Energy Fundamental
This is the ability to cause change and is measured in Joules.
What is Energy
A droplet, a cup, and a bucket of water are all at the same temperature (30 °C); This one has the greatest amount of thermal energy.
This describes the movement of particles in a solid rock.
What is vibrating in place
This type of heat transfer requires direct contact and is responsible for transferring energy to Warren's hand from the hot metal handle of a pan.
what is conduction?
This law states that energy cannot be created or destroyed.
The Law of Conservation or Energy
Examples of this include fusion or fission of nuclei, used in atomic bombs or the sun.
What is Nuclear Energy
This measurement is the average kinetic energy of the particles that make up a substance.
What is temperature?
This state of matter has the highest kinetic energy
what is gas?
The process by which heat transfers through liquids and gasses via density differences - the particles flow/move.
What is convection?
As a ball rolls down a ramp, the potential energy of the ball decreases and is converted into this.
Kinetic energy
The type of energy conversion shown when a person rubs his or her hands together rapidly.
What is Kinetic to Thermal Energy?
This describes the thermal energy of a substance.
What is the total kinetic energy of its particles.
As hot liquid glass cools and becomes solid glass, this describes the change in particles (the change in particle motion)
they move slower (or they have less kinetic energy)
Metals are good at transferring heat and are classified as this type of material.
What are conductors?
Why is a perpetual motion machine impossible?
energy is always lost when transformed.
This is the energy conversion shown when a candle is burning.
What is chemical energy to thermal and light energy
Temperature can be measured using a thermometer in these three units.
What is Celsius, Fahrenheit, and Kelvin
This best describes how liquid water is different from water vapor (a gas), regarding particle energy.
The liquid has less kinetic energy (or the liquid particle move slower)
Wood does not conduct heat well, making it a good one of these
What is insulator
The percentage efficiency of a light bulb that receives 60 W of electrical energy and converts 3 W to light energy.
What is 5%
This type of energy, along with heat, is the main output when chemical energy in gasoline is converted by an automobile engine.
What is mechanical energy
This happens to waters temperature as it goes from solid to liquid and liquid to gas - even though heat is still being added to it. (think about the temp/time graph for water.)
What is, the temperature does not change during state change?
This phenomenon is described as having "no particles move" and is an unrealized state according to the Kinetic Theory of Matter. It is a temperature we have never seen on Earth...it's very very cold.
what is absolute zero
This type of energy travels to Earth from the Sun.
What is electromagnetic energy?
(thermal energy DOES NOT travel to Earth from the Sun! Thermal energy is created when this electromagnetic radiation is absorbed by Earth's surface and atmosphere. )
When a flashlight battery runs out, its energy has changed to these two forms - from what type?
Thermal and light energy - from chemical energy.
