Hi, need to submit a 500 words paper on the topic The Definition of Matter. Matter Matter is anything that has weight and occupies space and has mass. This is the alltimedefinition of matter. Mass on the other hand is the quantity that a substance possesses depending on the gravitational force acted on it when it is assigned a unit of weight. The formula is w=mg. even though sometimes the weight can vary, the mass of the body is always constant and can be measured by the resistance it portrays due to its change of position.
This property is oten referred to in relation to change of resistance of position or motion caled inertia. Because matter occupies space, mass of various subtances can be compared in relation to particular units of volume. This relationship is their density of the substance. Their mathematical formula is D=M/V
d = density
m = mass
v = volume
Matter exists in three states which are liquid, mass and gases. A solid depicts both a definite size and shape, liquid has definite volume but does not have a definite shape it takes the shape of the object that it is in and a gas on the other hand has neither a definite shape nor a definite volume and this is what defines the differences between these three. Matter undergoes changes that are either classified as chemical or physical.
In most cases, physical changes alters some aspects of its properties but the composition remains constant. For example liquid generally do not have a shape, but when it undergoes chemical changes, such as becoming an ice, it acquires a temporary shape. Activation energy is the necessrary energy required to accelerate the reaction of the chemial and physical changes that matter undergoes.
These reactions are either endothermic or exothermic because the heat raises the energy of the reactants for the burning to begin and the process takes place effectively. Dealing with desnisyt and specific gravity means that the focus is on the lightness or heainess of an object. The density of an object is defined by clculating its mass divided by its volume. This , which means that this is the mass in (g) divided by volume, which is (v) g/mL or g/cm3. The density of water is 1.0g/ML, gasoline and hydrocarbons have a density of 0.7g/ML, Aluminum has a density of 7.2g/ML and the “heaviest” substance metallic osmium weighs 22.5g/ML.
This is the reason as to why it is important to report and specify the materials and their respective density. According to the experiment that was carried out, 200g of hot tap water was poured into the beaker then measured as Tinitial
After a while, (7-10 small ice cubes) and place into the tube with warm water and swirled until the ice melted. The test tube was kept lower enough in the water for the ice to melt. After several hours record the temperature of the water, remove the test tube, and pour the melted ice into a graduated cylinder. The result should be recorded as V-ice and since the volume of water is 1.0g/mL
T-initial –T-final= the final density of water in this case
T i-Tf= D of the water after experiment
In this case, T i= 43ºC
And Tf=34ºC
 .The final density of water is therefore, 43ºC-34ºC= 9ºC
