Define radiation
transfer of energy without any movement of matter
Define Geothermal energy
Energy from the interior of the Earth
Is estimating temperature with your hand reliable and why.
No, because your body only senses relative temperature
What is the difference between heat and Temperature
Temperature is the average energy in a particle heat is the total energy in a particle
What is the 4th state of matter
plasma
What are the features of energy transfer systems
Energy source, Direction of energy transfer, transformations, Waste Heat Control systems
List five sources of energy
solar wind geothermal Mechanical thermal electrical chemical Hydro Hydro-electrical
What are the 4 types of temperature measuring devices
Thermocouple, Bimetallic Strip, Infrared Thermogram, Recording Thermometer
What are the 5 ideas of the Particle Model of Matter
All substances are made of tiny particles.
All particles have spaces in between them.
Particles are always in motion.
The motion of particles increases or decreases when temperature decrease or increases
Temperature indicates the average energy of the particles in motion in a substance.
Give one reasons why sulfur dioxide is dangerous
It irritates eyes, nose, and throat
What is the speed that radiation travels through empty space
300 000 km/s
What are two reasons hydro-electrical dams affect the environment
Some plants might not grow there anymore.
An organism that used to live there has to go somewhere else
When did Galileo invent his air thermometer
Around the 1600s
Is energy a substance
No.
Is liquid gold more expensive than solid gold
They are the same
The EMR spectrum from smallest wavelength to biggest
Cosmic, gamma, UV, Visible Light, Infrared, Microwaves, Radio waves
What is the difference between Hea capacity and specific heat capacity
Specific heat capacity is describing a material heat capacity describes an object
What is a Thermocouple
Two wires of different metals are twisted together. When the tips are heated an electric current is produced. This electrical current can turn on and off a switch or valve.
What does the law of conservation of energy state
It states energy cannot be created or destroyed but can be changed from one form to another
When a fire burns without oxygen______ is released
Carbon Monoxide
What are the characteristics of all radiation waves
They behave like waves
They can be absorbed and reflected by objects
They travel across empty space at the same very high speed
What type of sublimation is gas to solid and give an example
Deposition frost patterns on a window answers will vary
