What are all the important formulas for the chapter Thermodynamics?

Answer 1

Formulaes are in the following:

1) #C_p-C_v=R# 2) #DeltaQ=DeltaW+DeltaU# 3) In Isothermal process, #PV=constant# In Adiabatic process, #PV^gamma=constant# 4) Thermal efficiency#(eta)=W/Q_1=1-Q_2/Q_1# These are the main formulaes used in Thermodynamics.

Some important formulas for the chapter Thermodynamics include:

  1. First Law of Thermodynamics: [ \Delta U = Q - W ] where: ( \Delta U ) is the change in internal energy, ( Q ) is the heat added to the system, and ( W ) is the work done by the system.

  2. Work done by gas (Isothermal): [ W = -P \Delta V ]

  3. Work done by gas (Adiabatic): [ W = \frac{{P_1V_1 - P_2V_2}}{{\gamma - 1}} ] where: ( P_1 ) and ( P_2 ) are the initial and final pressures, respectively, ( V_1 ) and ( V_2 ) are the initial and final volumes, respectively, and ( \gamma ) is the ratio of specific heats.

  4. Heat transferred during a phase change: [ Q = mL ] where: ( Q ) is the heat transferred, ( m ) is the mass, and ( L ) is the latent heat of the substance.

  5. Ideal Gas Law: [ PV = nRT ] where: ( P ) is the pressure, ( V ) is the volume, ( n ) is the number of moles, ( R ) is the ideal gas constant, and ( T ) is the temperature in Kelvin.

  6. Entropy change in a reversible process: [ \Delta S = \frac{Q}{T} ] where: ( \Delta S ) is the change in entropy, ( Q ) is the heat added to the system, and ( T ) is the temperature in Kelvin.

  7. Carnot Efficiency: [ \text{Efficiency} = \frac{{T_h - T_c}}{{T_h}} ] where: ( T_h ) is the absolute temperature of the hot reservoir, and ( T_c ) is the absolute temperature of the cold reservoir.

These are some of the important formulas in the chapter of Thermodynamics.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
