What makes something a solid?

A solid keeps its shape and volume because its particles are closely packed and have a fixed position.

Is water a solid, liquid, or gas?

Water can be all three, depending on the temperature: it's a solid (ice) when frozen, a liquid (water) at room temperature, and a gas (water vapor) when heated.
