what happens to the conductivity of a substance if you increase the temperature of the solution....
what happens to the conductivity of a substance if you dilute a solution with water? Is the variation in concentration with conductivity a linear relationship? Explain.
The temperature of a substance does not change as the substance boils. Write two or three sentences to explain this at a molecular level.
How is vapor pressure related to temperature? What happens to the vapor pressure of a substance when the temperature is increased? Decreased? Check all that apply. The relationship between vapor pressure and temperature is not linear, but rather, it is exponential. The relationship between vapor pressure and temperature is linear. The vapor pressure of a liquid decreases with increasing temperature. The vapor pressure of a liquid increases with increasing temperature.
The temperature at the point (x, y, 2)in a substance with conductivity K - 7.5 is ux. 2) - 27 +22. Find the rate of heat flow inward across the cylindrical surface +2 -7,08x55. 840
In enzymes, what happens to the rate of reaction as the temperature increases? Explain in terms of how molecules collide and product conversion rates. What happens to the enzyme activity if you infinitely increase the temperature?

Argumentation and Documentation Classify each substance as metallic, ionic, molecular or covalent network based on your experimental results and further observations Part I. Testing Conductivity of Substances at Room Temperature Two substances were electrically conducting solids. The only classifications for substances that conduct electricity as solids are metallic or covalent network solids. Use the malleability property of metals to determine the classification of the two substances. Part II. Testing Conductivity of Solutions...
The temperature at the point (x, y, z) in a substance with conductivity K = 6.5 is u(x, y, z) = 2y^2 + 2z^2. Find the rate of heat flow inward across the cylindrical surface y^2 + z^2 = 5, 0 ≤ x ≤ 2
Explain
3. You have a material whose conductivity is being measured as temperature is decreasing. The conductivity is very low until you reach a certain temperature. At this temperature, the conductivity increased rapidly. What kind of material do you have? What is the temperature called at which the material starts to conduct?
At near room temperature, the electron conductivity of a metal decreases as the temperature is increases, while in a typical semiconductor, the electron conductivity increases as the temperature is raised. Can you explain why? Can you also predict that in an insulator, what is the trend of electron conductivity (Please be as brief as possible but clearly written)
Why as the temperature increases does the electrical conductivity decrease in metals but increase in electrolytes? Why do two circular current loops of the same size and with the same current direction attract each other when one is placed on top of the other but repel each other when they are placed side by side on the same plane? What happens in these two situations if the directions of current are opposite in the two loops? What are the similarities...
