Entropy

Consider a real gas, which obeys the following equation-of-state: v = RT/P + C1 - C2/(Pv), where v is the mass specific volume, P is the pressure, T is the temperature and R is the...

M kg of a liquid at a temperature T₁ is mixed with M kg of the same liquid at another temperature T₂ in an isolated tank at constant pressure. The mass specific heat capacity at co...

A rigid spherical solid ball at 1000 °C is cooled slowly to 200 °C in a surrounding air at 25 °C. The density, specific heat capacity, and diameter of the ball are 8000 kg/m³, 500...
