Question: An athlete has a large lung capacity 7 0 L Assuming
An athlete has a large lung capacity, 7.0 L. Assuming air to be an ideal gas, how many molecules of air are in the athlete’s lungs when the air temperature in the lungs is 37 oC under normal atmospheric pressure?
Answer to relevant QuestionsIs there a temperature that has the same numerical value on the Kelvin and the Fahrenheit scales? Justify your answer. Convert the following to Fahrenheit readings: (a) 120 oC (b) 12 oC and (c) - 5 oC A steel beam 10 m long is installed in a structure at 20 oC. What is the beam’s change in length when the temperature reaches (a) – 25 oC and (b) 45 oC? A pie plate is filled up to the brim with pumpkin pie filling. The pie plate is made of Pyrex and its expansion can be neglected. It is a cylinder with an inside depth of 2.10 cm and an inside diameter of 30.0 cm. It is ...Table 10.1 states that the (experimental) coefficient of volume expansion for air (and most other ideal gases at 1 atm and 20 °C) is 3.5 x 10-3/oC. Use the definition of the volume expansion coefficient to show that this ...
