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
Co2(s). Co2 Solid Solids have definite shape and definite volume. This is because the particles that build up a solid are crammed in a fixed, closely packed geometric arrangement.
Fluids (gases or liquids) do not have definite shape and occupies the shape of the containers. While gases assume the volume of the container, liquids occupy part of it.In aqueous solutions, the particles lose their shape and volume and occupies the shape of its solvent (water). The volume is also modified accordingly. CO2(s) has definite shape and definite volume. and the correct answer would be Co2 solid.
Answer:
The correct answer is - B. New Moon.
Explanation:
The change of moon disc from all black to all light to all dark again is called the lunar cycle. It takes almost 30 days (29.53059 to be precise). The time from all black to all light or all light to all black is almost 15 days. All black moon is termed as the new moon and all light is termed as the full moon.
As given that the full moon is shown happening on the eleventh of the month then what moon would be around 25 which is 14 days later that should be in waxing gibbous phase and almost new moon.
Thus, the correct answer is - B. new moon.
