A beam of aluminum is 5.000 meters long at 20°C. By how many millimeters does its length increase if the temperature is raised to 50°C? If the cross-sectional area of the beam is 10 cm by 20 cm, by how many cm3 does its volume increase when the temperature is raised from 20°C to 50C°?
[30 Marks] Q 1(b) When comparing column performance between a capillary and a packed GC column, one is struck by how similar the plate height is on the two columns. And yet as shown in Table 1, we see that we get almost 10x better resolution on the capillary column Discuss why this difference in resolution arises, in terms of the van Deemter equation Tabie 1 Comparison of packed and wall coated open tubuiar column performance Open Tubular Packed 0.73...
