Referring only to Table 1.2 , answer the following questions: a . Devices are available that allow liquid volumes as small as one microliter ( μL ) to be measured. How many microliters would be contained in 1.00 liter ? b . Electrical power is often measured in kilowatts. How many watts would equal 75 kilowatts ? c . Ultrasound is sound of such high frequency that it cannot be heard. The frequency is measured in hertz (vibrations per second). How many hertz correspond to 15 megahertz ? d . A chlorine atom has a diameter of 200 picometers . How many meters is this diameter?

Consider the following Figure 2 and two atoms that are initially an infinite distance apart, x =00, at which point
the potential energy of the system is U = 0. If they are brought together to x = x, the potential energy is related
to the total force P by
dU
dx
= P
Given this, qualitatively sketch the variation of U with x. What happens at x=x? What is the significance of
x = x, in terms of the potential energy?

Figure 2. Variation with distance of the attractive, repulsive, and total forces between atoms. The
slope dP/dx at the equilibrium spacing xe is proportional to the elastic modulus E; the stress σb,
corresponding to the peak in total force, is the theoretical cohesive strength.
