The mass of one cubic centimeter of water at 4c is one ___1___. Scientists commonly use two equivalent units of temperature, the degree __2___ and the ____3___.

You have the first considerably in error. I will be happy to critique your thinking.

1. not quite. 1 cc of water has a mass of 1 gram.

2. the degree Celsius and Kelvin ALTHOUGH I don't think they are equivalent. A degree Celsius IS equal to a degree on the Kelvin scale and that's probably what the questioner meant. To interconvert, K = 273 + C.
