TEAS 7 - Science (Physical Properties of Matter) Flashcards
___ ___ is a property that depends on the amount of substance in a sample.
Extensive property
The characteristics that define matter are known as ___.
properties
Extensive property is property that depends on the ___ of substance in a sample.
amount
___ ___ is a property that does not depend on the amount of substance in a sample.
Intensive property
The characteristics that define matter are known as ___. These properties can be ___ or ___, which depends on whether the properties depend on the amount of matter or a substance.
properties
intensive
extensive
Physical properties of matter are any properties of matter that can be ___ or ___. Physical properties include elasticity, mass, volume, color, and temperature.
observed
measured
___ is a measure of the force that gravity exerts on an object.
Weight
___ properties of matter are any properties of matter that can be observed or measured.
Physical properties
There are a couple of ways to determine volume.
First, if the object is ___ shaped, you can multiply the length by the width by the object’s depth.
Second, if the object is ___ shaped you can measure the volume via ___ displacement (using a set amount of water and dropping the object into the water and measuring the difference in the volume of water).
regularly
irregularly
water
___ is a measure of the amount of substance within an object.
Mass
___ is a measure of the amount of space an object occupies.
Volume
___ is a measure of how fast molecules are moving in a substance. The more molecular movement, the ___ the temperature. It’s a measure of the internal energy of the substance.
Temperature
higher
___ is a measure of energy transfer – it’s the amount of energy transferred from one substance to another.
Heat
___ is the measure of the amount of mass per unit of volume. To determine the density of an object, you divide the mass of the object by the volume (D=m/v). It is expressed in terms of cubic unit (such as g/cm3 )
Density
The ___ ___ is the temperature and pressure at which a solid turns into a liquid (and vice versa).
Melting Point
The ___ ___ is the temperature and pressure at which a liquid turns into a gas (and vice versa).
Boiling Point
___ ___ ___ is the amount of heat needed to change the temperature of a unit mass of a substance by a certain unit of temperature.
Specific Heat Capacity
Extensive properties change as the ___ of a substance changes.
amount
Imagine you have a glass of water. If you were to double the amount of water, the volume of the water would also double.
Same with mass – doubling the amount of water would also double its mass
Thus, volume and mass are examples of ___ properties.
extensive
___ properties change as the amount of a substance changes.
Extensive properties
Length, mass, heat, and volume are examples of ___ properties.
extensive
___ ___ do not change as the amount of substance changes.
Intensive properties
Intensive properties do ___ change as the amount of substance changes.
not
Density, temperature, melting point, malleability, boiling point, specific heat capacity, and luster are examples of ___ properties.
