Physical versus Chemical Properties
I. Reviewing matter:
Matter: anything that has _______________ and takes up ______________
Is it Matter?
II. Property: a characteristic of a _________________ that can be _____________.
III. Physical property: a property that can be observed ________________ changing the _______________ of the substance. Examples: luster, ________________ (the ability to be hammered into ______________ _______________ ), __________________ (the ability to stretch into a _______________ ________________), melting point, _________________ point, density, solubility and specific heat.
IV. Special properties:
Melting point: temperature at which a substance changes from a solid to a __________ at a given
H2O = ________________ or _________________________
Boiling point: temperature at which a substance changes from a __________ to a _____________ at a given pressure.
H2O = ________________ or _______________________
V. Chemical property: a property that can be only be observed by _________________ the _________________ of the substance. Examples: flammability, ability to rust, reactivity with vinegar
Water’s density is ____________________.
VII. Calculations D = m/V = g/mL = g/cm3
Examples: A cube has a mass if 2.8g and occupies a volume of 3.67mL. Would this object float or sink in water? This object would _______________ in water because its density is _____________ than water whose density is ______________.
VIII. More Density Calculations
A liquid has a mass of 25.6 g and a volume of 31.6 mL.
What is the identity of the liquid? ______________________
