Heat Experiment Apparatus

Question 1

Thermocouple thermistor

Answer 1

Useful for measuring temperature of a small space.

Question 2

Thermistor + associated circuity

Answer 2

Can be used to measure temperature (apart from measuring resistance). *As with the thermocouple. State that the resistance of the thermistor is first calibrated against temperature in a preliminary experiment.

Question 3

Copper calorimeter

Answer 3

Copper container with insulation and stirrer. Usually used to heat capacity experiments. Need to take into account the mass of the container and its heat capacity.

Question 4

Constant temperature bath/enclosure

Answer 4

Large tank of fluid with relatively constant temperature inside.

Question 5

Heater (constant power)

Answer 5

Can supply heat energy at a constant rate to a fluid.
