States of Matter & KMT
This state of matter has particles that vibrate in place and are held together by strong attractive forces in a rigid structure.
Solid
This is the formula used to calculate density.
Density = mass/volume
This scientist proposed that all matter is made up of tiny, indivisible particles called atoms.
Dalton
This type of matter is made up of only one type of particle and cannot be broken down into simpler substances.
Element
This type of property can be observed without changing the chemical composition of matter.
Physical property
According to KMT, adding this to matter causes particles to move faster and farther apart.
Energy
This method is used to measure the volume of irregularly shaped objects by submerging them in fluid.
Displacement
This subatomic particle has a negative charge and moves around the nucleus in energy shells.
Electron
This type of mixture allows you to visually distinguish between different components.
Mechanical mixture
This type of change produces new substances with different properties.
Chemical change
This phase change occurs when a solid gains enough energy to skip the liquid state and turn directly into a gas.
Sublimation
If an object has a density less than water (1.00 g/mL), it will do this in water.
Float
This scientist's gold foil experiment led to the discovery of the nucleus.
Rutherford
This type of pure substance consists of two or more elements chemically joined in a specific ratio.
Compound
Formation of gas bubbles, temperature change without heating, and change in color are examples of these.
Indicators of chemical change
This state of matter, found in the Sun and lightning, consists of positively and negatively charged particles.
Plasma
The units commonly used to express density for solids and liquids.
g/cm³ and g/mL
These two particles are found in the nucleus and have a mass of approximately 1 atomic mass unit each.
Protons and neutrons
This type of mixture appears uniform and you cannot distinguish the different components with the naked eye.
Solution/homogenous mixture
This chemical property describes a material's ability to catch fire and burn in air.
Combustibility
When energy is removed from a gas, particles slow down and move closer together until this phase change occurs.
Condensation
This substance is an exception to the rule that most substances are more dense in solid form than liquid form.
Water (ice)
This scientist proposed that electrons occupy specific energy levels or shells around the nucleus.
Bohr
These can be separated by physical changes and are made up of different particles mixed together but not chemically joined.
Mixtures
This type of property can be measured numerically, such as boiling point, melting point, or density.
