For a human to smell a substance, The substance must be volatile, and molecules of it must be airborne and drift near the nose.
The substance must come in contact with an olfactory nerve-ending in the nose.
The olfactory nerve must react, by excitation, to the molecule, sending an electrical impulse to the brain.
The brain must receive and process olfactory (smell) nerve signals.

Which shows the temperatures of three substances in order from greatest to least?
Substance A: 100°C, Substance B: 98°C, Substance C: 90°C
Substance A has a higher heat capacity than does substance B and substance B has a higher heat capacity than does substance C. If you add the same amount of heat to all three which order shows the pro?
The order in which the substances will exhibit the highest increase in temperature is C, B, A. This is because substance C has the lowest heat capacity, so it will increase in temperature the most with the same amount of heat added. Substance A, with the highest heat capacity, will increase the least.
How do you arrange substances in increasing order if you know their density and which substance sinks or floats in various liquids?
Arrange the substances based on their density from lowest to highest. The substance with the lowest density will float on top of liquids with higher densities, while the substance with the highest density will sink to the bottom. Therefore, the substance that floats in the most liquids should be placed at the top of the list, and the substance that sinks in the most liquids should be at the bottom.
What 2 conditions that density has to meet in order for it to be used to identify a mystery substance?
Density must be a characteristic property of the substance, meaning it is unique to that substance and doesn't change with the amount or shape of the sample. Additionally, the density value of the substance must be compared to known values to determine a match, so accurate measurement and comparison methods are essential.
When a person develops a tolerance to a substance he or she no longer needs an increasing amount of the substance?
When a person develops a tolerance to a substance, their body becomes less responsive to its effects over time. As a result, they often need to take higher doses of the substance in order to achieve the same effects as before. This can lead to increased risk of dependence and potential overdose.

Why does sodium chloride have no smell?
when you are smelling something tiny particles of the substance have become gaseous and have entered your nose to be detected. In order for this to happen the intermolecular forces holding the molecules of that substance together must be weak. This makes the substance volatile. Molecular compounds fit this since they have very weak forces of attraction between their molecules. Ionic compounds on the other hand have comparatively very strong intermolecular forces that hold them together thus not allowing them to escape in gaseous form to be smelled.
