Particles
What are the tiny building blocks that make up all objects?
What are Particles? (or molecules or atoms)
What are the three main states of matter?
What are solids, liquids, and gases?
What is the formula for density?
What is density = mass/volume?
What is a characteristic that can be observed without changing the substance?
What is a physical property?
What is the smallest unit of an element that maintains the properties of that element?
What is an atom?
What is a group of two or more atoms bonded together called?
Answer: What are molecules?
What happens to the particles of a substance when it changes from a solid to a liquid?
What is they move apart?
This is what an object does if it has a density greater than water.
What is sinking?
What type of property describes how a substance reacts with other substances?
What is a chemical property?
What is the process called when a solid turns directly into a gas?
What is sublimation?
In a solid, how are the particles arranged?
What is particles tightly packed together?
What state of matter has a definite shape and volume?
What is a solid?
This is what happens to the density of an object if you increase its volume while keeping its mass the same.
What is decrease?
This property might help you determine if an object will sink or float
What is density?
What tool do we commonly use to measure the mass of an object?
What is a scale?
On a scientific model, this element helps us understand drawings of particles that correlate via symbols, colors, or other indicators
What is a key?
In which state of matter do particles move freely and fill the container but have no definite volume?
What is a gas?
What is the unit of measurement for density in the metric system?
What is grams per cubic centimeter (g/cm³)
What property describes how well a substance can conduct electricity?
What is electrical conductivity?
What is it called when matter changes from one state to another?
What is a phase change?
What is it called when particles move from a liquid to a gas?
What is evaporation?
What is the term for the process of changing from a gas to a liquid?
What is condensation?
If two objects have the same mass but different volumes, which one has a higher density?
What is the one with the smaller volume?
This property helps to describe the amount of light reflected off an object
What is luster?
What is the term for a visual representation of data, often in the form of a bar chart or a line graph?
What is a chart?
