  • Waiting for answer How do you find the slope of the line normal to the curve ##...

    The normal line is perpendicular to the tangent line, meaning that it will have the opposite reciprocal slope of the tangent line. We use the derivative to give us the slope of the tangent line. 1) Find the derivative: The function ##(x^2+4)*y=8## is written implicitly. We could therefore use...

  • Waiting for answer How does vapor pressure related to intermolecular forces?

    Vapor pressure is the amount of gas in equilibrium with the liquid and solid phases. The higher the vapor pressure, the more gas in equilibrium, and thus the easier it is for the substance to vaporize (turn to gas), and vice versa. Intermolecular forces are the attractive interactions between mol...
