It's All In Your Properties
This type of property depends on the amount of substance present.
What is an extensive property?
The simplest form of matter that cannot be broken down chemically.
What is an element?
On a heating curve, a flat line represents this happening to the substance.
What is a phase change?
Tearing paper is this type of change.
What is physical change?
The formula for density is this.
What is mass divided by volume?
Density is this type of property.
What is intensive property?
Water (H2O) is an example of this type of pure substance.
What is a compound?
The phase change at 0°C for water is from this state to this state.
What is solid to liquid (melting)?
Burning wood is this type of change.
What is a chemical change?
A cube has a mass of 48.7 g and each side is 2.00 cm long. What is its density?
What is 6.09 g/cm3?
Mass and volume are examples of this kind of property.
What are extensive properties?
Saltwater is an example of this type of mixture.
What is a homogenous mixture?
On a heating curve, the diagonal sloped lines represent this.
What is a temperature increase within one phase?
Rust forming on iron is this type of change.
What is a chemical change?
An irregular object is dropped in a graduated cylinder. The water level rises from 25.0 mL to 32.6 mL. If the object’s mass is 19.8 g, what is its density?
What is 2.61 g/mL?
This type of property describes how a substance reacts with other substances.
What is a chemical property?
A salad is an example of this type of mixture.
What is a heterogenous mixture?
The temperature stays constant during melting because energy is used to break these.
What are intermolecular forces?
Boiling water is this type of change.
What is a physical change?
A sample of aluminum has a mass of 13.05 g and a measured density of 2.71 g/cm3. Calculate its volume.
What is 4.82 cm3?
Flammability, reactivity, and toxicity are all examples of these properties.
What are chemical properties?
Brass (an alloy of copper and zinc) is considered this type of mixture.
What is a homogenous mixture?
Labeling a heat curve: this is the point where liquid water turns into steam at 100°C.
What is vaporization/boiling?
The best way to tell if a chemical change has occurred is if this has formed.
What is a new substance?
A rectangular solid has dimensions 4.20 cm × 3.10 cm × 2.55 cm and a mass of 102.5 g. What is its density?
What is 3.09 g/cm3?
