03. Excess of Pressure (Bubbles and Drops)
Mechanical Properties of Fluids

143111 Consider the following two statements $A$ and $B$, and identify the correct choice in the given answer:
A: The excess pressure inside a small liquid drop is more than that of a big drop
B: As the aeroplane moves fast on the runways, the pressure is more on the upper surface of its wings and less on the bottom surface of wings.

1 both A and B are true
2 $A$ is true but $B$ is false
3 A is false but $B$ is true
4 both A and B are false
Mechanical Properties of Fluids

143116 Which one of the following weather conditions indicates a sudden fall in barometer reading?

1 Stormy weather
2 Calm weather
3 Cold and dry weather
4 Hot and sunny weather
Mechanical Properties of Fluids

143072 Two drops of a liquid coalesce to form a single big drop. In this process

1 energy is released
2 energy is absorbed
3 energy remains unchanged
4 energy may increase or decrease depending on index of liquid
Mechanical Properties of Fluids

143074 A drop of oil is placed on the surface of water then it will spread as a thin layer because-

1 Surface tension tends to give the oil a spherical surface
2 Surface tension of water is greater than that of oil
3 Both oil and water have nearly equal surface tension
4 Oil is lighter than water
