## Surface Tension of Pure Water Solution

STEP 0: Pre-Calculation Summary
Formula Used
surface_tension_of_pure_water = 235.8*(1-(Temperature/Critical Temperature))^(1.256)*(1-(0.625*(1-(Temperature/Critical Temperature))))
γw = 235.8*(1-(T/Tc))^(1.256)*(1-(0.625*(1-(T/Tc))))
This formula uses 2 Variables
Variables Used
Temperature - Temperature is the degree or intensity of heat present in a substance or object. (Measured in Kelvin)
Critical Temperature - Critical Temperature is the highest temperature at which the substance can exist as a liquid. At this phase boundaries vanish, and the substance can exist both as a liquid and vapor. (Measured in Kelvin)
STEP 1: Convert Input(s) to Base Unit
Temperature: 85 Kelvin --> 85 Kelvin No Conversion Required
Critical Temperature: 647 Kelvin --> 647 Kelvin No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
γw = 235.8*(1-(T/Tc))^(1.256)*(1-(0.625*(1-(T/Tc)))) --> 235.8*(1-(85/647))^(1.256)*(1-(0.625*(1-(85/647))))
Evaluating ... ...
γw = 90.3103050470597
STEP 3: Convert Result to Output's Unit
90.3103050470597 Newton per Meter -->90310.3050470597 Millinewton per Meter (Check conversion here)

## What are the effect of temperature on surface tension?

Surface tension decreases with an increase in temperature. So these are the effects of temperature on surface tension. In general, surface tension decreases when the temperature increases because cohesive forces decrease with increased molecular thermal activity.
