- If a mercury thermometer is immersed in hot liquid, the mercury level goes down at first and then goes up. Explain why this happens.A spherical air bubble originating from a scuba diver at a depth of 18.0 m has a diameter of 1.0 cm. What will the bubble's diameter be when it reaches the surface? (Assume constant temperature.)0•19 A 1.28-m-long vertical glass tube is half filled with a liquid at 20°C. How much will the height of the liquid column change when the tube is heated to 30°C? Take aglass = 1.0 x 10-5/K and Bliquid = 4.0 × 10-$/K. The answer IS O.13 mm. Please explain in neat and clear detal how I can arrive to get this answee. Thina you!
- **41. ssm Two identical thermometers made of Pyrex glass contain, re- spectively, identical volumes of mercury and methyl alcohol. If the ex- pansion of the glass is taken into account, how many times greater is the distance between the degree marks on the methyl alcohol thermometer than the distance on the mercury thermometer?At the bottom of an old mercury-in-glass thermometer is a 54-mm³ reservoir filled with mercury. When the thermometer was placed under your tongue, the warmed mercury would expand into a very narrow cylindrical channel, called a capillary, whose radius was 1.7 x 10-² mm. Marks were placed along the capillary that indicated the temperature. Ignore the thermal expansion of the glass and determine how far (in mm) the mercury would expand into the capillary when the temperature changed by 1.0 C°. AL=At the bottom of an old mercury-in-glass thermometer is a 39-mm reservoir filled with mercury. When the thermometer was placed under your tongue, the warmed mercury would expand into a very narrow cylindrical channel, called a capillary, whose radius was 1.8 x 102 mm. Marks were placed along the capillary that indicated the temperature. Ignore the thermal expansion of the glass and determine how far (in mm) the mercury would expand into the capillary when the temperature changed by 1.0 C°. AL = the tolerance is +/-2%

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/K
