Answer:
Radius of the bubble reaches the surface of the water = 4.68 cm
Explanation:
We know Ideal gas equation PV = nRT
Since amount of gas and temperature remains constant
so p₁v₁ = p₂v₂
Volume of Spherical bubble with a radius of 3.0 cm
⇒ v₁=
⇒ v₁ = x 3.14 x
Pressure at the depth p₁ = 4 atm
Volume of bubble when it reaches the surface of water =
Pressure p₂ = 1 atm
p₁v₁ = p₂v₂
⇒ 4 x x 3.14 x = 1 x
⇒ r = 4.68 cm
Answer:
5m3
Explanation:
becuase density= mass/volume
rearrange to make = volume=mass/density
15/3= 5
Answer: gasoline, water, sea water, chloroform and mercury so B
Explanation:
A value with zero uncertainty and an infinite number of significant figures is called an exact number.
A value that is known with confidence is called an exact number. In other terms, an exact integer has an infinite number of significant digits and zero uncertainty. It is impossible to simplify or reduce an exact number. A value with zero uncertainty and an infinite number of significant figures is called an exact number.
