The Arhennius viscosity model describes how viscosity u depends on temperature 1:
u = uo e E/RT
1 DVD DVD
Here u is viscosity (Pa.s), I is the temperature (in "Kelvin), E is the activation energy (J mol¹), R is the universal gas constant (R = 8.3145 J mol¹¹ K¹) and
U is a constant (Pa s).
Ensure all your numerical answers are provided, accurate to 4 significant figures.

- Verify the normalization equation 0f(v)dv=1 In doing the integral, first make substitution u=m2kBTv=vvp. This "scaling" transformation gives you all features of the answer except for the integral, which is a dimensionless numerical factor. You'll need the formula 0x2e x 2dx= 4 to find the numerical factor and verify the normalization.`arrow_forwardIn solid, atoms are spaced closer than in liquid, as shown in Figure 2. Density of a substance is defined as its mass per unit volume. Therefore, density of a solid is typically greater than the density of liquid.
