A bubble having a diameter of 27 cm is re- leased from a depth of 4.6 m from the bottom of a swimming pool. The temperature of the water at the surface is 18°C, whereas it is 17°C at the point of release. What will the diameter of the bubble be when it reaches the surface? The acceleration of gravity is 9.8 m/s² and the density of water is 1000 kg/m³. Answer in units of cm. Answer in units of cm.

The laboratory balances have a precision of 0.01g. If you are obtaining the mass of an approximately 5 gram sample, which of the following is a proper way to record this measurement in your laboratory notebook and on your report sheets.     4.92 g     4.92     4.925 g     5.00 g

Older railroad tracks in the U.S. are made of Part A 12-m-long pieces of steel. When the tracks are laid, gaps are left between the sections to prevent buckling when the steel thermally expands. If a track is laid at 16° C, how large should the gaps be if the track is not to buckle when the temperature is as high as 50° C? The coefficient of linear expansion of soft steel is 1.1 × 10-5 °C-1.

A bubble having a diameter of 62 cm is re- leased from a depth of 4.6 m from the bottom of a swimming pool. The temperature of the water at the surface is 21°C, whereas it is 15°C at the point of release. What will the diameter of the bubble be when it reaches the surface? The acceleration of gravity is 9.8 m/s² and the density of water is 1000 kg/m³. Answer in units of cm.

A Pyrex flask in a refrigerator at –7°C is filled to the top and holds exactly 1000 cm³ of ethyl alcohol. If the refrigerator fails, how much alcohol spills by the time the temperature reaches 28°C? The coefficient of volume expansion of ethyl alcohol is 0.00112 (°C)-!. Ignore the expansion of the flask. Answer in units of cm³.

A hollow aluminum cylinder 19.5 om deep has an internal capacity of 2.000 L at 21.0°C. It is completely filled with turpentine at 21.0°C. The turpentine and the aluminum cylinder are the slowly warmed together to 79.0°C. (The average linear expansion coefficient for aluminum is 24 x 10-c, and the average volume expansion coefficient for turpentine is 9.0 103) (a) How much turpentine overflows? cm³ (b) What is the volume of turpentine remaining in the cylinder at 79 0°C? (Give your answer to at least four significant figures) (c) If the combination with this amount of turpentine is then cooled back to 21.0°C, how far below the cylinder's rim does the turpentine's surface recede? om
