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 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 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.

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 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.
Why do you use pure ice in determining a lower fixed point of a thermometer?
Pure ice is used to determine a lower fixed point of a thermometer because it is a well-defined substance with a known melting point of 0°C under standard atmospheric pressure. This makes it a reliable reference point for calibrating and verifying the accuracy of a 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 are the fixed references points on the celsius thermometer?
0 to 100 i think
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.
How do you take the temperature of a tennis ball?
You can take the temperature of a tennis ball by using a digital thermometer or an infrared thermometer. Simply point the thermometer at the ball and press the measurement button to get a reading of the ball's temperature.
