The ice and steam point on a mercury in glass thermometer are found to be 90.0°mm apart what temperature is recorded in degree Celsius, when the length of the mercury thread is 33.6mm above the ice point mark
To find the temperature recorded in degrees Celsius, we need to know the temperature difference per unit length on the thermometer.
First, we need to find the temperature difference per unit length (TDUL). We know that the ice and steam points are 90.0 mm apart, and we need to find the temperature difference between them in degrees Celsius (TD). Since TDUL is in degrees Celsius per millimeter (°C/mm), we divide TD by the length between the ice and steam points:
TDUL = TD / 90.0 mm
Next, we need to find the temperature difference between the point 33.6 mm above the ice point and the ice point (ΔT). We can multiply the TDUL by the length above the ice point to find ΔT:
ΔT = TDUL * 33.6 mm
Finally, we can find the temperature (T) recorded in degrees Celsius by adding ΔT to the temperature at the ice point:
T = ΔT + ice point temperature
Without knowing the TD value or the ice point temperature, we cannot calculate the exact temperature recorded.
