Question

1. Pressure is inversely proportional to volume. This is direct result of... a. Pascal's Law b. Charles' Law c. Boyle's Law d. Dalton's Law 2. Air consists of approximately 79% N2 and 21% 02, why do nitrogen molecules move faster than oxygen molecules? a. Nitrogen molecules are heavier than oxygen molecules b. Oxygen molecules are heavier than nitrogen molecules. c. Nitrogen molecules are larger than oxygen molecules d. Oxygen molecules are larger than nitrogen molecules. 3. For a gas molecule, the kinetic energy is equal to: a. kT C. KT d.-mu 2 4. If a body surface is losing heat via radiation and convection, the total heat loss is: a. the larger of the heat transfers due to radiation and convection b. the smaller of the heat transfers due to radiation and convection c. the difference between the heat transfers due to radiation and convection d. the sum of the heat transfers due to radiation and convection

Explanation / Answer

1.

P V = constant is known as Boyle's law

Correct option is C.

2.

Correct option is B.

Since Molecular weight of O2 = 32 amu

MW of N2 = 28 amu

And we know that lighter the gas faster it moves.

3.

Kinetic energy is given by:

KE = 3kT/2

Correct option is A.

4.

Correct option is D.
