What will happen to a fluid if it becomes less dense?
It will rise (the increased energy pushes the particles farther apart)
The ice water would sink to the bottom because it is more dense
Define meteorology
the study of Earth's weather
Which letter would layer on the top?
A: 50 mL, 100 g
B: 150 g, 76 mL
B
(A: 100g/50mL=2g/mL, B 150g/76mL=1.97g/mL)
Order the solutions how they would layer in a straw:
2.3 g/mL
2.4 g/mL
2.04 g/mL
2.04 g/mL
2.3 g/mL
2.4 g/mL
What will happen to a fluid if it becomes more dense?
It will sink (the decrease in energy allows the particles to come closer together)
Define convection.
Energy transfer where hot fluid rises and cold fluid sinks creating a cycle
Define electromagnetism
The interaction of electric and magnetic fields
Which letter has the greatest density?

B: 45 g, 90 cm^3
C: 28 mL, 80 g
C
(A:55g/50cm^3=1.1cm^3
B:45g/90cm^3=.5cm^3

What are two ways you could change the density of a material?
Add energy into it (in our examples, heat), using physical force (ex: compressing/ expanding), adding a substance to it (ex: adding salt to water)
A lava lamp works because of convection. Explain what would happen to the fluid inside using the concept of density and kinetic energy.
There is a heat source at the bottom of the lava lamp. It transfers kinetic energy into the fluid. As the kinetic energy increases, the density decreases and the fluid rises.
As the fluid reaches the top it starts to cool (lose kinetic energy to the environment) and become more dense. It sinks to the bottom to be reheated.
What is a group of flamingos called?
A stand!
