LAB 5 – Thermal Physics 1. Thermal Expansion A. Copper (for example) Initial Temperature, [please get the reading in Multi-meter and use calibration factor to convert it into ] Initial Length, Final Temperature, [similar like above] Elongation, Use the formula for thermal expansion, Also use the formula to find the error, B. For Aluminum/Steel [Do similarly] 2. Charles’ Law We know the volume of a cylinder is, . As during this process, only height is changing, therefore, we can conclude that Therefore we can write the relation of Charles’ Law for this experiment as follows: where is a proportionality constant.

Unformatted text preview: If the dependence between the height h of the cylinder and the temperature T is linear, then the Charles’ Law is verified. Table 1: The dependence of the height of the cylinder versus the temperature of the air T ( o C) h (mm) 1. ? ? 2. ? ? 3. ? ? 4. ? ? 5. ? ? Figure 1: Charles’ Law Height ( h ) versus Temperature ( T ). 3. Heat Engine The area of the piston: At = 0 o C; At = 0 o C At = 100 o C At = 100 o C Figure 2: Pressure-volume diagram for the heat engine gauge pressure versus volume. =?
