WEEK 4LESSON 2 WorksheetThe apparatus shown below may be used to investigate how the volume of a fixed mass of gas atconstant temperature varies when the pressure is changed. Air is trapped in a uniform glass tubewhich has a scale behind it calibrated in cm³. As the pressure in the oil chamber is increasedusing the pump, oil is forced into the glass tube, decreasing the volume of the air. The pressure,in kPa, is indicated by a gauge fitted to the oil chamber.Volume/cm³ 605550454035302520151010-Apparatus to investigate relationship between volume and pressure of a fixed mass of gasat constant temperature50 7530-The graph below was plotted from data gathered using the previous apparatus shown.40-50-10015020023027030060cm-102030-Glass tubeDry air100 125125 150Pressure gauge-Connection for pump32Oil175 200 225 250 275 300 325 350Pressure/kPaIt is suggested that if the temperature is constant, the pressure, P, of a fixed mass of gas is1inversely proportional to the volume, V, that is = kx P where k is a constant.To test whether the relationship applies in this case, read off values of V from the graph tocomplete the table below.

A bubble of air is rising from the sea floor, from a depth of about 500 m. At this depth the pressure is 5.1*106 Pa (about 50.3 atm) and is at a temperature of about 7.0° C. It rises to the surface with the atmosphere, at a temperature of 20° C. If the bubble is observed to have a volume of 4 cm³ at the surface, what was its volume at the sea floor? Assume the number of moles of gas in the bubble is constant. B.

We know from Newton's Law of Cooling that the rate at which an object warms up is proportional to the difference between the ambient temperature of the room and the temperature of the object. The differential equation corresponding to this situation is given by y' = k(M – y) where k is a positive constant. The solution to this equation is given by y = M + (yo – M)e-kt , where yo is the initial temperature of the object. Suppose your Thanksgiving turkey is kept at a temperature of 40 degrees Fahrenheit until it is put into a 350 degree Fahrenheit oven. It takes 2 hours for the turkey to warm up to a safe eating temperature of 165 degrees Fahrenheit. Find the values of yo, M, and k, for this situation, rounding your answers to 3 decimal places. Yo= M = k= Regardless of your answers above, suppose the k value in this situation is k = 0.3. Find the initial rate of increase of the turkey's temperature as soon as it is placed in the oven. Round to 3 decimal places. degrees per hour.
