Let's assume the initial volume of air in the tube is V1 = 15 cm^3 and the final volume of air in the tube is V2 = 7 cm^3.
The percentage decrease in volume can be calculated using the formula:
Percentage decrease = ((V1 - V2) / V1) * 100
Substitute the values:
Percentage decrease = ((15 - 7) / 15) * 100
Percentage decrease = (8 / 15) * 100
Percentage decrease = 53.33%
Therefore, the percentage decrease in the volume of air in the tube when steel wool in a test tube containing water was placed in a trough of water after days volume decreased from 15 cm to 7 cm is 53.33%.
