You heat up a 3.0 kg aluminum pot with 1.5 kg of water from 5 to 90 degrees C. the specific heat capacity of aluminum is 900J/kgK. ?
(a) how much energy did it take to heat the pot of water?
(b) the diameter of the cylindrical pot is 20cm and the height of the water is 4.8cm. How high (in mm) will the water column rise (assuming the diameter stays constant?) coefficient for volumetric expansion of water is 207e-6/deg. C.
(c) a small Air bubble is self contained trapped between the bottom of the aluminum pot and a glass stove top. One micro percent (1e-6%) of the energy that went into hitting the pot full of water (from part A) goes into the air bubble. As a result the bubble experiences of volume change of 3e-6m^3 with the pressure remain in constant. Assuming it acts like an ideal gas, find that pressure
