Kenya has a pile of salt on the counter. she uses a pinch of it for a meal. which of the following physical properties of the salt changes? density shape solubility thermal conductivity

The following choices are all extensive properties, meaning they do not change with the amount of the substance. Although, 3 of the properties, namely, density, solubility and thermal conductivity are temperature-dependent. Since the problem did not mention of heating, let's assume Kenya just used it directly for her meal. Among the choices, I think shape would change. Once you place it in the meal, you can no longer pinpoint the salt because it's shape has been changed.

I’m guessing you’re more alert to yourself or your surroundings if you’re more concentrated
