This is a measure of how much matter is in an object.
What is mass?
This is the volume of a rectangular prism that is 10 cm in length, 2 cm in width, and 5 cm in height.
What 100 cm3?
This is a physical property of paper.
What is color, shape, size, mass, weight, density, or volume? (answers will vary; teacher determines correct or incorrect)
This occurs when a substance changes its form or appearance but does not change its identity.
What is a physical change?
This is how you can chemically change a piece of paper.
What is burn it?
This is a measure of how much space an object takes.
What is volume?
This is the volume of an object using the water displacement method that had a starting volume of 15mL and a final volume of 25 mL.
What is 10 cm3?
This is the type of change when sugar dissolves in lemonade.
What is a physical change?
This is how you could physically change a piece of paper.
What is tear/rip/cut it, write/draw/color on it, get it wet, or crumple it up?
This is the chemical property of burning an object.
What is flammability?
This is a measure of how tightly packed an object is.
What is density?
Two objects that have the same volume MUST have the same mass. (T/F)
What is false?
This is the difference between a physical change and a chemical change.
What is a change in appearance for a physical change, and a change in identity (what the substance is/becomes something new) for a chemical change?
This is the reason why erosion of soil IS a physical change.
What is the soil is just moving location? It is still soil.
This is what happens when an object made of iron oxides. (like an iron nail or part of a car)
What is rusting?
This is a measure of the pull of gravity on an object.
What is weight?
This is the tool, unit, and process of finding the density of a marble.
What is fill a graduated cylinder with water, put in the marble, and find the difference between the starting volume and final volume of the water in cubic centimeters (cm3)?
These are 3 signs that a chemical change has taken place
What are bubbling/fizzing, change in temperature, new color, light is given off, and a precipitate formed?
This is the reason why baking a cake is NOT a physical change.
What is the ingredients (such as flour, sugar, eggs) turn into new substances with new properties when high heat is added to them; so it is a chemical change?
Rusting or oxidizing is an example of this chemical property.
What is reactivity?
This DESCRIBES an object of substance.
What is a property?
This is the density of a liquid in which 2 objects were placed. Object 1: mass 11g, volume 12cm3 and floats. Object 2: mass 30g, volume 27cm3 and sinks
What is .92mL - 1.10? (greater than .91 but less than 1.11)
This is the reason why a change in state of matter (example ice, water, water vapor) is a physical change.
What is the substance is still the same? (It is still H2O whether it is a solid/ice, water/liquid in a cup, or water vapor/gas)
This is a helpful question you could ask to determine if a change is physical?
What is .......? Examples: Was there a change of state of matter, size, shape, texture etc? Did just the appearance of the substance change?
This is the 3rd chemical property other than flammability or reactivity.
What is pH?
