The answer should be fewer based on the question. The oxygen molecules in the air are spread more thinly and therefore you take in less oxygen molecules per breath. Hope this helps!

A sealed container at 25oC contains a gas at a pressure of 104 kPa. What is the pressure of the gas when it is heated to 225oC?
seropon [69]

Answer:

174 kPa

Explanation:

Given that,

Initial temperature, T₁ = 25° C = 25+273 = 298 K

Final temperature, T₂ = 225°C = 225 + 273 = 498 K

Initial pressure, P₁ = 104 kPa

We need to find the new pressure. The relation between the temperature and pressure is given by :

\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}

So,

P_2=\dfrac{P_1T_2}{T_1}\\\\P_2=\dfrac{104\times 498}{298}\\\\P_2=173.79\ kPa

or

P₂ = 174 kPa

So, the new pressure is 174 kPa.
