is the study of the transformations that matter is able to undergo, together with the energy changes associated with these changes.
physical changes in that it is made up of two or more substances that are combined physically, homogeneous and heterogeneous
mixture of two or more substances, in which you can not see distinguishable parts in the mixture.
mixture of two or more substances, in which you can see distinct parts in the mixture.
Matter that has the same chemical composition throughout and cannot be separated into its parts by physical means.
a process used to separate dissolved solids from a liquid, which is boiled to produce a vapor that is then condensed into a liquid
A technique that is used to separate the components of a mixture based on the tendency of each component to travel or be drawn across the surface of another material.
a type of error: the measurement is consistently off in the same direction always too high or too low.
Gravitational potential energy
mgh... g=9.8m/s2. m is the mass of the object in kg, and h is the height in meters.
5.6 kg x 9.8 m/sec2 x 6.1m =335J
Bowling Ball weighs 5.6kg, falling 6.1m out a window. what is its energy in J?
Specific Heat Capacity
the amount of heat energy required to raise the temperature of one gram of substance by one degree celcius
J = (g)(c)(ΔT)..... g= mass; c= specific heat capacity (J/g-°C); ΔT= the change in temperature. what the water change was.
a change that occurs when one or more substances change into entirely new substances with different properties
Total Disorder; Has much empty space, particles have complete freedom of motion, particles are far apart.
Disorder: partilces or clusters of particles are free to move relative to the other particles, particles are close together.
