopes apparatus in detail
Answers
Hope's apparatus is a glass cylinder encircled with a trough half-way up to contain a freezing mixture. Holes in the cylinder at the top and the bottom allow thermometers to be inserted into the water to sample its temperature.
Hope’s Apparatus – Physics Equipments
Hope devised a simple arrangement, known as Hope’s apparatus.
Used to demonstrate the anomalous behavior of water.
It is a common experiment that when a liquid is heated, it expands, irrespective of the temperature range.
Comprising a cylindrical vessel, surrounded by an annular trough,
In which is to be placed a mixture of ice and salt.
The respective temperature of the water at the top and bottom of inner cylindrical vessel are measured over a period as the water cools.
Supplied without thermometer.
To show that water has a maximum density at 4 degrees Celsius.
Consists of a sheet metal cylinder with two tubes in the upper and lower regions for inserting thermometers through rubber stoppers.
Mounted on a base and encircled midway by an outer trough for holding a mixture of ice and salt.
Temperature of the water is measured at the top and bottom of the inner cylindrical vessel over a period as the water-cools.
Thermometer not included.
