Does the size of the particles change as a substance changes state
Kazeer [188]
Ok, particle is not a very nice word, no real sense of size associated with it
it can be a group of molecules like a speck of sand
referring to the molecules themselves
or refering to the atoms that make up the molecule

now in terms of phase change,
if we consider a speck- a group of molecules- then solids will expand when heated, however this definition falls flat in terms of phase change

ok, how about molecules, as molecules undergo phase change, the molecules in relation to each other will move apart from one another. Solid- molecules are bonded, Liquids- molecules are close and flow around each other, Gas- molecules are a significant distance from one another. But the increase in size when you heat up a molecule, i would have to say yes. adding heat increases energy which increases molecular vibration which would probably  increase the overall average size to some unnoticeable degree.

now standalone atoms are just atoms, if you want to consider the electron cloud as size, then heating it up would negligibly cause the outer move outward. but it really depends on the scale of the question

If granite and marble were exposed in an area with a hot and humid climate, _____. the granite would weather more rapidly the ma
SOVA2 [1]

The correct answer is the marble would weather more rapidly.

The weathering of the rock can be defined as the procedure of the erosion of the rock by various agents. The marble is a metamorphic form of the limestone. The limestone is easily affected by the hot and the humid climates. The rain and the atmospheric carbon dioxide get mix together form mild acids, this acid react with the limestone and causes the chemical changes. As a result, the marble is subjected to erosion in hot and humid climate.
