Answer:

The value of Y is -10°.

Explanation:

For scale X, the freezing point is 40° and the boiling point is 120°.

The gap between the two endpoints for scale X = 120 - 40 = 80

For scale Y, the ice point and steam point are -30° and 130° correspondingly.

The difference between these two points for scale Y = 130 - (-30) = 160

Comparing both scales:

One unit in scale X is x

One unit in scale Y is y

Scale X consists of 80 divisions, while scale Y has 160

80x = 160y

x = 2y

50° on scale X equals 10x plus the freezing point of scale X

10 divisions in scale Y correspond to 20y

The reading on scale Y = the ice point of Y + 20y

= -30° + 20°

= -10°

To address this problem, Boyle's Law must be applied, which states that the initial and final pressures and volumes are related as follows: Where, P₀ and V₀ represent the initial pressure and volume, while P and V refer to the final pressure and volume. The endpoint pressure in this scenario is atmospheric pressure. Thus, using the given equation, we can find the volume the lungs would occupy at the surface.
