Density
What is the formula for density
D = M/V
Define Density
The amount of mass in a given volume
Thermal energy speeds up the motion of fluid particles
True
What is the density of water
1 g/ml or 1g/cm
Milk has a volume of 35 mL and weighs 55g, what is the density?
1.5714 g/mL
Define Thermal Energy
Heat energy
Thermal energy makes particles move closer together
False
What is the difference between weather and climate?
Weather is what is happening right here, right now. Climate is predictable weather over a long period of time.
The mass of copper is 15g and the volume is 25 mL, what is the density?
0.6 g/mL
Define Kinetic Energy
Energy in motion
There are more particle collisions when thermal energy is added to a fluid
True
Describe Convection currents in the atmosphere
Convection currents form when cool air rises and hot air sinks
The mass of gold is 30g and the volume is 7mL, what is the density?
4.2857 g/mL
Define Radiation
rays of energy that travel long distances
Particles increase in size when you add heat
False
Which place receives more radiant energy, the poles or the equator?
The equator
How would the following liquids layer?
-Red: Density = 3.5 g/mL
-Blue: Density = 4.7 g/mL
-Green: Density = 3.6 g/mL
-Yellow: Density = 2.4 g/mL
Blue, Green, Red, Yellow
Define Convection
transfer of heat by movement of fluids
Anything with a density greater than 1 g/ml will float in water
False in will sink!
What are the two factors that contribute to a regions climate?
Latitude and Solar Angle
