- According to Pascal’s principle, for a certain fluid in a totally enclosed system, a change in pressure at a given point in the fluid is transferred to all points in the fluid, as well as to the enclosing walls.
- This is illustrated by the fact that the pressure inside an enclosed system is the same according to the relation [ pressure = force/area ]. Therefore, the change in pressure resulting from squeezing a ketchup bottle will be transferred equally to all parts of that bottle as well as its internal content.
- That’s how hydraulic machines, such as garbage trucks and hydraulic lifts function..
The metal increases the rate of reaction by providing an alternative pathway with a lower activation energy. this means that more reactant molecules will have energy equal to or greater than the activation energy, hence higher rate of reaction.
Answer and explanation;
Coal has aromatic hydrocarbons with high molar mass and has a high ratio of carbon to hydrogen. Burning coal produces more soot than burning other fossil fuels does because of it.
Fossil fuel mixtures of hydrocarbons that formed from the remains of plants or animals. Burning fossil fuels increases the amount of carbon dioxide in the atmosphere. This increase may affect temperatures, amounts of rain and sea levels worldwide. Some sulfur and nitrogen are in fossil fuels, and air contains nitrogen.
