Section 2a
One shot
What is the term for the total kinetic energy of the particles in a substance?
Thermal energy
Three Shots
What is the term for the average kinetic energy of the particles in a substance?
Temperature
One Shot
What is the main source of heat for the world?
The Sun
Two Shots
What type of energy can be obtained from the Earth's interior?
Geothermal
Three Shots
Why is nuclear energy considered non-renewable?
Nuclear energy is considered non-renewable because it is generated from a non-renewable resource, uranium
Three Shots
What is the term for when a material’s volume increases as its temperature increases?
Thermal Expansion
One Shot
What happens to the movement of particles when heat is added?
They move faster OR they move further apart
Three Shots
What are the three components of an active solar heating system?
A collector, a heat storage unit, and a heat distribution system
Three Shots
How does pink insulation in walls reduce heat loss?
Insulation contains small air pockets that stop convection currents from establishing, and trapped air reduces heat loss by conduction and convection.
Two Shots
What is one disadvantage of using wind energy?
Wind energy is unreliable and inconsistent. Aesthetics. Harms organisms.
Two Shots
What is the process called when thermal energy is added to a solid to create a gas?
Sublimation
Three Shots
What two states of matter allow for convection to occur?
Liquids and Gases
Two Shots
What does a passive solar heating system use to store solar energy?
The materials in the structure
One Shot
What does the term "thermo" mean in the context of a thermostat?
heat
One Shot
What is one advantage of using fossil fuels?
Fossil fuels are easy to obtain and transport. Create jobs, contain a lot of energy.
One Shot
What is the state of matter where particles have low energy, vibrate in place, and have a strong attraction?
Solid
Two Shots
What is the term for the transfer of heat between substances that are in contact with each other?
Conduction
One Shot
What is a device that maintains a specific temperature in a room?
Thermostat
One Shot
What is R-value?
The rating given to how good of an insulator specific material is.
One Shot
What are the two types of natural resources?
Renewable and non-renewable
Three Shots
If two objects have the same temperature, what determines which has the most thermal energy?
The number of particles
Two Shots
What happens to the volume of a solid when it cools down?
Decreases
Two Shots
How does a bimetallic strip work?
The two metals that are laminated together contract and expand at different rates.
Three Shots
What is the term for a photo taken to diagnose heat loss in a building?
Thermogram
Two Shots
What are fossil fuels made from?
Fossil fuels are made from the remains of plants and animals from millions of years ago
