Ideal Gas/Ideal Gas Laws

Question 1

a theoretical gas whose intermolecular forces are negligible

Answer 1

ideal gas

Question 2

change the way a gas responds to energy

Answer 2

attractive molecular forces

Question 3

when the density of a gas is low, the behavior of this gas can be ______ by the ideal gas law

Answer 3

predicted

Question 4

when the density of gas is high, the ideal gas law is ______ in predicting the gas behavior

Answer 4

inadequate

Question 5

What is the gas called when the ideal gas law is inadequate in predicting the gas behavior?

Answer 5

real gas

Question 6

States that if the temperature remained constant within a closed system, the volume of the gas varies inversely with the pressure during the change of state

Answer 6

Boyle’s Law

Question 7

States that if the pressure remained constant within a closed system, the volume of the gas varies directly with the temperature during the change of state

Answer 7

Charles’ Law

Question 8

States that if the volume of a particular quantity of gas is held constant, then, with any change of state, the pressure will vary directly as the absolute temperature

Answer 8

Gay-Lussac’s Law

Question 9

can be used to calculate thermodynamic properties without using thermodynamic tables

Answer 9

ideal gas equation or equation of state

Question 10

An ideal gas will always equal to __, and the greater it deviates from the
number __, the more it will behave like a real gas rather than ideal.

Answer 10

1

Question 11

a constant for a particular gas

Answer 11

universal gas constant (R)

Question 12

considered a perfect gas

Answer 12

air

Question 13

a thermal property that measure the heat required to increase the temperature of one unit of thermodynamic substance by one degree

Answer 13

specific heat

Question 14

relates a temperature change in a process to the change in internal energy

Answer 14

constant volume specific heat

Question 15

The change in internal energy of an ideal gas is a function of only the temperature change whether the volume remains constant or not.

Answer 15

wala lang, basahin mo lang for understanding

Question 16

relates a temperature change in a process to the change in enthalpy

Answer 16

constant pressure specific heat

Question 17

specific heat ratio for air

Answer 17

1.4

Question 18

this ratio is used for evaluating thermodynamic processes for compressors, turbines, and reciprocating engines

Answer 18

specific heat ratio

Question 19

not a constant value property; it usually increases with temperature because specific heat changes with temperature

Answer 19

specific heat ratio
