1) One of Dr. G’s CHEM 102 students is working part-time at a hardware store. A customer tells this student “I need a single stud (a wooden beam) from which I can cut two (2) pieces of 2.7m studs”. The student does the math, goes behind counter, and brings a stud cut to 5m length. Select the most sensible and scientific answer to this situation. A) 2.7 × 2 when operated as a significant figure multiplication, gets you 5 and the student is right. B) Hardware stores don’t comply with correct sig. fig. rules for measurements. C) The customer must pay for 5.4m worth; but he/she should only get 5m to take home. D) The word ‘Two (2)’ mentioned here carries infinite significance, so the student is wrong. E) The word ‘Two (2)’ mentioned here is not a ‘measurement’, therefore this is an example of a situation where there is disagreement between science and day-to-day life.
A 25 mL pipet delivers 24.7761 g H2O which is weighed against brass weights at 25°C. Calculate the volume delivered at 25°C and at 20°C.

A customer has ordered the airplane but requested that its total weight be reduced by 10 percent for fuel saving purposes. An engineer in the design and analysis department has suggested that the weight saving objective can be accomplished by replacing the current aluminum alloy of the floor beams with another one containing 3 wt% Li and 1 wt% Cu. Is this possible? Answer the question by first determining the weight saving that will take place using the Al-Li alloy. Assume weighted averages of density and use the following densities for the mentioned materials: Al = 2.70 g/cm³ Cu = 8.92 g/cm³ Mg = 1.74 g/cm³ Li = 0.53 g/cm³arrow_forwardA specimen of a 4340 steel alloy having a plane strain fracture toughness of 45 MPa sqrt(m) (41 ksi sqrt(in)) is exposed to a stress of 1000 MPa (145,000 psi).

Measure the temperature (θR) of the room. Transfer a known volume (V1) of warm water into the cup that can fill it to about two thirds of its capacity. Keeping the cup open, stir the warm water continuously until its temperature falls down to a value θ1 that is about 5 or 60C above θR. Dry some small blocks of ice with a clean rag and drop them into the warm water. Place the wooden or cardboard lid over the cup, with the stirrer and the thermometer in the holes in it.
