Ǥ ͳ ǯ law, and gas volume is the controlled Ǣ ʹ study Boyle’s law, and gas pressure is the controlled variable. Ǥ ͳ ǯ law, and gas pressure is the controlled Ǣ ʹ Boyle’s law, and gas temperature is the controlled variable. 2. ǯ ǡ the volume of gas at atmospheric pressure was: F. 32 mL. G. 64 mL. H. 100 mL. J. Cannot be determined from the given information 3. ʹǡ ǣ A. measure the pressure of the air in the glass Ǥ B. measure the temperature of air in the glass Ǥ C. transmit pressure from the reservoir to the gas in the glass tube. D. transmit air to the gas in the glass tube.
Experiment 2 The students investigated the change in the volume of a gas at room temperature (294 K) at different pressures using the apparatus shown in Figure 3. A glass tube contained a pure nitrogen gas sample (a), and its volume (in mL) was read from the scale. A column of oil (c) transmitted pressure from the reservoir (b), and the pressure value was read on the gauge (d). Table 1 summarizes the data.
