Change in temperature equation
WebOct 4, 2024 · Specific Heat Equation and Definition . First, let's review what specific heat is and the equation you'll use to find it. Specific heat is defined as the amount of heat per unit mass needed to increase the … WebThe resistance-change factor per degree Celsius of temperature change is called the temperature coefficient of resistance. This factor is represented by the Greek lower-case letter “alpha” (α). A positive coefficient for a material means that its resistance increases with an increase in temperature. Pure metals typically have positive ...
