UTH-9 BROWNIAN MOTION OF MOLECULES
'Brownian motion' is defined as the random or zig zag
motion of the suspended molecules, this will
demonstrated under a microscope with a CCTV camera.
UTH-05 HEAT CAPACITY OF LIQUID
A metal cylinder,calorimeter with two holes for inserting
a heating element and a thermometer or temperature
sensor fill with liquid .
UTH-08 BOILING POINT OF LIQUID
Boiling-point elevation shows that a solution has a higher
boiling point than a pure solvent. This happens whenever a
non-volatile solute, such as a salt, is added to a pure solvent,
such as water. in this experiment a:
Measure the increase in the boiling point of water as a
function of the concentration of table salt,
Investigate the relationship between the increase in boiling
point and the number of pellets.
Determine the molar mass of the solute from the relationship
between the increase in boiling point and the concentration.
UTH-07 CONVERSION OF ELECTRICAL ENERGY TO
HEAT AND THERMAL ENERGY TO ELECTRICITY
The experiment explore how where electrical energy is
converted into thermal energy for use and the thermal
energy to electrical energy .
UTH-03 SOLAR RAY COLLECTION
Set of equipment including four test bodies with different surface
coating, heat insulators, and covers for experiments on the utilisation
of solar energy.
UTH-02 THERMAL EXPANSION IN LIQUIDS
UTH-04 HEAT CAPACITY OF METALS
A metal block,calorimeter with two holes for inserting a heating
element and a thermometer or temperature sensor.
UTH-06 SPECIFIC HEAT CAPACITY
Using this experiment setup to calculate the specific heat capacity
of metal, for confirming the energy conservation law.
UTH-01 HEAT EXPANSION IN SOLIDS
If solid bodies are heated up, they generally expand to a greater or
lesser degree. In this experiment,
hot water is allowed to flow through tube with rod made of brass, steel
and glass. The expansion in their length is measured using a dial
gauge. The linear expansion coefficients for the three materials are
then calculated from the change in their length.
UTH-01A THERMAL EXPANSION USING MICHELSON
This device includes a Michelson interferometer and an oven,
together with a sensor and mirrors etc. Displacement of the
specimen ends are measured in terms of the number of
interference fringes. Therefore, the linear expansion coefficient of
the testing material can be calculated accurately.

UTH-10 HEAT CONDUCTION
Conduction of heat involves heat being transferred from a hotter part of an
object to a colder area by means of the interaction between neighbouring
atoms or molecules, although the atoms themselves remain in place.
In a cylindrical metal bar with ends maintained at different temperatures, a
temperature gradient will emerge along the bar after a while.
The temperature decreases uniformly from the warm end to the cold end
and a constant flow of heat arises through the bar.
The way the situation changes from a dynamic state to a steady state is
observed by means of repeated measurements to determine the
temperatures at various measurement points.
The metal bars are electrically heated so that the flow of heat in the steady
state can be determined from the electrical power supplied.
UTH-11 HEAT CONDUCTION DEMONSTRATION
Four different metals with wax at its ends, by heating the
center can see how the heat conducts in different metals.
