Where a thermometer should be kept in determining melting point of ice?
A thermometer should be immersed in the ice water mixture in order to accurately determine the melting point of ice. This ensures that the thermometer is in direct contact with the substance being measured and will provide a precise reading of when the ice starts to melt.
What are the fixed reference points on the celsius thermometer?
If you have 2 then you are right. The freezing point of water and the boiling point of water are the 2 fixed points.
Some laboratory thermometer use alcohol instead of mercury what are the advantages and disadvantges of using alcohol in thermometer?
Advantages of using alcohol in a thermometer include being less toxic than mercury, having a lower freezing point, and a wider temperature range. However, disadvantages include having a lower boiling point than mercury, being more flammable, and having a lower density which can affect accuracy.
What is the temperature taken as lower fixed point in Celsius scale?
The two main fixed points in the Celsius scale are: Zero degrees the freezing point of water and 100 degrees its boiling point. Any temperature below freezing are minus values, the lowest being -273 degrees absolute zero the point where everything stops.

What is the lower fixed point and upper fixed point of clinical thermometer?
The lower fixed point of a clinical thermometer is the temperature of the ice point (0°C) and the upper fixed point is the temperature of the steam point (100°C at standard atmospheric pressure). These fixed points are used to calibrate the thermometer for accurate temperature measurements.
How do you determine the lower fixed point of thermometer?
The lower fixed point of a thermometer is typically determined by immersing the thermometer in a mixture of ice and water. This point is known as the ice point, as it represents the temperature at which ice and water coexist in equilibrium under normal atmospheric pressure.
What is the upper fixed point and the lower fixed point in a clinical thermometers?
The upper fixed point in a clinical thermometer is typically the temperature of a healthy human body (e.g., 37 degrees Celsius). The lower fixed point is usually the temperature of melting ice (e.g., 0 degrees Celsius). These fixed points help calibrate the thermometer for accurate temperature measurements.
What determines the upper and lower fixed points of a thermometer?
Upper fixed point is the temperature of pure water boiling at normal atmospheric pressure.Lower fixed point is the temperature of a mixture of pure ice and pure water at normal atmospheric pressure. Each thermometer has a scale containing an upper and lower fixed points depending on the use of this thermometer for specific measurements.
What is the upper and lower fixed point of digital thermometer?
The upper fixed point of a digital thermometer is typically set at the boiling point of water, which is 100 degrees Celsius or 212 degrees Fahrenheit. The lower fixed point is usually set at the freezing point of water, which is 0 degrees Celsius or 32 degrees Fahrenheit. These fixed points provide known reference temperatures for calibration and accuracy checks.
What is the upper fixed point in the thermometer?
The upper fixed point on a thermometer is the temperature set at 100 degrees Celsius, which corresponds to the boiling point of water at standard atmospheric pressure. This fixed point is used as a reference point for calibrating the thermometer.
What is the effect of mineral impurities of the upper and lower fixed point of a mercury-in-glass thermometer?
Mineral impurities in the upper fixed point of a mercury-in-glass thermometer can lead to an increase in the boiling point of the liquid, affecting the accuracy of high temperature measurements. Impurities in the lower fixed point can similarly impact the freezing point, affecting the accuracy of low temperature readings. Regular calibration and cleaning can help mitigate these effects.
What do you mean by upper fixed point of thermometer?
The upper fixed point of a thermometer is the temperature at which a reference material, such as distilled water or mercury, reaches a stable temperature under specific conditions. This point is used to calibrate the thermometer and ensure accurate temperature measurements.
What is lower fixed point?
upper fixed point is a temperature of stem from water boiling and standards atmospheric pressure lower fixed point is the temperature of pure melting ice.

What is the lower fixed point in celsius scale?
The lower fixed point in the Celsius scale is 0 degrees Celsius. This point is defined as the freezing point of water at sea level under standard atmospheric pressure.
