Step-by-step explanation:
Assuming the pressure is constant, we can use the combined gas law to solve for the new volume. The combined gas law is given by:
(P1 x V1)/T1 = (P2 x V2)/T2
where P1, V1, and T1 are the initial pressure, volume, and temperature, respectively, and P2, V2, and T2 are the final pressure, volume, and temperature, respectively.
We can rearrange this equation to solve for V2:
V2 = (P1 x V1 x T2)/(T1 x P2)
Substituting the given values, we get:
V2 = (1 atm x 0.95 L x 280 K)/(297 K x 1 atm)
V2 = 0.899 L
Therefore, the volume of the air bubble at 7°C is approximately 0.899 L.
