Question
For an ideal gas*1 point(a) Size of molecules is negligible.(b) There is no force of attraction or repulsion amongst the molecules.(c) It strictly obeys the gas laws.(d) All of the above.
Solution
(a) Size of molecules is negligible.
- In an ideal gas, the size of molecules is considered to be negligible. This means that the volume occupied by the molecules themselves is insignificant compared to the total volume of the gas.
(b) There is no force of attraction or repulsion amongst the molecules.
- Another characteristic of an ideal gas is that there are no forces of attraction or repulsion between the molecules. This implies that the molecules do not interact with each other, except during collisions.
(c) It strictly obeys the gas laws.
- An ideal gas strictly obeys the gas laws, such as Boyle's law, Charles's law, and Avogadro's law. These laws describe the relationships between pressure, volume, temperature, and the number of molecules in the gas.
(d) All of the above.
- The correct answer is (d) All of the above. All the statements (a), (b), and (c) are true for an ideal gas.

Choose TRUE or FALSE for each of the following statements.A. A real gas can have intermolecular forces but then the Ideal Gas Law (PV=nRT) doesn't apply. B. Pressure is the force applied per unit area. C. The units on R do not need to match the units of P, V, and T. As long as a pressure, volume, and temperature are put into the equation, the answer will be correct. D. When temperature is used in any gas law, the temperature MUST be in Kelvin. E. For a mixture of ideal gases, the pressures can be added because for ideal gases, the identity of the gas doesn't matter.
