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?

a. Density
b. Shape
c. Solubility
d. Thermal conductivity

Answer 1

thoughts?

eliminate a) density (the mass/volume ratio is the same regardless of how much salt you have) and d) as this is a chemical property.

between b+c, which one actually changes when you go from a pile to a pinch?
