Given that the apparent cubic expansivity of a liguid is 0.0001510-3k_7 and the linear expansivity of the container is 0.0001210_3k_1.calculate the real expansivity
To calculate the real expansivity, we need to use the formula for apparent expansivity and linear expansivity.
The formula for the real expansivity is given by:
Real expansivity = Apparent expansivity - Linear expansivity
Given:
Apparent cubic expansivity of the liquid (k_7) = 0.0001510^(-3) K^(-1)
Linear expansivity of the container (k_1) = 0.0001210^(-3) K^(-1)
Let's substitute the given values into the formula:
Real expansivity = 0.0001510^(-3) K^(-1) - 0.0001210^(-3) K^(-1)
Now, let's simplify the expression:
Real expansivity = 0.0001510^(-3) - 0.0001210^(-3) K^(-1)
Calculating the values:
Real expansivity = 1.337063623 K^(-1) - 8.26446281 K^(-1)
Real expansivity = -6.927399187 K^(-1)
Therefore, the real expansivity is -6.927399187 K^(-1).
