Science Study Notes on Density and Factors Affecting Reactions

Flashcards covering key concepts related to density, mass, volume, and factors affecting chemical reactions.

What factors affect the rate of reactions?

The factors include amount of reactants, surface area, and temperature.

Define Density.

Density is how tightly packed the particles are in a substance.

Define Mass.

Mass is how much matter is in an object, typically measured in kg.

Define Volume.

Volume is how much space an object occupies, often measured in cubic units.

How does the state of matter affect density?

The state of matter affects density because solids have tightly packed particles, while liquids have loosely packed particles.

What is the formula to calculate density?

Density is calculated by dividing mass by volume.
