Gas thermometers are more sensitive than liquid thermometers because gases

Gas thermometers are more sensitive than liquid thermometers because gases; option [B] have higher coefficient of expansion. The coefficient of expansion determines how much a substance expands or contracts with a change in temperature. Gases typically have higher coefficients of expansion compared to liquids, meaning they expand more for the same temperature change. This increased expansion results in larger changes in volume, which can be detected more easily, making gas thermometers more sensitive. Additionally, gases have the advantage of being compressible, allowing them to expand or contract more freely in response to temperature variations. This property enhances their sensitivity further. Liquid thermometers, while useful in many applications, often exhibit less sensitivity because liquids generally have lower coefficients of expansion than gases. Moreover, gases tend to have simpler and more predictable behavior over a wider range of temperatures compared to liquids, contributing to the higher sensitivity of gas thermometers. These characteristics make gas thermometers valuable tools in scientific research, industrial processes, and everyday temperature measurements.
