The greater the mass of an object, the more of this is needed to change its motion.
What is force?
This state of matter has properties of both liquids and solids and is made of long chain molecules.
What is a liquid crystal?
The number of these in the nucleus determines the identity of an element.
What are protons?
Mixing vinegar and baking soda causes a reaction producing this gas.
What is carbon dioxide?
