Question

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

Answer 1

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.
