A liquid thermometer is a liquid-in-glass thermometer that makes use of the expansion or contraction of a liquid to measure temperature. The most liquid used in thermometers are mercury and alcohol. The change in the rise in volume of the liquid used in the thermometer owing to the rise in the temperature is scaled on a calibrated scale to indicate temperature.
Advantages of using mercury as a thermometric substance over other liquids:
1. High Boiling Point: Mercury boils at a relatively high temperature of around 356°C. This characteristic makes it suitable for measuring high temperatures without evaporating.
2. Uniform Expansion: Mercury expands uniformly with temperature change, thus ensuring accurate readings.
3. Good Visibility: Mercury has a shiny metallic appearance, which is also easy to see, especially in the very narrow capillary tube of a thermometer.
4. Mercury is not volatile and hence non-volatile which makes it non-evaporate at room temperatures; this stability allows its longevity.
5. It possesses great thermal conductivity so gives rapid temperature variation reading
6. Non-reaction mercury. The nature is such that chemical reaction is slow or hard which makes sure the chemical interaction between substances is hard or slower due to inert.
Although these have several advantages, mercury thermometers are less commonly used today because of environmental and health concerns related to mercury toxicity.
Ideal gas temperature refers to the temperature at which the behavior of the gas is based on the ideal gas law. According to the ideal gas law, gas particles do not interact with one another except for in an elastic collision. Temperature, in an ideal gas, is proportional to the average kinetic enerRead more
Ideal gas temperature refers to the temperature at which the behavior of the gas is based on the ideal gas law. According to the ideal gas law, gas particles do not interact with one another except for in an elastic collision. Temperature, in an ideal gas, is proportional to the average kinetic energy of the molecules of the gas.
The nature of the gas does not depend on its ideal gas temperature. For an ideal gas, every gas is pretty much the same; the temperature is a measure of average kinetic energy of the particles. The ideal gas law (PV = nRT) considers that the gases are in the form of non-interacting particles. This assumption in itself is quite valid for many gases, if their nature were concerned when operating at high temperature and low pressure.
