Light and Matter
Light travels in these types of lines.
What are straight lines?
Light can _________ energy into a system.
What is transfer?
These can be seen moving into and out of the area where it hailed.
What are clouds?
This is the amount of mass in a substance per unit volume.
What is density?
This represents the behavior of air in the bottle when placed in cold water.
What is the air molecules slow down and take up less space, making the air denser
This is a set of parts that work together (interact) toward a goal or outcome.
What is a system?
When light that shines on a surface is not reflected or transmitted, it is _____________, which warms the matter it is shined on.
What is absorbed?
These are made of ice, often in layers.
What are hailstones?
This is the amount of water vapor in the air.
What is humidity?
The parcels of air that are denser than the surrounding air do this.
What is sink?
These are located in our eye and detect multiple light inputs.
What are light sensors?
Kinetic energy is transferred from one particle to another in a particle ___________.
What is a collision?
Hailstorms are more common in this part of the United States.
What is the central United States?
This is the process by which, in a fluid being heated, the warmer part of the mass will rise and the cooler portions will sink.
What is convection?
When representing the molecules that made up the air in the closed bottle system after cooling down and after warming up, this is the number of dots should you draw.
What is the same amount of dots because it is a closed system?
The one way mirror phenomenon is strongest when this is true between the rooms.
What is a difference of light between the two rooms?
Temperatures change when energy moves from _______ to _______.
What is hot to cold?
This is what happens to the speed of molecules when the temperature of the air increase.
What is speeds up?
This is the type of cloud where hail is formed.
What is cumulonimbus?
This is how the density of helium in the balloon changes when thermal energy transfers into the balloon from the heating pad.
What is the density decreases because helium molecules move faster and spread out.
When light shines on an object, it can do these two things?
What is reflect and transmit?
A double-walled cup with a ______________ or air between the walls slows down the conduction of energy because there are fewer (or no) particles to collide between the walls.
What is a vacuum?
Changing the temperature of a parcel of air causes a change in the air's _________ due to changes in the kinetic energy and spacing of the molecules that make up the air.
What is density?
This unit is how the amount of light is measured.
What is lux?
This is how and why the density of the helium inside the balloon changed when thermal energy flowed out of the balloon into the surrounding air.
What is it became more dense because the gas molecules slowed down and were packed closer together.
