Thermodynamics — NEET Chemistry practice

Question 1

One mole of a gas goes through states X (300 K, 20 L), Y (300 K, 40 L) and Z (600 K, 40 L). On a V–T graph, the step Z → X is a straight line through the origin. The type of process Z → X is:

Accepted Answer

Isobaric

Answer

Cyclic

Answer

Isothermal

Answer

Isochoric

Question 2

Read the Assertion and Reason carefully and choose the correct option. Assertion: In a closed system, macroscopic properties like pressure and temperature can change with time. Reason: Closed systems can exchange energy with their surroundings, which affects their macroscopic properties.

Accepted Answer

Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.

Answer

Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.

Answer

Assertion is true, but Reason is false.

Answer

Assertion is false, but Reason is true.

Question 3

Read Statement A and Statement B carefully and choose the correct option. Statement A: In calorimetry, the heat absorbed by a calorimeter is q = C·ΔT, where C is its heat capacity. Statement B: Calorimetry cannot be used to measure enthalpy changes of reactions involving gases.

Accepted Answer

Statement A is true, but Statement B is false.

Answer

Both Statement A and Statement B are true.

Answer

Statement A is false, but Statement B is true.

Answer

Both Statement A and Statement B are false.

Question 4

Match the thermodynamic terms (Column I) with their relevance (Column II). Column I: Heat; Adiabatic process; Work; Internal energy Column II: Work done on the system; Change in internal energy; No heat transfer; Depends only on state

Accepted Answer

A→Q, B→R, C→P, D→S

Answer

A→S, B→Q, C→R, D→P

Answer

A→P, B→R, C→S, D→Q

Answer

A→R, B→P, C→Q, D→S

Question 5

Match the heat-measurement terms (Column I) with Column II. Column I: Bomb calorimeter; Calorimetry; ΔU; q_p Column II: Heat at constant pressure; Internal energy change; Measurement of heat; Constant volume

Accepted Answer

A→S, B→R, C→Q, D→P

Answer

A→R, B→Q, C→P, D→S

Answer

A→S, B→Q, C→P, D→R

Answer

A→Q, B→R, C→S, D→P
