⚖️ Density and Mass-Volume Relationships
Master the concept of density—one of the most important properties of matter in physics. Learn how mass and volume relate through the density formula, perform calculations, compare materials, and understand how temperature affects density. This quiz covers the essential Grade 8 density concepts from the Ontario curriculum, preparing you to identify substances and predict whether materials will float or sink. **What you'll learn:** - Define density and apply the mass-volume formula - Calculate density, mass, or volume from given measurements - Compare densities of common materials - Understand density variation with temperature - Use density to identify substances and predict material behavior
