LAB 14: IDEAL GAS LAW BASIC CONCEPTS TEXTBOOK: SECTIONS 15.2, YOUNG, 10TH EDITION DEFINITIONS Volume: The space taken up by an object, measured in cubic meters (m"). Pressure: For an enclosed gas, pressure is defined as the force exerted per area by the gas on the container walls, measured in Pascal (1 N/m) Temperature: A measure of the average kinetic energy of the molecules; measured in degrees Celsius. Scientists use Kelvins, an absolute scale; the conversion from degrees Celsius to Kelvins is: Tx = Tc + 273. Mole: the amount of a substance containing Avogadro's number NA of atoms or molecules. Avogadro's number NA = 6.022 x 1023 atoms or molecules. The mass of 1 mole of air at sea level is 28.94 g. IDEAL GAS LAWS BOYLE'S LAW For an ideal gas at constant temperature: PV = const., or, PV = PzV2 CHARLES' LAW For an ideal gas at constant pressure with temperature in Kelvins: V/T = const., or, V./T = V2/T2 GAY-LUSSAC'S LAW For an ideal gas at constant volume with temperature in Kelvins: P/T = const., or, P/T = P2/T2 COMBINED IDEAL GAS LAW For an ideal gas: PV = nRT, where n is the number of moles and R = 8.314J/mol. K PV = NkT, where N is the number of molecules and k = 1.381 x 10-23 1/K

Answer 1

* solution - volume of a sphere is given by. where, since = 4 TRR R=2.00 inches (radius of sphere). 1 inche = 2.54cm. therefore a 2 inche = 2.54x2.00 cm 12.00 inches = 5:08cm7 Now, Volume (V)= 4 * 3.14x5.08x5.08x5.08 V- 1646.57219072 V = 548.85739690066 cm3. 08 //=548.86 cm3 Ans 1/1
