Answer:
Dispersion forces
Relative molecular mass
Explanation:
Alkanes experience only dispersion forces. Dispersion forces increase with increasevin the relative molecular mass of the compounds. Hence a higher relative molecular mass implies greater dispersion forces and a greater boiling point.
Answer:
If one astronaut used more force, then that one would be faster than the other. The independent variable is force. The dependent variable is speed.
Explanation:
Force is what is to be changed. Speed is what is being measured.
IV = Changed/factor DV=Measured/Changes by factor
Answer:
Burning a match
Explanation:
A chemical change is where a substance is changed into one or more substances. Basically, a chemical change changes the form of a substance. While, a physical change such as ripping a piece of paper in half will still be a paper just in half(nothing is changed).
