10-4 Fill in the Blanks

In a higher temperature, particles move faster and BLANK with greater force and more frequently.

collide

The factors that increase a chemical reaction are a higher temperature, BLANK, and surface area.

concentration

In surface area, smaller pieces have more surface area so more BLANK is available for reactants to collide.

space

When water is heated on a stove, bubbles form and it shows that the water is changing BLANK, which is physical change.

state

The only proof of that a chemical change has occurred is the formation of a new BLANK.

substance

Signs of chemical changes include the formation of BLANK or a change in odor, color, or energy.

bubbles

A chemical property is the ability to BLANK and the ability to rust.

burn

A BLANK BLANK is a characteristic of matter that can be observed as it changes to a different type of matter.

chemical property

The substances that undergo a change no longer have the same properties because they no longer have the same BLANK.

identity

A chemical change is a change in BLANK in which the substances that make up the matter change into other substances with new physical and chemical properties.

matter

All BLANK can be described using both physical and chemical properties.

matter

In concentration, the amount of substances in a certain volume. Increase in concentration of at least one BLANK means that there are more particles available to bump each other and react.

reactant

A chemical property is the ability to burn and the ability to BLANK.

rot

A physical property is a solid, BLANK, heavy, rough, mass, volume, and density.
