What is the difference between the sensistor and thermistor?
Thermistor: Negative temperature coefficient Sensistor: Positive temperature coefficient.
When the temperature of ice cold water is increased slightly dpoes it undergo a net expansion or net contraction?
Contraction for a few degrees Celsius.

What si unit of linear co efficient?
You mean coefficient of linear expansion? Its unit is SI system is per kelvin Or practically speaking it may be given in per degree Celsius.
Does water expand in a tank that is heated?
For the most part, liquid water expands when heated, and so does pretty much every material. Water's volumetric expansion is a few hundred parts per million per degree Celsius. The interesting thing about water, though, is that if it's below 4°C it expands as it gets colder, i.e. it has a negative volumetric expansion coefficient.
An ordinary glass is filled to the brim with 350 mL of water at 100 C If the temperature decreased to 20C how much water could be added to the glass?
Difference in volume = (initial volume) (coefficient of volume expansion of water) (difference in temperature) coefficient of volume expansion of water=0.0002ml/degree celsius (not sure about the value. Better get help from a teacher.)
How is coefficient of thermal expansion measured?
Coefficient of Linear thermal expansion (CLTE) = Alpha Alpha=(change in length)/(original length*change in temp) =Meters/(meters*Celsius) =m/mC (meters cancel leaving...) =1/C =C^-1
How do you calculate coefficient of linear expansion of copper?
dL/dT = αL*L, where L is the length of the steel, T is temperature, and αL is the linear thermal expansion coefficient which for steel is about 11.0 to 13.0. That is possibly the easiest differential equation in history: (1/L)dL = (αL)dT ln(L) = αLT L = eαLT
What is Q-10?
temperature coefficient =10 degree celsius..
What is the units of temperature coefficient of resistance?
The unit of temperature coefficient of resistance is ohm per ohm per degree Celsius or say resistance per resistance per degree Celsius.
What is the temperature coefficient of resistance?
The temperature coefficient of resistance is a number used to predict how the resistance of a material changes with changes in temperature. Typically the units are either resistance per temperature or 1/temperature depending on which equation is used for the calculations. For example, in copper the temperature coefficient of resistance is about 0.0039 per change in degrees Celsius. A positive temperature coefficient of resistance means that the resistance of the material will increase as temperature increases. As per the equation or say unit of resistance temperature coefficient, its definition can be given as below: " Rise in temperature per unit initial resistance, when temperature is raised by one degree Celsius is called the resistance temperature coefficient."
