A platinum resistance thermometer has resistances of 5.25 Ω and 9.75 Ω at 0⁰C and 100⁰C respectively. Find the temperature in Celsius when the resistance is 8.25 Ω. Answer should be in 1 decimal place
(a)
The ice and steam points on a thermometer correspond to Q and 80 mm respectively. A temperature of 60⁰C corresponds to 52 mm on the thermometer. Find the value of Q
(a)
A thermometer with an arbitrary scale Y registers -50⁰Y at the lower fixed point and +70⁰Y at the upper fixed point. Find the Celsius temperature corresponding to 30⁰Y. Answer should be in 1 decimal place
(a)
A constant volume gas thermometer indicates a pressure of 250 mmHg at the ice point and 750 mmHg at the steam point. What is the temperature when the thermometer
indicates a pressure of 450 mmHg?
(a)
The lower fixed and upper fixed point of a mercury - in – glass thermometer are marked Y and 180 mm respectively. On a particular day, the mercury meniscus rises to 45 mm. If the corresponding reading on a Celsius scale is 100C , Calculate the value of Y.
(a)
A thermometer with an arbitrary scale oS , of equal divisions registers – 30 oS at the ice point and +90 oS at the steam point. Calculate the Celsius temperature corresponding to 60 oS.
(a)
A Thermometer has its stem marked in mm instead of degree Celsius. The lower fixed point is 30mm and the upper fixed point is 180 mm. Calculate the temperature in degree Celsius when the thermometer reads 45 mm.
(a)
The ice and steam points on a thermometer are found to be 96mm apart. What temperature is recorded on a Celsius scale thermometer when the length of mercury thread is 33.6mm above the ice point mark?
(a)
A platinum resistance thermometer measures temperature on the assumption that the change I electrical resistance of platinum is proportional to the change in temperature. The resistance of the platinum wire at 00 C is 10.4 ohms and 10.71 ohms at 1000 C. Calculate the temperature when the resistance is 9.61 ohms.
Answer should be in 1 decimal place.
