M2.1 Flashcards
What’s the difference between a scalar and vector quantity?
A vector has both magnitude and direction whereas scalar only has magnitude
Examples of vector quantities
Acceleration, force
What’s a vector
A vector is a quantity with both magnitude and direction
What’s deposition
Transition from a gas to solid
What’s sublimation
Solid to gas’s without passing through liquid phase
What’s the difference between endo and exothermic reactions
Exo releases heat where as endo takes in heat
How many known elements are in the periodic table

Difference between a compound and a mixture
Compounds are chemically bonded whereas mixtures aren’t
