Question

Tommy wants to train for a half-marathon. It constantly rained so he trained in an indoor facility. Since he trained in July, he was happy that the temperature in the facility was kept at 70◦F. On the day of the race, the weather cleared up, but the temperature sky-rocketed to 100◦F that day, and as he started the race, he found his normal breaths did not seem to be replenishing oxygen to you as much as Tommy used to during training, and that he needed to inhale in more air when he breathed. Tommy was curious about how much more volume of air is needed at this temperature to get the same number of oxygen molecules into your lungs compared with the volume of air you were used to inhaling inside the indoor training facility.

Answer 1

In this question we will apply following concepts->

1.)convert the temperature Fahrenheit scale to Kelvin scale

2.)Use ideal gas equation

3.) Mole concept

Hence the extra volume needed is 78.94% of initial volume of toal inhaled air .
