WebbThermometry And Thermal Expansion 1. Define heat (a) on conventional basis (b) on the basis of kinetic model. Ans. (a) On the conventional basis heat is the from of energy which causes in us sensation of warmth. (b)On the basis of kinetic model, heat is the sum total of kinetic and potential energies of all the molecules of a substance. 2. WebbThermometry is the process of measuring temperature. Temperature is basically a measure of the amount of kinetic energy, particles possess. Nowadays, there are many different types of thermometers, for example glass in tube, thermistor, thermocouple, radiation thermometer etc.
WebbThermal expansion occurs in solids, liquids and gases When temperature is increased (at constant pressure); Solids will tend to expand the least Gases expand the most Liquids fall in between the two Thermal Expansion in Terms of Particles EXTENSION Molecules do not expand, but the space in between them does Webb12 sep. 2024 · (a) In this common type of thermometer, the alcohol, containing a red dye, expands more rapidly than the glass encasing it. When the thermometer’s temperature increases, the liquid from the bulb is forced into the narrow tube, producing a large change in the length of the column for a small change in temperature.
WebbThermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions.. Temperature is a monotonic function of the … WebbIn physics, Thermal expansion can be defined as the change in the length, width, height, or volume of any material on changing the temperature. Thermal expansion is very evident …
