Nitrogen
What causes convection?
Uneven heating
Name a unit of heat other than joules
Calories
Name 2 examples of mechanical energy.
A flying bird and a moving car.
Name the difference between thermal energy and temperature.
Thermal energy - amount of kinetic energy
temperature - speed of kinetic energy particles.
What happens when rise in altitude?
Air pressure decreases.
Name 3 types of winds
Trade winds, polar easterlies, westerlies, jet streams,etc.
1 calorie = ? joules
4.18 Joules
What is the law of conservation of energy?
The law of conservation of energy states that energy can't be destroyed.
What is conduction, convection, radiation?
Conduction - heat transfer through contact.
Convection - heat transfer through liquid or gas
Radiation - heat through E.M waves
Give 1 example of thermal expansion.
Hot air balloon.
What is the Coriolis effect?
A phenomenon which happens in Earth's atmosphere when wind deflects the path of an object, causing it's path to curve.
How do you find the calories in an object?
Use a calorimeter
As kinetic energy and potential decreases what increases?
Thermal energy
How does heat transfer?
From hot to cold.
What is specific heat?
Different rate of heating and cooling
What causes the Coriolis effect?
Earth's rotation.
Removing or adding energy result in a change of _____?
State of matter.
Potential energy is determined by...
Positional energy, chemical composition.
What is the kinetic theory of matter?
It states that particles are always in motion and move at different speeds.
Name 3 forms of radiation.
X-ray, UV rays, infrared.
What is the wind directions in both hemispheres for westerlies?
North hemisphere - Southeast
South hemisphere - Northwest
Heat transfers to an object until _____?
They both reach the same temperature.
