The Law that states the summation of each of the partial pressure of the component gases in a gas mixture equals to the total pressure is:
Dalton's Law
What is the name of the gas Law that expresses how the volume of a sample of gas depends on the pressure that confines the gas
Boyle's Law (P1v1 = P2V2)
Provide the name of the gas Law that expresses how the volume of a gas varies directly with the absolute temperature at constant pressure.
Charles' Law (V1/T1 = V2/T2)
At constant volume, the pressure and absolute temperature are directly related. Which gas Law expresses this relationship?
Gay-Lussac Law (P1/T1 = P2/T2)
What is the formula for the ideal gas equation?
PV = nRT
What is the name of the specific temperature and pressure beyond which liquid and gas phases become indistinguishable?
The Critical Point (consists of Critical T & P)
What is the name of the specific temperature and pressure at which a substance exists as a solid, liquid and gas simultaneously in equilibrium?
Triple Point
What is the formula to calculate potential energy?
m x g x h
The energy of a chemical system that includes the energy due to the volume the system occupies, at constant pressure is called ____________
Enthalpy
What is the symbol for the energy change of a chemical system as a result of any process that carries the system from some initial state to some final state?
∆𝑈 or ∆𝑈system
In a bomb calorimeter, what is the name of the compartment where the sample is placed in?
Vessel or bomb
Many reactions are not suitable for direct calorimetric study. The internal energy or enthalpy changes can often be obtained by an indirect method. What is the name of this method?
Hess Law of heat summation.
What is the analytical expression (or formula) for molar heat capacity at constant pressure, which can be used for temperatures ranging from 298 K to 2000 K?
(CP = ________________ )
CP = a + bT + c/T2
Two important statements of the second law of thermodynamics have been given by two renown scientists, name them.
1. Lord Kelvin (William Thomson) and,
2. Rudolf Clausius
In the first law of thermodynamics, we study the thermodynamic universe, which consists of the system, its thermal surroundings and mechanical surroundings.
In the second law, what are the components of its thermodynamic universe?
Same (System, thermal and mechanical surroundings), no change.
