Heat 1
What is Heat Energy?
Heat Energy is the energy for fast moving particles
What is the particle theory
Q: Give an example of thermal equilibrium in everyday life.
A: Ice melting in water until both reach the same temperature.
What is Greenhouse Effect
A process that occurs when the gases in the earth's atmosphere trap the sun's heat
What is temperature and how is it measured?
The average energy of particles in a solid, liquid or gas. Measured using Celsius or Farhenheit
According to the Particle Theory, this happens to particles when they are heated up.
What is they move faster (and spread apart)?
Does water contract or expand when it freezes
it expands
Name a type of renewable energy
solar energy, hydro energy, wind energy
What is Albedo
Albedo is how much light is reflected without being absorbed.
The Sun is an example of what kind of heat transfer
Radiation
Fluorinated gases
What is an urban heat island?
A: A city that is warmer than surrounding rural areas due to human activity.
Which of these is NOT a renewable energy source?
a) Natural gas b) Solar energy c) Hydro energy
d) Wind energy
A) natural gas
Q: What is radiation?
A: Movement of heat energy through electromagnetic waves.
Wind is caused by what?
Convection
Q: What is thermal expansion?
A: The tendency of matter to change volume and density with temperature changes.
Q: Which type of heat transfer allows you to feel warmth from a campfire without touching it?
radiation
Plants cool the environment through transpiration. They also absorb carbon dioxide from the atmosphere
Name at least 2 greenhouse gases
Carbon dioxide, methane (also nitrous oxide, fluorinated gases).
the process of water movement through a plan and the loss of water, mainly through leaves
Q: State the Law of Conservation of Energy.
A: Energy cannot be created or destroyed, only converted from one form to another.
Why is the ozone layer important?
It protects the earth from ultraviolet radiation
Q: Explain why Bryan dropped his mug after pouring hot coffee into it using scientific terminology.
A: Heat transferred from the coffee to the mug by conduction, making the mug too hot to hold.
Describe convection, conduction and radiation are involved with boiling a pot of water over a campfire.
