An educated guess in the scientific process?
What is the Hypothesis?
The law of conservation of energy states this
What is energy is never lost, only changed?
The total amount of kinetic energy of the molecules in a system
What is Thermal energy?
The measure of the amount atoms and molecules in an object
What is the Mass?
In this type of change no new substance is formed?
What is a physical change?
The part of an experiment that stays the same
What is the constant?
The energy in food is this type of energy
What is chemical energy?
The average amount of energy in a system
What s the temperature?
This part of the atom has no charge, or is neutral?
What is the neutron?
In this type of change, a new substance is formed
What is a chemical change?
The part of an experiment that changes
What is the variable?
Mechanical energy is made up of these two types of energy
What is potential or kinetic?
Heat moves in this direction
What is from hot to cold?
This part of the atom has a negative charge
What is the electron?
The reason that ice floats in water is because it's less this
What is dense?
This type of data you can observe, such as how it looks, smells or tastes
What is Qualitative?
Potential energy is determined by these
What are chemical composition and height?
This type movement of energy is happens when objects are touching
What is conduction?
This nucleus of an atom is made of these two parts
What a proton and neutron?
The forming of a gas by mixing two substances is evidence of this type of change
What is chemical?
This type of data is specific and must be measured
What is Quantitative?
This energy is store in the nucleus of atoms
What is nuclear energy?
This type of energy transfer is by electromagnetic waves, such as sunlight
What is Radiation?
The atomic number tells us how many of these an atom has
What is a proton?
