The relationships among the volume of a gas and its pressure, temperature, and amount are summarized in Figure \(\PageIndex{5}\). Volume increases with increasing temperature or amount but decreases with increasing pressure. Figure \(\PageIndex{5}\): The Empirically Determined Relationships among Pressure, Volume, Temperature, and Amount of a Gas.

Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other. Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, and more.
Standard - Compare and understand the relationship between different temperatures. Included Skills: Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge ...
28 Μαΐ 2020 · Answer. Pressure is defined as force per unit area. Similarly to the example in the text of the elephant and the figure skater, the more wheels or axles on the vehicle, the more area the weight is spread over, causing less pressure to be exerted on any one point on the bridge.
These examples of the effect of temperature on the volume of a given amount of a confined gas at constant pressure are true in general: The volume increases as the temperature increases, and decreases as the temperature decreases.
The mathematical forms of Gay-Lussac’s law are the following. \[P\propto{T}\nonumber\], or \[P=\mathrm{k}T\nonumber\], or \[\frac{P}{T}=\mathrm{k}, \nonumber\] where \(k\) is a constant, \(P\) is pressure, and \(T\) is the temperature (in kelvin scale) of the gas. Since Since \(\frac{P}{T}\) is a constant, it implies that
Pressure Law Example: Using the example of the sealed cylinder above the pressure of gas is recorded as 1.0 x 10 5 N/m 2 at a temperature of 0°C. The cylinder is heated further till the thermometer records 150°C.
