Answer : The temperature of the air in the tire is, 341 K
Explanation :
Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.
or,
where,
= initial pressure = 198 kPa
= final pressure = 225 kPa
= initial temperature =
= final temperature = ?
Now put all the given values in the above equation, we get:
Therefore, the temperature of the air in the tire is, 341 K
Answer: A. 1.60 liters
Explanation:
As can be seen from the balanced chemical equation, 2 moles of produce 1 mole of
.
According to Avogadro's law, every 1 mole of the gas occupies 22.4 liters at STP.
Thus moles of
occupies
at STP and produce 1 mole of
i.e. 22.4 L
44.8 L of will produce 22.4 L of
Thus of
will produce
