States of Matter
This state of matter will take the shape of its container.
What is a liquid?
Bigger part of the solution
What is an solvent?
This changes the phase of matter.
What is heat?
Smaller part of a solution. Give an example.
What is a solute? Example, sugar, salt, etc.
A process in which solid change into liquid. Explain the role of the heat.
What melting? heat is added.
When a substance dissolves in another substance it is called this.
What is a solution?
Compare soluble and insoluble. Give an example.
Soluble is completely dissolved, example sugar.
Insoluble cannot be dissolved, example rock.
A box measures 10 cm long, 4 cm wide, and 2 cm high. What is the volume?
V=l×w×h=10×4×2=80cm3
A process in which Gas change to liquid.
What is condensation?
A mixture in which solid particles are dispersed in a liquid or gas but are not dissolved. The particles are large enough to be seen and can settle to the bottom over time if left undisturbed
What is suspension?
This compound is usually used as solvent.
What is H2O?
A liquid occupies a volume of 250 mL and has a density of 0.8 g/mL. What is its mass?
m=V×d=250mL×0.8g/mL=200g
A process in which solid change to gas. Give one example.
What is a sublimation. dry ice
This is the metric measurement for volume.
What is liter (L)?
The particles are held together firmly. There is very little movement of particles. Give one example
What is a solid? Eraser, box, and many others
Give one example of colloid.
What are milk, yougurt, and many others.?
A piece of copper has a mass of 1,200 g and a volume of 150 cm³. What is its density?
d=Vm=150cm31200g=8g/cm3
Describe the movement of particles when the temperature and pressure change.
Particles move faster when the temperature and pressure go higher.
This is the metric unit of measure for mass.
What is gram (g)?
