Question | Answer |
Define matter | anything that has mass and takes up space. |
How is volume calculated? | liquids- in a graduated cylinder, regular solid shape volume = L x W x H, irregular solid shape-water displacement 1 mL = 1cm cubed, |
Define inertia | the tendency of an object/substance to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the object. |
Identify how mass is related to inertia | Mass is a measure of inertia |
What are some differences between WEIGHT and MASS? | Mass -Is always a constant at any place and time,measured by a balance, unit kg g & mg Weight-measured in newtons by a spring scale, varies depending on location |
Mass | is a measure of how much matter an object has. |
Weight | is a measure of how strongly gravity pulls on that matter. Thus if you were to travel to the moon your weight would change because the pull of gravity is weaker there than on Earth but, your mass would stay the same because you are still made up of the s |
What is density | is the amount of matter in a given space or volume |
How is density calculated? | mass / volume |
What units are used to measure density? | of a solid is g/cm cubed or kg/m cubed |
What is physical change | is a change that affects one or more physical properties of a substance |
Difference between physical and chemical change | ask kelly |
Identify some common physical properties (malleability, solubility, etc.) | bent nail, clear liquid |
Identify some common chemical properties(i.e. flammability) | reactivity, rust |
