### Question Description

Help me do Lab 3: Thermal Expansion.

4 Data Analysis 1. Derive a symbolic expression for the uncertainty in the expansion coefficient (δα) using the partial derivative method (Equation 2). • Your expression should be in terms of the following quantities: L, ∆L, ∆T, δL, δ(∆T), δ(∆L). 2. To determine the temperature values that correspond with the measured resistance values, assume the relationship between between R and T is linear (this is a good assumption only over small temperature ranges), and interpolate between the adjacent data points. • The uncertainty stated by Pasco for the thermistor values is ±0.2 ◦C. • Assume 3 sigfigs for given temperature values. For example, assume the temperature value listed as 25◦C is actually 25.0 ◦C 3. Calculate ∆T ± δ(∆T). Recall that the uncertainty in a sum or difference is given by Equation 3 in the introduction. 4. Use Equation 1 to find α. 5. Use the expression derived in step 1 of the data analysis instructions to find δα. 6. Compare with the theoretical α value.
