Matter
Question | Answer |
---|---|
What are the three states of matter | gas, liquid, solid |
What is the difference between chemical and physical change | Chemical is how matter can can change into a new kind of matter. Physical is how matter looks, feels, smell, sounds, and taste. |
What is matter | Matter is anything with mass that takes up space |
Define volume, density, mass, weight, atom, molecule | Volume is how much space matter takes up. Density is the mass of an object to its volume. Mass is how much matter is in an object. Weight measures how heavy something is.Atoms are the smallest part of an element. Molecules happen when two+ atoms join. |
What unit of measure do we normally use to measure volume | cm3/cubic centimeters |
What unit of measure do we normally use to measure mass | grams or kilograms |
Explain how you read a graduated cylinder | You put the water level at your eye level and then tell the amount of water that is in the graduated cylinder in millimeters. |
What is curved water inside a graduated cylinder called | meniscus |
Explain why mass remains the same on a different planet while weight changes | Mass is how how much matter is in an object which never changes unless the substance gains weight, looses weight or brakes. and weight is the gravity pull on an object which changes because every planet has a different gravity pull. |
How do you find density | mass divided by volume |
how do you find volume | LxHxW |
What does cm3 stand for | cubic centimeters |
what does g stand for | grams |
what does mm stand for | millimeters |
what does cm stand for | centimeters |
Find the volume H=10cm W=5cm L=15cm | 10x5x15=750 |
Find the density W=10cm H=5cm L=15cm Mass=1200g | volume=750cm Mass=1200g 1200 divided by 750=1.6 |
Which is true about density A= Density is equal to the amount of mass in an object B= Objects with a lesser density than water will float C= density is a physical property | B |
A kind of mixture in which the different parts are very evenly mixed is called a... | solution |
Two or more compounds or elements together in the same place is called a... | mixture |
