What would be the major cause of error in the mercury-in-glass thermometer?
Step by step
Solved in 2 steps
- When an ordinary mercury thermometer is placed in hot water, its reading drops at first but quickly rises again. Explain why.The filament of an evacuated light bulb has a length 10 cm, diameter 0.2 mm and emissivity 0.2, calculate the temperature of the filament, if the power radiated by filament is 11.4 watt.Mercury thermometers cannot measure temperatures below -30◦C because at that temperature Hg becomes pasty. Could you indicate to what temperature Fahrenheit and Kelvin it corresponds?
- Under what conditions is the thermal resistance of the tube in a heat exchanger negligible?A copper calorimeter of 100 g mass containing 200g of water was used. The thermometer contained 0.8 cm3 of mercury and 3 g of glass. What error is introduced by neglecting the heat capacity of the thermometer?Suppose that a Celsius thermometer was created with alcohol (instead of mercury) as the liquid. a) Would the alcohol and mercury thermometers read exactly the same at every temperature being measured? Assuming that both thermometers are small in comparison with the objects whose temperatures are being measured. b)What does the answer in a) imply about measurements of temperature?
- The primary and secondary mirrors of a space telescope are assembled using zerodur spacers in an engineering laboratory in which the room temperature is 20 degrees C. In space the telescope will drop to -30 degrees C. If the distance between the mirrors is exactly 80 cm in the lab, how much would the length of the zerodur spacer change in space? The properties of the material zerodur can be found in the table. Coefficient of thermal expansion is 2x10^-8 K^-1 and specific heat is 3347.20 J/kg/KThe outer surface of a spacecraft in space has an emissivity of 0.8 and a solar absorptivity of 0.3. If solar radiation is incident on the spacecraft at a rate of 950 W/m?, determine the surface temperature of the spacecraft, when the radiation emitted equals the solar energy absorbed.If a copper calorimeter of 100g mass containing 200g of water was used. The thermometer contained 0.8 cm3 of mercury and 3 g of glass. what error is introduced by neglecting the heat capacity of the thermometer?
- Q.2/A thermocole cubical ice box of side 30 cm has a thickness of 5.0 cm. If 4.0 kg of ice is put in the box, estimate the amount of ice remaining after 6h. The outside temperature is 45C, and thermal conductivity of thermocole box is 0.01 Js'm k, knowing thatilatent heat of fusion is 335* 10 J/kg.Mercury thermometers cannot measure temperatures below -30◦C because at that temperature Hg becomes pasty. Could you indicate to what temperature Fahrenheit and Kelvin it corresponds? Text Digital PleaseExplain why it would not make sense to use a full-size glassthermometer to measure the temperature of a thimbleful of hot water.
