Water has very unique physical properties; most of them brought on by the hydrogen bonding within water. Water is strongly polar, meaning the water molecule has a distinct positive end and negative end, caused by unshared electrons on one side of the molecule. This causes the positive end of one water molecule to be attracted to the negative end of another water molecule. This inter-molecular attraction gives water surface tension, explains why water sticks to the sides of containers, forms spherical droplets, expands when it freezes, and is why snowflakes are six-sided.
Temperature and pressure.
It is a physical change as the identity of the substance remains the same.
When someone mentions water polarity, they are talking about the intermolecular properties of water. Water is a polar-covalent bonded molecule which means that even though the hydrogens are sharing electrons with the oxygens, the electrons will be attracted slightly more to the element with the bigger nucleus.
A physical change. It came from water and is still water.Physical - the water changes from a gas,water vapour, to a liquid, rain.

It has no color, taste, or scent.

A Bethesda is a poetic term for a location whose waters are supposed to have curative properties.
Yes, that is correct
Melting icebergs anywhere on earth contribute to elevated ocean levels. This is also true in the Southern Ocean, which surrounds Antarctica.

physical weathering is weathering that you can reverse and chemical weathering is where you can' reverse it.
