Cómo realizar un gráfico 2/3: papel semilogaritmico

Graphing with Semilogarithmic Paper

Introduction to Semilogarithmic Graphing

• The video continues with the second part of graphing, focusing on semilogarithmic paper using a dataset of temperature and pressure.

• Recap of semilogarithmic paper characteristics: constant scale on the x-axis while the y-axis has unequal intervals that decrease in size.

Understanding the Structure of Semilogarithmic Paper

• Explanation of cycles in semilogarithmic paper; it can have one, three, or even five cycles. The presenter uses a three-cycle paper for this demonstration.

Setting Up Axes for Graphing

• The x-axis will represent temperature ranging from 98.5°C to 215°C, while the y-axis will depict pressure from 1 mmHg to 100 mmHg.

• Each segment on the x-axis is set at an interval of 20°C, with specific temperature points identified (e.g., 98.5°C, 131.88°C).

Detailing Pressure Axis Configuration

• The y-axis is labeled as pressure in mmHg; two cycles are used: units (1 to 10) and tens (10 to 100).

• Units are marked from 1 to 10 in the first cycle; tens are marked from 10 up to 100 in increments of ten.

Plotting Data Points

• Identification and plotting of key data points for pressure: values include points like 1 mmHg, up to a maximum of 100 mmHg.

• Finalization involves locating pairs: e.g., at a temperature of 98.5°C corresponds to a pressure of 1 mmHg; other pairs follow suit leading up to higher temperatures and pressures.
