Give two examples of thermal insulators
Plastic and wood
Distillation: It is used to separate two liquids (T/F)
True
Heterogeneous: we can not see the separate substances (T/F)
False
Is salt soluble?
Yes
Mass is the amount of space that matter occupies (T/F)
False
Hot chocolate: heterogeneous or homogeneous
Homogeneous
Volume is the amount of matter in an object (T/F)
False
Name the four chemical changes
Rotting, rusting, burning and fermentation
Name the two changes in matter
Physical changes and chemical changes
Which are the main ways to separate mixtures?
Filtration, evaporation and distillation
Evaporation: It is used to separate an insoluble solid from an heterogeneous mixture (T/F)
False
Materials that don't dissolve are...
Insoluble
Density is the amount of volume that there is in the mass of an object (T/F)
False
Is shape a physical change?
Yes
Is place a chemical change?
No
In chemical changes the composition change, so new matter is formed and these changes can't be reversed (T/F)
True

Gas, liquid and solid
Materials that dissolve are
Soluble
Pepper in water is insoluble?
Yes
Which are the properties of matter?
