JudyA constant volume thermometer measures temperature by keeping the volume of the gas inside the thermometer constant. As temperature changes, the pressure of the gas inside the thermometer also changes, which can be correlated to the temperature. This type of thermometer is commonly used in laboratories and for precision measurements.

Why constant gas thermometer is preferred over the constant volume thermometer?
Constant gas thermometers are preferred over constant volume thermometers because the gas thermometer can be easily adjusted to atmospheric pressure, providing accurate readings. Additionally, the gas thermometer can measure a wide range of temperatures, making it versatile for various applications. Constant volume thermometers are limited in the range of temperatures they can measure and are less commonly used for precision measurements.
What is constant in mercury- in- glass thermometer?
One constant in a mercury-in-glass thermometer is the volume of mercury in the bulb, which expands and contracts with temperature changes. Another constant is the linear expansion coefficient of the glass tube, which allows for an accurate measurement of temperature based on the change in volume of the mercury.
How does constant volume gas thermometer works?
A constant volume gas thermometer works by measuring the pressure of a fixed volume of gas at different temperatures. As the temperature increases, the gas molecules move faster, creating more collisions with the walls of the container, leading to an increase in pressure. By calibrating the pressure readings at different temperatures, the thermometer can accurately measure temperature changes.
What is a constant volume gas thermometer?
A constant volume gas thermometer is a device that measures temperature based on the expansion of gas in a fixed-volume chamber. As temperature increases, the gas expands and exerts pressure, which is used to determine the temperature. This type of thermometer is accurate and reliable for measuring temperature in various applications.
How is the gas thermometer made in physic?
A gas thermometer consists of a fixed volume of gas in a sealed container. The pressure of the gas is directly proportional to its temperature, so by measuring the pressure and knowing the volume of gas, we can determine the temperature. This relationship is described by the ideal gas law, PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature.
