The correct option is B, a prediction. It is the principle that will lead us to a theory.
Total mass of water = 2 +16 = <u>18g</u>
As mass needs to be conserved
Answer:
Elements can be described by various properties, and identified by their boiling and melting points. For example, gold melts at
Elements can be described by various properties, and identified by their boiling and melting points. For example, gold melts at 1,064ºC and boils at 2,856ºC. Does boiling point depend on the mass present?
A. No; chemical properties stay the same regardless of mass.
B. No; physical properties stay the same regardless of mass.
C. Yes; physical properties can change when mass increases or decreases.
D. No; qualitative properties like boiling point stay the same regardless of mass.
Explanation:
The answer is D. Liquid to Solid
An educated guess is called estimation
