To solve this problem it is necessary to apply Boyle's law in which it is specified that
Where,
and
are the initial pressure and volume values
and
are the final pressure volume values
The final pressure here is the atmosphere, then
Pressure at the water is given by,
Using Boyle equation we have,
Therefore the volume of the lungs at the surface is 5.9L
Answer:
-13.18°C
Explanation:
To develop the problem it is necessary to consider the concepts related to the thermal conduction rate.
Its definition is given by the function
Where,
Q = The amount of heat transferred
t = time
k = Thermal conductivity constant
A = Cross-sectional area
The difference in temperature between one side of the material and the other
d= thickness of the material
The problem says that there is a loss of heat twice that of the initial state, that is
Replacing,
Solvinf for ,
Therefore the temprature at the outside windows furface when the heat lost per second doubles is -13.18°C
