Pumice stone must consist of 65-85% of trapped air to float in fresh water.
Which rock will float in water?
- Rocks sink when they are submerged in water due to their weight. The only rock that floats in water, on the other hand, is pumice. Due to its low density, pumice floats in water unlike other types of rock.
- When a volcano erupts and the lava immediately contacts the ocean, pumice rock is created. The water swiftly cools the lava, which then solidifies as pumice with lots of trapped air bubbles.
- It is light enough to float thanks to these air pockets. Pumice can float on water for years before becoming saturated and eventually sinking because it has a porosity of 64–85 percent by volume.

Goa's climate is tropical, hot all year round, with a long and sunny season, which runs roughly from mid-October to mid-May, and a rainy season due to the south-west monsoon, more or less from late May to early or mid-October, and characterized by stuffy weather, cloud cover and frequent rains, which occur almost daily .
The coconut seed is especially well adapted to increasing its range by the method of ocean dispersal. The seed floats when its outer layers dry out. The buoyant coconuts drift on ocean currents and end up on tropical beaches where they germinate and take root.
Coconut tree grows only in the tropical climate. This plant live on the sandy soil, requires a lot of sunlight and regular rainfalls. Coconut tree does not tolerate low temperatures and low percent of humidity.
so goa is one place which is suitable for growing coconut.
Hope you've understood ☺️
Hail. I'm sure that the answer you're looking for is hail. As the Updrafts force the water molecules up, they began to freeze, in which case they become heavy and start to fall, only to be carried up by another updraft, in which case it freezes again, while adding more water molecules. This process repeats until the hail is heavy enough to finally fall to the ground and escape the updrafts. So yes, the answer is hail, I hope this helped!
The two processes are coupled throughout the mitochondrial inner membrane that together make up oxidative phosphorylation are: Electronic transport chain and ATP synthase.
NADH and FADH2 formed during glycolysis; fatty acid and amino acid breakdown and the citric acid cycle contain high-energy electrons.
Oxidative phosphorylation is the process by which these molecules are oxidized by transferring their electrons to O2 and the resulting energy is used in the form of ATP synthesis.
This metabolic process is formed by a set of complex enzymes, located in the inner membrane of the mitochondria, which catalyze various oxidation-reduction reactions.
Oxidative phosphorylation includes two coupled mechanisms:
- Electron transport chain that the set of enzymatic complexes embedded in the mitochondrial membrane that oxidize NADH and FADH2 generating a proton gradient.
- ATP synthase that harnesses the energy of the proton gradient to produce ATP.
Both the electron transport chain and ATP synthase are embedded in the membrane, and energy is transferred from the electron transport chain to ATP synthase by the movement of protons through the membrane, in a process called chemiosmosis.
Therefore, we can conclude that oxidative phosphorylation works with two types of reactions that are coupled, the electronic transport chain that releases energy, while the other ATP synthase uses that energy to carry out its reactions.
