TYPES OF GAS heat.
The temperature of a gas can be increased in various conditions. Dikonstankan volume, the pressure dikonstankan or both can be changed according to the will-fox. In each of these conditions of heat required to raise the temperature of one unit for each unit mass temperature is different. In other words a gas has a variety of heat capacity. But only two kinds that have practical significance, namely:
- Heat capacity at constant volume.
- Heat capacity at constant pressure.
Ideal gas heat capacity at constant pressure is always greater than the ideal gas heat capacity at constant volume, and the difference of the general gas constant (universal), namely: R = 8.317 J / mole 0K.
cp - cv = R
cp = specific heat capacity (heat type) ideal gas at constant pressure.
cv = specific heat capacity (heat type) ideal gas at constant volume.
Based on the kinetic theory of gases we can calculate the specific heat of ideal gas, as follows:
a. For single beratom gas (monatomic) is obtained that:
b. For gas beratom two (diatomic) is obtained that:
= Constant of Laplace.
