The CSDA range for protons in aluminum (in units of mass thickness g/cm2) are 2.953×10−4, 4.020×10−3, and 0.1692 for protons with energies of 0.1 MeV, 1 Mev, and 10 MeV, respectively [Janni 1982]. Use the empirical Eq. (7.47) to estimate these ranges and compute the percent difference. 21. Shultis, J. Kenneth; Faw, Richard E.. Fundamentals of Nuclear Science and Engineering (p. 220).

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

moisture is lackin, and organic acids are scarce.

if i am correct, your answer choices are:

a. the temperature remains constant

b. the temperature increases at a constant rate

c. heat flows at a constant rate into the system

d. heat flows at a constant rate out of the system

e. no heat flows into or out of the system

if so, then the answer is e. no heat flows into or out of the system.
