Hi! Now, I was thinking about water. And it seems like a silly question, but is water a solid?
No, right? Well think about it, water is solid at the atomic level...Still no? Let's say we have a giant as big as the Sun, apples are a liquid to a giant! Get it?
Is it about perspective and am I right or wrong?
I would love to hear your thoughts!

At the atomic level, all matter (solids, liquids, and gases) is made up of moving atoms. However, the phase of a substance (whether it is a solid, liquid, or gas) is defined based on how much the atoms are moving (and equivalently how far apart they are from each other).
For example, the atoms which make up a solid barely move. They vibrate, but they are always very close to each other. On the other hand, the atoms which make up a gas are constantly moving all over the place. They bounce off of all surfaces, and are very far away from each other. The atoms in a liquid move more than those in a solid, but less than those in a gas. Also, they are not as close to each other as a solid, but not as far away from each other as a gas.
So to a giant the size of the sun, a "liquid" would be apples which move a fair bit and are not to far away from each other!
