Interpretation Introduction

(a)

Interpretation:

Differences among items in each of the following groups are to be stated - Particulate-level explanation of characteristics of gases, kinetic molecular theory

Concept introduction:

The size and nature of gas molecules is stated by particulate level explanation of gases. Commonly, the presence of intermolecular forces and the rapid movement of gas molecules can be explained by kinetic theory of gases. During the fast movement the molecules collide with the walls of the container. Thus, the gas molecules are termed to be in some pressure values.

Answer to Problem 55E

Commonly, the states of matter such as gas, liquid, and solid can be explained by particulate level concepts by considering them as microscopic particles. The development of particulate theory as kinetic molecular concepts extends the concept of gas molecules with their size, volume, attractive forces, average kinetic energy of gas molecules, and the interaction among the gas molecules.

Answer to Problem 55E

Boyle’s law states that at constant temperature volume of a gas is inversely proportional to its pressure. According to Charles’s law, at constant pressure the volume of a gas is directly proportional to its pressure. Amontons’s refers that at constant volume the pressure of a gas varies directly with the increase in temperature. Combined gas includes the variations of pressure, volume, temperature of an ideal gas as PV = nRT.

Answer to Problem 55E

The measurement of heat of a system is measured as ‘temperature’ and the force that acts on the system in unit area is measured as ‘pressure’. When the temperature of a system (T °C) is 0 °C and the pressure is 1 atm then the conditions are referred as standard temperature and pressure of the system. At STP the kelvin unit of temperature is having the value of 273 K, (TK) and 32 °F (T °F).
