ANALYSIS: After following the specific procedures listed on our manuals and recording and computing for every necessary data, we have we have come up with this table. We used the formula formula:
(thot-trm) for the change in temperature of the tube and this the computation of the experimental coefficient of
ΔL= Lo α Δtfor
linear expansion. The other values where just measured and recorded directly. Table 301:

Here is a picture of our group listing the data that we have gathered in the experiment
Like what the theory in Linear Expansion states that generally, all materials expand when the temperature rises and shrinks as the temperature decreases. The increase or decrease can occur to the length, area, and volume but since this experiment focuses on the one dimensional change, only the length dimension of the solid tubes is observed. Using the steam generated, we increased the temperature of the tubes until it reached a point where its temperature is stable. As you can see in the table 301 both of the tubes showed an increase in length after increasing its temperature. This is the picture of the steam generator giving of heat to the copper tube. We used a rubber tubing to connect the steam it generates toboth aluminum and copper tubes.
We used the formulaΔL= Lo α Δtto compute for the coefficient of linear expansion, where Lo is the initial length, Δt is the change in
