Introduction
In chemistry, understanding the relationship between volume and temperature is crucial in various applications, including thermodynamics and gas laws. One of the fundamental principles in this context is the ideal gas law, which relates the volume of a gas to its temperature, pressure, and amount of substance. In this article, we will focus on finding the ratio of the volume divided by the temperature for the first data pair, using significant figures.
The Ideal Gas Law
The ideal gas law is given by the equation:
PV = nRT
where P is the pressure, V is the volume, n is the amount of substance, R is the gas constant, and T is the temperature in Kelvin.
Calculating the Ratio of Volume to Temperature
Given the data pair:
V = 0.72 T = 276
We are asked to find the ratio of the volume divided by the temperature, i.e., V/T.
Using Significant Figures
Significant figures are a way of expressing the precision of a measurement. In this case, we have two measurements: V = 0.72 and T = 276. To find the ratio V/T, we need to follow the rules of significant figures.
Calculating the Ratio
To calculate the ratio V/T, we simply divide the volume by the temperature:
V/T = 0.72 / 276
Performing the Division
To perform the division, we can use long division or a calculator. Let's use a calculator to find the result:
V/T = 0.72 / 276 ≈ 0.0026
Rounding to Significant Figures
Now that we have the result, we need to round it to the correct number of significant figures. Since the original measurements had 3 significant figures, we will round the result to 3 significant figures:
V/T ≈ 0.0026
Conclusion
In this article, we have found the ratio of the volume divided by the temperature for the first data pair, using significant figures. We have used the ideal gas law and followed the rules of significant figures to ensure the accuracy of our result. The ratio V/T is approximately 0.0026, rounded to 3 significant figures.
