19M.1A.SL.TZ1.11

An insulated tube is filled with a large number n of lead spheres, each of mass m. The tube is inverted s times so that the spheres completely fall through an average distance L each time. The temperature of the spheres is measured before and after the inversions and the resultant change in temperature is ΔT.

What is the specific heat capacity of lead?

A. $\frac{{sgL}}{{nm\Delta T}}$

B. $\frac{{sgL}}{{\Delta T}}$

C. $\frac{{sgL}}{{n\Delta T}}$

D. $\frac{{gL}}{{m\Delta T}}$
