T_ P dependence of heat capacity
Heat capacity
Heat capacity
♦ Temperature dependence of heat capacity
• (C)(p) usually give as (C)(p)=(a)+(bT)+(cT)−(2)+(dT)(2)
• When phase changes → Heat capacity changes abruptly
♦ Pressure dependence of heat capacity
• (C)(p) of ideal gas
For ideal gas, (C)(p) is independence of pressure. Each molecule behaves independently.
• (C)(p) of solid
In most cases, (C)(p) is a function of temperature and not a function of pressure, but at high pressire, (C)(p) is strongly dependent on pressure.
