1. a mountain biker goes for a ride in the desert. the air temperature is 21°c at the start of the ride, but the temperature in the desert will reach a peak of 51°c. the tires on the bike hold 15.6 l of nitrogen gas at a starting pressure of 249 kpa. the tires will burst when the internal pressure (pb) reaches 269 kpa. answer the following questions and show your work. • how many moles of nitrogen gas are in each tire? • what will the tire pressure be at the peak temperature in the desert? • will the tires burst at the peak temperature? explain. • to what pressure should the tire pressure be reduced before starting the ride to avoid bursting of the tires in the desert heat? (assume no significant change in tire volume.)
