D. Protons, Atomic number is the number of protons in an atom.
Answer:
The cooler water is denser
Explanation:
Convection drives the boiling of water placed on a stove in a kettle.
During convection, heat is circulated by density differences in portions of a fluid.
Convection is a form of heat transfer in fluids especially gas and liquid.
- In boiling water, the heat is supplied to the base of the stove.
- The water at the bottom on heat becomes lighter as the molecules gain more kinetic energy.
- The colder part of the water on top sinks to replace the less dense on below.
- This exchange sets up convection cells in the kettle.
It’s ionic
KCl(at)
Potassium chloride
I believe that would be oil and vinegar.
B) land cools off much faster than water (creating a air region of high density above land and lower density above sea)
