Hope's
Apparatus
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.
No. SF234-HA. Only $9.95 |

Density
Ball
For demonstrating the effect of temperature on the density of a liquid.
Consist of a copper ball (75mm diameter) properly loaded so that its
density is less than that of water and it floats. When the water is
heated, its density reduces and the ball sinks.
No. SF234-BA. Only $12.50 |

Air Thermometer Bulb
- top
For the qualitative study of expansion of liquids, the principles of
thermometry and the rise and fall of a liquid column due to expansion or
contraction of air in a bulb. Consist of a borosilicate glass bulb
50mm in diameter with 30cm long stem.
No. SF234-GA Only $8.95
Liquid Expansion Bulb
- bottom
For demonstrating and determining the coefficient of volume expansion of
liquids when heated. Consist of a borosilicate glass bulb to hold
10ml of a liquid in a capillary stem with a funnel at the top. The
capillary stem is graded to 0.5ml, subdivided every 0.01m.
No. SF234-GE. Only $10.95 |
