Plasma blood glucose level is measured after a period of fasting, typically at least 8 hours. The specific heats of an ideal gas are represented by C P and C V. This is the amount of heat required to raise the temperature of unit mass by 1 C. By the first law of thermodynamics, Q = U + W where, Q is the amount of heat that is given to the system, U is the change in internal energy, and W is the work done. The change in temperature = T = T2 - T1 = 80 - 40 = 400c. The SI unit of heat capacity is joule per Kelvin (J/K). Where Q cal is the energy absorbed, C is the constant and T is the same as the change in temperature of the water. To understand the relationship between thermochemistry and nutrition.
