Hi I am working on the group work I need help with and a little explanation...
To whom it may concern, I need help with this question: Question: A scuba diver at 10 m below the surface of a lake, where the temperature is 5 degrees C, releases an air bubble with a volume of 16 cm^3. The bubble rises to the surface, where the temperature is 22 degrees C. What is the volume of the bubble (in cubic centimeters) just before it reaches the surface? (The density of water is 1000 kg/m^3 and air pressure...
need help solving this problem. show work so i can understand please. 6. At 25°C, a steel rod is 2 cm in diameter. It is to fit a hollow steel ring of diameter 1.995 cm. What temperature should the ring be heated to if the rod is to just fit in it? Alternatively, can the rod be subjected to some temperature change to get the same effect? Take the coefficient of linear expansion of steel=1.2 X 10-5/°Celsius
