The density of steel at different temperatures can be calculated using the following formula:
ρt = ρ20 [1 + αt (t - 20)]
Where:
ρt = density of steel at the given temperature (in kg/m^3)
ρ20 = density of steel at 20℃ (in kg/m^3)
αt = coefficient of thermal expansion of steel (in 1/℃)
t = given temperature (in ℃)
The coefficient of thermal expansion of steel is approximately 1.2 × 10^-5 1/℃.
Using the above formula, we can find the density of steel at 100℃.
ρ100 = 4800 [1 + 1.2 × 10^-5 (100 - 20)]
ρ100 = 4986.4 kg/m^3
Therefore, the density of steel at 100℃ is 4986.4 kg/m^3.
The density of steel is 4800kg/m^3 at 20℃. Find the density at 100℃
