Why does conduction occur more easily in solids and liquids, than in gases?
blsea [12.9K]

Answer:

Because liquids and solids are denser than gasses.

Explanation:

Solids and liquids are denser than gasses making it easier for things like sound to conduct through them. Being dense contributes to a better conduction because the particles and such within the solid or liquid are closer together which allows for things like sound to travel at a much faster rate because they're so much easier to vibrate.

Cigarette smoke contains carbon monoxide. Explain how this
Olegator [25]

Answer: Carbon Monoxide is a very harmful and toxic gas which is formed from incomplete combustion of carbon.

Explanation: red blood cells contain haemoglobin ,which are responsible for carrying oxygen into our body system. So oxygen combines with haemagoblin to form oxyhaemogoblin in the red blood cells .

so if a person starts to intake cigarettes which contain high amounts of carbon monoxide ,it reduces oxyhaemogoblin formation because it binds very tightly to the haemogoblin .then carboxyhaemogoblin is formed and its permanent so causing reduction in aerobic respiration, and reduction in oxygen transport and causing damages to heart muscles.

Hope this helps if you need any more explanation feel free to comment in the comment section below !!!
