U5.PS4.B3: Explain kinetic theory and the impacts on fluids. -changes air pressure (i.e., high/low) -causes fluids (water, gas) to rise & sink -changes density -causes evaporation
1. Explain how the movements of molecules change the temperature of matter. For example, how the speeds of molecules cause water to be cold or hot.
2. Explain how the movements of molecules cause fluids (i.e., water & air) to rise and sink. For example, explain why hot air rises and cold air sinks.
3. Explain why fluids (i.e., air & water) sink when the density of that fluid increases and why they rise when the density decreases.
