Record your data and answer the conclusion question Radius of the tube in cmcm (slide 3-to find the radius measure the diameter of the capibillary tube using the cm ruler and divide by 2)

Temperature of gas (c) read the actual temperature on the thermometer

Height of the column of gas (cm) record the height of the gas at the bottom of the stopper.

Temperature of gas (k) k=C +273

Volume of gas (cm3)
V=r2h=3.14 r= radius of tube h=height of gas in tube your answer should have 2 significant digits.)

Ratio V/T ( cm3/K)

DIvide the volume by the temperature in K.

Your answer should have 2 significant digits
