Waves
A disturbance that transfers energy without transferring matter.
What is a wave?
The electromagnetic spectrum is a term for this kind of energy.
What is light?
This measures the amount of stuff in something
What is mass?
Making a mixture is an example of this kind of change.
What is physical?
An example of this kind of change is dissolving cereal in water
What is a physical change?
The matter a wave travels through is called a medium, and this kind of wave cannot travel without it.
What is a mechanical wave?
A laser beam which enters a glass of water and travels at a different speed is distorted through this process.
What is refraction?
This measures how big an object looks and how much room it needs.
What is volume?
This heterogenous mixture is easy to separate and settles out over time
What is a suspension?
The number of carbon atoms in CO2
What is one?
Sound waves are mechanical waves which require this to travel.
What is a medium?
This is the order of the colors of the rainbow from lowest energy to highest energy.
What is red orange yellow green blue indigo violet?
This measures compactness, and things with more of it sink.
What is density?
A solution has a solute dissolved in solvent. It is this kind of mixture.
What is homogeneous?
Production of either of these two things is a clue that a chemical reaction has occurred.
What is a gas? or What is a precipitate?
Another chance if answer “What is a new substance”
As wavelength increases, frequency does this.
What is decreases?
A wave with a longer wavelength than gamma radiation would have this much energy in relation to it.
What is less energy?
A substance with a mass of 4 grams and a volume of 6 milliliters has this density.
What is 0.67 g/mL
Blood and milk, which look evenly mixed but can be separated by special techniques, are examples of this kind of mixture.
What is a colloid?
Chemical reactions cannot change thid property.
What is mass?
Sound travels most quickly through this medium, and its energy is absorbed most quickly by this same medium.
What is a solid?
Infrared waves have a lower frequency and a longer wavelength than visible light. Infrared waves travel at this speed compared to visible light when in a vacuum.
What is the same speed?
While used to measure mass, this physical property depends on gravity and changes when gravity changes.
What is weight?
In a solution, a solute is the thing dissolved and this is the thing doing the dissolving.
What is the solvent?
This measures acidity, and is lower for acids than for bases.
What is pH?
