Given data:
Diameter of the gold wire (d) = 0.175 cm
Length of the gold wire (l) = 1.00 * cm
Volume of the given gold wire = volume occupied by a cylindrical object\
= π * *l
here r = radius of the cross section
where : r = d/2
Hence the volume V = π * *l
=
Density of gold = 19.3 g/cm3
Weight of the gold wire = Density * volume
= *
=
The characteristics of the graphic representation are to find the scales and make the best graphic, in the attachment we have the points plotted
The graphical representation is one of the best methods to see the relationships between groups of data and to be able to find the functional relationships between them.
In this case, it is requested to make a scatter plot where the measured temperature is placed on the x-axis and the heat on the y-axis.
In the attachment we can see a graph with the requested data, the most important part of finding these graphs is looking for the scales
x-axis
scale x =
y-axis
scale y =
In general, the paper is 20 x 30 cm, we select the shortest part as the x axis
scale x =
scale x = 1º
Let's find the scale on the axis and the maximum value is 54000 and the minimum value is 3800, as the minimum value is much less than the maximum value, let's set this value to zero
scale y =
scale y = 1800
To facilitate marking the values, we select a slightly larger scale,
Selected scale
scale y = 2000 \frac{j}{cm \ paper}
Let's mark the points.
From observing these graph we see;
- The relationships are linear
- For the same material the amount of heat necessary to reach the same temperature is proportional to the mass of the material
Using the characteristics of the graphical representation, it is possible to find the scales and make the best graph
