|
BOILING POINT |
The boiling point of water is 100° Celsius. |
|
|
CELSIUS |
the scale of temperature in which water freezes at 0°C and boils at 100°C under standard conditions. |
|
|
FREEZING POINT |
the temperature at which a liquid turns into a solid when cooled. (WATER=0°C) |
|
|
MELTING POINT |
the temperature at which a given solid will melt. (WATER=0°C) |
|
|
TEMPERATURE |
is measured using a thermometer, in the Celsius scale in science. Our classroom is usually about 23 degrees Celsius. |
|
|
THERMOMETER |
an instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol that expands and contracts in the tube with heating and cooling. |
|
|
THERMAL ENERGY |
energy in the form of heat |
|
|
CHARACTERISTIC |
a distinguishing or identifying quality |
|
|
COMBUSTIBILITY |
capable of catching fire and burning |
|
|
CONDENSING |
change in matter from a gas to a liquid state |
|
|
ENERGY |
Energy is the capacity of a physical system to perform work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, electrical, or other forms. Energy can be changed from one form to another. |
|
|
EVAPORATING |
to change from a liquid or solid state into vapor |
|
|
HOMOGENEOUS |
a mixture is one that is uniform, and where the different components of the mixture cannot be seen |
|
|
MAGNETISM |
is a force of attraction or repulsion between materials that acts at a distance (through a magnetic field), and is ultimately due to the movement of electrons. Some objects are inherently magnetic, the most common example being iron magnets. |
|
|
MAINTAIN |
to cause (something) to exist or continue without changing |
|
|
RELATIVE DENSITY |
sink or float;
floats in water=less dense sinks in water=more dense |
|
|
STATES OF MATTER |
the three traditional states of matter are solids (fixed shape and volume) and liquids (fixed volume and shape by the container) and gases (filling the container) |
|
|
VAPOR |
Barely visible or cloudy diffused matter suspended in the air. |
|
|
VOLUME |
The amount of space an object takes up |
|
|
MOLECULE |
the smallest particle of a substance that retains all the properties of the substance |
