Question

QUESTION 9 Consider a gas with a volume of 15.0 mL at a temperature of 390 K. What is the temperature of the gas if the volume drops to 5.0 mL? QUESTION 10 Boyle's Law is helpful for understanding breathing, however it does not fully apply because as we breathe, air rushes into our lungs and out of our lungs. This means that during breathing the number of gas particles does not remain constant. For this problem, assume a person is holding their nose (keeping air from coming and going) and then attempts to expand their chest to breathe in. If normal lung capacity is 6.00L and increases to 6.50L while breathing in, what will the pressure in the expanded lungs be if normal pressure is 755 mmHg? (Pay attention to sig figs!) QUESTION 11 A volcano releases a 100.0 ml bubble of gas at 598K and 1.80 atm. What is the size of the gas when it reaches cooler air high in the atmosphere with a temperature of 348 K and a pressure of.800 atm?

Please use simple equations from one of these concepts:

1.) combined gas law

2.)Boyle & Charles

3.) Ideal Gas Law

Please clearly display the equation used to find the answer. Thank you.

Answer 1

9) Using Charles law, volume is directly proportional to temperature at constant pressure,

T_f = T_i*V_i/V_f

_{= 390K*15mL/5mL}

   = 1170 K answer
