Stored energy, or energy that an object has because of its position or condition, is called __________________.
Potential Energy
Temperature is measured with a __________________________.
Thermometer
Temperature is usually measured in degrees Fahrenheit or ____________________.
Celcius
Cooling a substance causes it to __________________ thermal energy.
lose
energy that an object has because of its motion is called ____________________.
Kinetic Energy
___________________ is the ability to do work.
Energy
A ____________________ is the amount of thermal energy needed to raise the temperature of 1g of water 1 degree Celsius.
Calorie
The particles in a cool substance move _______________________ and are attracted to each other more, causing the substance to change states.
Slower
The total kinetic energy of the particles in a substance is called __________________.
Thermal Energy
The ability of a substance's particles to move faster and expand without changing states is called ____________________ ___________________.
Thermal Expansion
The thermal energy of a substance is determined by it's _________________ and ________________.
temperature and mass
The measure of the average kinetic energy of the particles in a substance is called ____________________________.
Temperature
Almost every substance _________________ when heated.
Expands
Heating a substance __________________ thermal energy.
adds
Thermal energy is measured in _______________________.
Calories
Almost every substance __________________ when cooled.
Contracts
When a substance is heated, the particles move ________________ and farther apart, causing the substance to change states.
faster
How does temperature affect thermal energy?DOUBLE POINTS!!
Particles in a substance move faster when the temperature increases. A higher temperature means the substance has more thermal energy than when its at a lower temperature.
How does mass affect thermal energy?
DOUBLE POINTS!!
More mass means that the substance has a greater number of particles so it would have a greater total kinetic energy, or thermal energy.
