Bubbles can form at the bottom of a river due to gases, such as methane or carbon dioxide, being released from decomposing organic matter in the sediment. These gases can get trapped under the water and eventually rise to the surface as bubbles.

When boiling water why do the bubbles come from the bottom?

I am just in Science 1 on FlVS. But if I remember right it is conduction. Conduction is where the moluicules inside move around faster and faster till the cooler part is warm. Now lets use a pot. The pot would start of cool unlike the stove. And it will as I pointed out up there make the pot warm to which will make the water warm and which it starts to boil.I hoped that helped,Logan Church


Why large bubbles form when water boils what are the bubbles made of?

When water boils, the bubbles are made of water vapor. Water is changing from the liquid phase to the gas phase, but it doesn't change all at once, so you get bubbles of gas inside the liquid. The phase change will happen first at the location where heating is taking place, so if you have a pot on a stove, the bubbles will form at the bottom of the pot, and then rise to the top.


What kind of rock is made from the materials at the bottom of rivers?

Depends on the river and where it is. Generally speaking, the river bottom will contain silt, clay, sand, gravels, even possibly boulders.


What temp do small bubbles start to show when boiling water g water?

Small bubbles start to form at around 160°F (70°C) in water as it begins to heat up and reach its boiling point of 212°F (100°C). These bubbles form at the bottom of the pot and rise to the surface as the water nears the boiling point.


Do soap bubbles last longer in warm or cold air?

Soap bubbles typically last longer in cool or cold air compared to warm air. This is because cooler air is denser and can help slow down the evaporation rate of the water in the bubble mixture, allowing the bubble to stay intact for a longer period of time.
