The amount of heat (g) gained or lost by a substance (with mass m) as its temperature changes (AT) depends on its specific heat capacity (C,) according to the following equation. q - C, xm x AT The quality of industrial diamonds is determined in part by measuring the specific heat capacity, which is 0.5091 /g-K for pure diamond. If the absorption of 26.06 ) of heat by a 2.10g diamond sample of unknown purity causes its temperature to rise from 25.90°C to 73.45°C, is the diamond sample pure? Explain your reasoning. The calculated C, is J/g-K and the value for pure diamond is 0.5091 J/g-K. These values are --Select- , thus the sample ---Select- pure. Need Help?

Human Movement

Humans can move from one place to another through coordinated movements and postures. The movement produced by the human body due to the contraction of muscles and bending of bone joints is called human movement. Human movements are controlled by the nervous system. Hence, the human movement incorporates the use of muscles, ligaments, joints, and bones.  Kinesiology is the field that deals with the study of human movements.
