What makes a liquid in glass thermometer sensitive to a small changes in temperature?
As the temperature rises or falls the liquid in the reservoir (bulb) of the thermometer rises or falls ) the liquid expands (heats up) or contacts (cools off). The volume change is made visible in the capillary (tube) in the part of the thermometer with the scale. This is the only part of the thermometer into which the extra volume and expand.Increasing the volume of fluid or decreasing the diameter of the capillary makes the changes more apparent/

What should be the shape of an ideal thermometer and why?
An ideal thermometer should have a narrow, uniform tube with a bulb at one end to hold the temperature-sensitive liquid. This shape allows for easy reading of the temperature, as the liquid expands and contracts uniformly with temperature changes. The narrow tube also allows for quick response to changes in temperature.
What is the mechanism of a thermometer?
A thermometer typically consists of a temperature-sensitive element (such as mercury or a thermocouple) that expands or contracts with changes in temperature. This expansion or contraction is then converted into a temperature reading on a scale by mechanisms such as a bimetallic strip, a digital sensor, or a liquid crystal display.
What is liquid-in-glass thermometer?
A liquid-in-glass thermometer is a type of thermometer that consists of a glass tube filled with a liquid, typically mercury or alcohol, which expands or contracts with changes in temperature. The level of the liquid in the tube corresponds to the temperature, allowing for temperature measurement.
What is the liquid in a Galileo thermometer and how does it work?
The liquid in a Galileo thermometer is usually a clear alcohol or water-based solution. The thermometer works based on the principle of buoyancy, where the density of the liquid changes with temperature. As the temperature changes, the liquid expands or contracts, causing the glass spheres with different densities to rise or sink, indicating the temperature.
What is in a thermometer a t the bottom?
A thermometer typically contains a liquid, such as mercury or alcohol, at the bottom of the glass tube. This liquid expands and contracts as the temperature changes, allowing the thermometer to measure and display the temperature.
What makes a liquid-in-glass thermometer sensitive to a small change of temperature?
A liquid-in-glass thermometer is sensitive to small temperature changes because the liquid inside expands and contracts with changes in temperature. This expansion and contraction leads to a noticeable movement of the liquid in the narrow capillary tube, making it easier to detect even small temperature changes. Additionally, the glass tube and thinness of the liquid column increase the sensitivity of the thermometer.
Why does the liquid inside the tube of a thermometer goes up and down?
The liquid inside a thermometer rises and falls due to changes in temperature. When the temperature increases, the liquid expands and moves up the tube, indicating a higher temperature. Conversely, when the temperature decreases, the liquid contracts and moves down, reflecting a lower temperature. This expansion and contraction occur because the liquid, often mercury or colored alcohol, is sensitive to temperature changes.
What should be the shape of an ideal thermometer and why?
An ideal thermometer should have a narrow, uniform tube with a bulb at one end to hold the temperature-sensitive liquid. This shape allows for easy reading of the temperature, as the liquid expands and contracts uniformly with temperature changes. The narrow tube also allows for quick response to changes in temperature.
What is a laboratory thermometer?
A laboratory thermometer is used to check the temperature, or changes in temperature, of an object with precise accuracy.

Is there any thermometer which changes its colour due to temperature change?
Yes,its called as "liquid crystal thermometer".
How the liquid in a thermometer change so that it can be used to measure a temperature?
The liquid in a thermometer expands and contracts as the temperature changes. This causes the liquid to rise or fall in a narrow tube connected to the bulb of the thermometer. The markings on the tube indicate the temperature based on how high or low the liquid level is.
What is the definition of liquid filled glass thermometer?
A liquid-filled glass thermometer is a device used to measure temperature that consists of a glass tube filled with a temperature-sensitive liquid, typically mercury or alcohol. As the temperature changes, the liquid expands or contracts, causing it to rise or fall in the tube, which can be calibrated to show the corresponding temperature.
What is the liquid in a thermometer?
It can range from mercury to alcohol it depends on the manufacturer.
