Why does the resistance of a thermistor decrease as the temperature rises?
Some materials have negative temperature coefficients of resistance, and some have positive temperature coefficients. Carbon is an example of a substance with a negative thermal coefficient of resistance, so it's resistance will decrease as it gets hotter.

Could you have a quadratic function with one real root and one complex root?
Provided some of the coefficients and the constant were imaginary (complex) as well, yes. For example, (x + 2)(x - 3+i) has both a real and an imaginary root, and has coefficients that are also both real and imaginary, i.e. 1, -1+i, and -6+2i.

What information is needed to calculate the equilibrium constant of a reaction?
To calculate the equilibrium constant (K) of a reaction, you need the concentrations or partial pressures of the reactants and products at equilibrium. Specifically, you need to know the balanced chemical equation for the reaction, as K is derived from the ratio of the products' concentrations raised to the power of their coefficients, divided by the reactants' concentrations raised to the power of their coefficients. Additionally, temperature is essential, as the equilibrium constant is temperature-dependent.
What is a constant value that are not coefficients of variables to equations?
parameters
What are the common characteristic between simultaneous linear equations in 2 unknowns which have no solutions?
The coefficients and constant in one of the equations are a multiple of the corresponding coefficients and constant in the other equation.
What are the units of equilibrium constant Kc?
The units of equilibrium constant Kc are mol/Ln, where n is the sum of the stoichiometric coefficients of the products minus the sum of the stoichiometric coefficients of the reactants in the balanced chemical equation.
Why do materials have different coefficient of friction?
Different materials have different coefficients of friction because the materials have different microscopic bumps and valleys which cause the friction to begin with. Coefficients of friction are constant for each material.
How is the equalibrium constant of a reaction determined?
The equilibrium constant (K) of a reaction is determined by measuring the concentrations of the reactants and products at equilibrium. It is calculated using the formula K = [products]^(coefficients) / [reactants]^(coefficients), where the square brackets denote the molar concentrations of the substances involved. This value is specific to a particular reaction at a given temperature and indicates the ratio of product concentrations to reactant concentrations when the reaction has reached equilibrium.
What has the author Harry Emmett Gunning written?
Harry Emmett Gunning has written: 'The temperature coefficients of the conductances of certain alkali halides' 'Temperature coefficients of the conductances of potassium chloride solutions'
As the temperature increases materials with large coefficients of linear expansion increase a lot in size while materials with small coefficients of linear expansion increase a in size?

How can one determine the equilibrium constant for a chemical reaction?
To determine the equilibrium constant for a chemical reaction, you can measure the concentrations of the reactants and products at equilibrium and use these values in the equilibrium expression. The equilibrium constant (K) is calculated by dividing the concentration of the products raised to their stoichiometric coefficients by the concentration of the reactants raised to their stoichiometric coefficients.
Do all temperature transducers have positive temperature coefficients?
A: YES but some the output could go negative as temperature changes
When you write an equilibrium constant expression how do you decide what goes on in the numerator and in the denominator?
In an equilibrium constant expression, the numerator consists of the concentrations (or partial pressures) of the products raised to the power of their stoichiometric coefficients from the balanced chemical equation. Conversely, the denominator contains the concentrations (or partial pressures) of the reactants, also raised to the power of their respective stoichiometric coefficients. This arrangement reflects the principle of the law of mass action, which states that at equilibrium, the ratio of product concentrations to reactant concentrations remains constant at a given temperature.
What is the equilibrium constant for the reaction SO (g) No (g) SO (g) no (g)?
The equilibrium constant (K) for a reaction is defined by the concentrations of the products raised to their stoichiometric coefficients divided by the concentrations of the reactants raised to their stoichiometric coefficients at equilibrium. However, the reaction you've provided appears to be incorrectly formatted or incomplete, as it lists "SO" and "No" without clear stoichiometric coefficients. Please clarify the reaction for a more accurate determination of the equilibrium constant.
