Introduction to Physical Science
The third step in the scientific process. An educated guess or a possible explanation of a problem.
What is a hypothesis?
The three physical states of matter.
What is solid, liquid, and gas?
This type of heat transfer occurs only in a medium such as air or water.
What is convection?
The periodic table is organized according to this.
What is atomic number?
This state of matter has the highest kinetic energy.
What is gas?
The fifth, or last step in the scientific process.
What is the conclusion?
What is radiation?
The inventor of the modern periodic table.
Who is Dmitri Mendeleev?
The electric charge of a electron.
What is negative?
This type of reaction is where energy is absorbed (think: ice pack that is used when you have an injury).
What is an endothermic reaction?
A change that alters the form or appearance of a material but does not make the material into another substance.
What is physical change?
This type of heat transfer is through actual contact of two objects.
What is conduction?
These 3 pieces of information are included for each element in the periodic table.
What are atomic number, atomic mass and atomic symbol?
These 2 particles make up the nucleus of an atom.
What are protons and neutrons?
This type of reaction is where energy is given off or released (think: hand warmers that you put inside your gloves).
What is an exothermic reaction?
A change in which one or more substances combine or break apart to form a new substance.
What is a chemical change?
These 3 main scales are used to measure temperature.
What are Fahrenheit, Celsius and Kelvin?
The periodic table is arranged in rows called these.
What are periods?
This is the international unit of measurement of distance or length.
What is meter?
There are two types of changes. Combustion is an example of this type of change.
What is a chemical change?
The change of state from a solid directly to a gas, without going through the liquid state.
What is sublimation?
The average kinetic energy of all the particles in an object.
What is temperature?
Electrons in the last orbital or shell are called these.
What are valence electrons?
This is the international unit of measurement of mass.
What is kilogram?
