An air bubble at the bottom of a lake 25 m deep has volume 2.0 $c m^{3}$ . The temperature is $4^{\circ}$ C at the bottom and $1 0^{\circ}$ C at the top. Find its volume at the surface in $c m^{3}$ (two decimals). Use 10.3 m of water per atmosphere.

Answer:

7.00

Solution:

Bottom pressure = $1 + \frac{25}{10.3} = 3.427$ atm.

$V = 2.0 \times 3.427 \times \frac{283.15}{277.15} = 7.00$ $c m^{3}$ .
