An exothermic chemical reaction is change in the chemicals that can never be undone, an exothermic solution is a combination of chemicals
Explanation:
Fossil fuels are important energy sources for our every day activities.
Formation of fossil fuels
Fossil fuels forms from the accumulation and burial of organisms in a basin of deposition. Instead of the organisms decaying, they preserve their carbon content. To be worthy of becoming fossil fuels, organisms must be buried in an environment where there is little to no oxygen to fast-track decomposition of the buried organic matter. Increase in temperature and pressure causes the organic matter to transform into fossil fuels.
How are they obtained
First, different fossil fuels have their extraction techniques because they occur in different physical state of matter.
For the solids e.g coal: exploration is carried out first and if a prospect is delineated, mining engineers design the best way to extract the coal from nature. Coal is usually found laid in sedimentary beds in nature. Top layers of sediments can be removed to extract the coal.
For fluids such as crude oil and natural gas, after a prospect is identified, a rig is usually constructed to extract the fluid and gas. The natural pressure allows for the fluids the rise within the drill used in extraction.
How are they used
Coal and gas are used to power electrical generating plants. They are used to heat steams which drives turbines and produce electricity.
Natural gas is used as a domestic fuel for cooking and so also coal.
When crude is processed a lot of product is obtained. Gasoline is used to power most internal combustion engines. Some chemicals useful for manufacturing plastics, drugs e.t.c are also derived from the processed crude.

Meteorologists classify tropical cyclones using a measurement of sustained winds within the low-pressure system. How do meteorologists define a "sustained wind"?
it is a 1-minute averaged measure of the hurricane's maximum winds.
If a given year has more named storms than the name-list has names, how are additional storms named?
they are assigned names using the Greek alphabet.
Answer:
Generalization
Explanation:
In classical conditioning, generalization refers to the ability of an organism to respond to a stimulus the same way it responds to a stimulus that is similar. For example, generalization is seen in Pavlov’s experiment with dogs, after the pairing of the meat powder with the tone of a bell. The dog which naturally salivates as an unconditioned response to the meat powder (unconditioned stimulus), also later produce similar response (conditioned response) when presented only with the sound of a bell (conditioned response). This is generalization in classical conditioning, as the dog responds in a similar way to meat powder and also to the tone of a bell.
