Across
- 4. is an electromechanical instrument used for detecting and indicating an electric current.
- 6. an expanded part of a glass tube such as that forming the reservoir of a thermometer.
- 8. is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction.It produces a temperature-dependent voltage as a result of the thermoelectric effect, and this voltage can be interpreted to measure temperature.
- 9. is the minimum possible thermal energy/temperature.
- 11. a place where something has become tighter or narrower; an obstruction in thermometer.
- 12. is an measure of average kinetic energy which each molecule of an object possesses.
- 13. it is one of the wires used in the thermocouple. It is a good conducter of heat.
Down
- 1. is the change in length per change in temperature.
- 2. is the difference between the maximum and minimum temperatures that the thermometer can read.
- 3. It freezes at -115 degrees Celsius and is suitable for low Artic temperatures but it has to be coloured to be seen easily.
- 5. it is used to read the temperature of the wall from the thermocouple.
- 7. is when a given change in temperature causes the same change in length.
- 10. is a special type of mercury thermometer used to measure the temperature of the human body.
