To solve this problem we will calculate the total volume of inhaled and exhaled water. From the ideal gas equation we will find the total number of moles of water.
An athlete at high performance inhales 4.0L of air at 1atm and 298K.
The inhaled and exhaled air contain 0.5% and 6.2% by volume of water, respectively.
During inhalation, volume of water taken is


During exhalation, volume of water expelled is


During 40 breathes, total volume of water taken is

During 40 breathes, total volume of water expelled out is

Therefore resultant volume of water expelled out from the lung is

From the body through the lung we have that

Here,
P = Pressure
R= Gas ideal constant
T= Temperature
V = Volume
Replacing,


Therefore the moles of water per minute are expelled from the body through the lungs is 0.373mol/min
Answer:
False
Explanation:
Circuit and packet switching refers to systems through which information or data is transmitted, only that great features in circuit switching are a dedicated channel
The <u>packet switching</u> data or information that is transmitted is previously assembled into packets. Each of the packages is transmitted individually and will be able to follow different routes to reach the destination. As soon as they do, those packages are re-assembled.
Packet switching is more efficient than circuit switching and is also more robust for data that can be sent with transmission delay, that is, it is not real-time, such as on a web page, email, files.
<u>Circuit switching</u> is a type of communication which is established or created through a dedicated channel that is known as a circuit, the duration of a session. As soon as that session is finished (such as a telephone call), the channel will be released and therefore can be used by another pair of users.
