What are the constants between salt water and fresh water in regards to freezing?
The difference is that fresh water will freeze at 0.c and salt will freeze to a lower temperature due to the presence of impurities (salt).
Does an ice cube have more or less heat than a firework spark?
Less. Firework spark is generated by fuse friction, ice by freezing water and the water expands.
What ingredients in salt makes water's boiling point lower?
It's not the ingredients in salt, but the presence of the salt itself. The salt holds the water in because of its attractive forces and blocking of the water throughout the mixture. Any soluble substance will affect the boiling and freezing points of any solvent based on how big the solute particles are, and the boiling/freezing pt constants, K, for the solvent.
Is the process of repeating freezing that cracks rock mechanical or chemical?
It would be physical because a chemical change in the rock would be where the bonds are broken and formed to create new bonds and a new product is generated.
What is the plural form of freezing?
