Density
What does density ratio compare?
The mass of an object to its volume
What is a fluid in science?
substance that changes shape to fit its container and can flow.
Each color of fluid had a different density.
Why did the experiment with the four colored water layer?
Heating a substance causes molecules to speed up and spread slightly further apart, occupying a larger volume that results in a decrease in density.
How does heat affect density of fluids?
What is the definition of mass?
The amount of matter in an object or sample
What is a convection cell?
The mass of fluids flowing in a cycle.
A representation of an object or process to help others understand your thinking.
What is a model in the context of science?
Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density.
How does cooling affect density of fluids?
What is volume?
The amount of space an object occupies.
How is convection best described?
The transfer of heat through the movement of fluids creating a cycle
Why did the yellow fluid weigh more than the red fluid?
The yellow fluid had more particles (mass) than the red fluid.
The circulation of air in the atmosphere is primarily driven by convection. Convection refers to the process of heat transfer through the movement of a fluid (in this case, air). Also, gas moves from a region of high pressure to a region of low pressure.
How do gasses flow in the atmosphere?
What is the definition of density?
The amount of mass in a sample of matter compared to the volume of that sample.
What is kinetic energy?
The energy of motion
It stayed at the top because it was less dense.
What did the red heated water do in the experiment?
What is the relationship between layering of fluids and density?
More dense fluids sink in less dense fluids and less dense fluids float in more dense fluides.
1 g/mL3
What is the density of water?
The transfer of energy from one object to another.
What is energy transfer?
A more dense fluid will sink in a less dense fluid and less dense fluid will float on a more dense fluid.
What is the relationship between the layering of fluids and density?
This is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other.
What is Thermal energy (also called heat energy)?
