A negative temperature coefficient indicates that the dependent variable, the variable of interest increases when the temperature decreases and conversely. This could, for example, be the density of an object (excluding water at 0 - 4 deg C). As the temperature goes up the volume increases so the density decreases.

What is cofficient in term 5x?
5x 5 is the coefficient and x is the variable.
How do you use negative and positive numbers in everyday?
negative numbers> temperature.
Does the cofficient of linear expansion depend on length?
No, it is a fundamental mechanical property of the material
Can an angle be negative in trigonometry?
no because the only way degrees can be negative is in temperature.
What is the meaning of the algebra term cofficient?
In the equation 2x = 6 the coefficent of x is 2
What is temperature cofficient in pn junction?
Temperature coefficient of the PN intersection voltage to balance the temperature coefficient of the warm voltage.
How the resistance of conducting material vary with temperature?
Well, there's typically two types of materials-Those with positive temperature coefficient and those with negative temperature coefficient. Positive temperature coefficient are those whose resistance increases as temperature increases. Negative temperature cofficient are those whose resistance decrease when the temperature increase. There are however some alloys such as Manganin& Constantan whose resistance is not affected by temperature
Properties of correlation cofficient?
why correlation cofficient always lies between 1 and -1
What is the 5 in 5n called?
That 5 is the cofficient of the term. The "n" is the variable!
Why are alloys constantan and Manganin used to make standard resistors?
They are used to make standard resistors because 1)they have high value of resistivity.2)temperature cofficient of resistance is less.3)they are least affected by temperature.
What is the difference between hall-effect in metals and semiconductor?
because we have hall cofficient =1/ne. where the n=no of electron ,e=charge of electron. we know that "n "in metal is very large. so that R=HALL COFFICIENT" is very small FOR it .so we can not find sufficient result for hall cofficient so we use semi conductor which gives non zero hall cofficient.
What is Cofficient of restitution of a perfectly plastic impact?
e=0
Does a safe reactor have a positive or negative 'temperature coefficient of reactivity'?
negative 'temperature coefficient of reactivity'
What is cofficient in term 5x?
5x 5 is the coefficient and x is the variable.
What temperature is lower negative 3 or negative 5?
-5 is lower
How do you use negative and positive numbers in everyday?
negative numbers> temperature.
What is the co efficient for window grill painting?
cofficient of window 1mx1m
