materials is a database of physical and chemical data, possibly with temperature dependence, of various more or less common materials. All data are given in SI units.
For example, to plot the density of various materials between 274 and 370 K you can do
import materials
import matplotlib.pyplot as plt
import numpy
T = numpy.linspace(274.0, 370.0, num=100)
rho_air = materials.air.density(T)
rho_argon = materials.argon.density(T)
rho_copper = materials.copper.density(T)
rho_water = materials.water.density(T)
plt.semilogy(T, rho_copper, label='copper')
plt.semilogy(T, rho_water, label='water')
plt.semilogy(T, rho_argon, label='argon')
plt.semilogy(T, rho_air, label='air')
plt.title('densities')
plt.xlabel('temperature (K)')
plt.ylabel('density (kg/m^3)')
plt.legend()
plt.show()
materials is available from the Python Package Index, so simply type
pip install -U materials
to install or upgrade.
