Chemistry question

Please correct me if I am wrong.

Describe a chemical or physical property:

1.Aluminum Metal has a specific heat of 0.900 j/g*C....chemical property?
2.Sodium hypochlorite (bleach) will remove the color from a dyed shirt...chemical property?
3.Sugar will dissolve in water. physical property?
4.Iron is transformed into rust in the presence of air and water. chemical property?
5.Dry ice sublimes at -78.6*C. physical property?

1. is physical because it doesn't change the substance. all it measures is how much heat it takes to change somethings temp by a certain amount
