Intro to Phys Sci
Anything that has mass and takes up space.
What is matter?
The amount of space that matter takes up in a given container.
What is volume?
What is a solid?
What is melting?
A push or a pull.
What is force?
The basic unit from which all matter is made.
What is an atom?
This type of mixture has a uniform composition throughout, like salt dissolved in water, making its individual components indistinguishable.
What is a homogenous mixture?
This has a definite volume, but no shape of it's own.
What is a liquid?
The change of state from a liquid to a solid.
What is freezing?
This is the ability to do work or cause change.
What is energy?
Substances that are made up of only one type of atom.
What is an element?
This type of energy comes from the motion of particles within a substance and increases as temperature rises.
What is a gas?
The change of state from a liquid to a gas.
What is evaporation?
This is the energy an object possesses due to its motion, and it increases with both mass and speed.
What is kinetic energy?
A group of two or more atoms held together by chemical bonds.
What is a molecule?
In this type of mixture, the different components are visibly distinct, like a salad or a mixture of sand and iron filings.
What is a heterogenous mixture?
This is the fourth type and most abundant form of matter in the universe, but found less on Earth.
This is the reverse of vaporization, changing state from a gas to a liquid.
What is condensation?
These changes involve physical movement or deformation of an object, such as bending, breaking, or stretching, without altering its chemical composition.
What is mechanical energy?
Two or more substances that are together in the same place, but their atoms are not chemically bonded.
What is a mixture?
This is the measurement of the mass of a material in a given object and is calculated by dividing an object’s mass by its volume and determines how tightly matter is packed together.
What is density?
This measure of a fluid’s resistance to flow is high in substances like honey and low in substances like water.
What is viscosity?
Gaining or losing this is the main cause of any change of state.
What is thermal energy?
This fundamental principle states that energy cannot be created or destroyed, only transformed from one form to another.
What is the Law of Conservation of Energy?
