Matter is anything that takes up space and has mass.
solid, liquid, and gas.
What are the two types of mixtures?
Heterogeneous and homogeneous mixtures.
Is Ripping up a piece of paper an example of a physical change or a chemical change?
Ripping paper is a physical change.
Mass measures:
a. how heavy something is
b. how big something is
Mass is a.) how heavy something is.
Mass is the quantity of matter an object has.
When solid changes into a liquid, such as ice melting into water, we call this: ___________.
Melting.
Give 1 example of a pure substance and 1 example of a mixture.
Pure substance is anything with only 1 component, a mixture is anything with 2 components.
Matter is transformed into a new substance is which -- a physical or a chemical change?
Matter is transformed into a new substance during a chemical change.
Do we use kilograms (kg) and grams (g) to measure mass or volume?
We measure mass in kilograms (kg) and grams (g).
When a liquid changes into a solid, like water freezing at 0 degrees C, we call this: ___________.
Name 3 different ways we can separate mixtures.
Filtration, evaporation, decantation, or distillation.
Chemical changes are also known as _______ __________.
Chemical changes are also known as chemical reactions.
What has more volume -- 10 millilitres of water or 1 litre of water?
1 litre of water is way bigger than 10 millilitres!
When a liquid changes to a gas, like when water is heated at 100 degrees C, we call this: __________.
Evaporation.
Like boiling a pot of water.
Which method do we use to separate a liquid from a solid?
Either filtration or evaporation.
In a physical change, the form or shape changes.
Which of the following are not made up of matter?
Wood, light, sound, water, fabric.
Light and sound are not matter.
When gas turns into a liquid, like the steam in the shower, we call this: ___________.
Condensation.
Which method is used for homogeneous mixtures of two liquids?
Distillation is used for homogeneous mixtures of two liquids with different boiling points.
True or false:
In chemical reactions, the total amount of mass never changes because the total mass of reactants is the same as the total mass of products.
true.
Matter is never created or destroyed -- just transformed into new things!
