What effect does observing a substance's physical properties have on the substance?
Answers
There is no effect. When you observe a substance's physical properties, you're not doing anything that would catalyze a chemical change. For example, you most often observe with your eyes, and/or, if safe, you waft the substance's smell to your nose. Neither of these observations will effect the substance's physical properties.
what ere the different types of petrol used in petrol pumps?what is the composition of each and what type of vehicle is each suitable for?is there a difference in the price?
Answers
Petrol is primarily characterised by its octane number which defines its ability to burn efficiently and produce more energy per unit. A low octane petrol particle blast inside the engine instead of burning from spark this is called knocking as it produces knocking sound in the engine, to counter this an anti-knocking agent is added to petrol. Earlier Lead was used as an anti-knocking agent but it is highly toxic ,also the researchers who experimented lead with petrol died unnatural death. In later stages when effects of lead toxicity started showing up lead was replaced by benzene compounds as anti-knocking agents this is know as Unleaded petrol. Benzene is carcinogenic and started showing its ill effects after few years especially in densely populated cities. Govts have reduced the concentration of benzene in petrol thereafter and emphasised on implementation of Euro iv standards.
How do higher temperatures influence a chemical change?
Answers
Basically, temperature changes the reaction, which means that it would be a chemical change since it changes the formation of bonds and reactions.
It determines how fast the chemical occurs. For example, the enzymes (speeds up the reaction ) works fast when you put a fish in a refrigerator. It takes a longer time for this fish to spoil due to the temperature..
