NEET Physics (general) MCQ Question
Which of the following statements about the thermal properties of matter and heat transfer are correct?
The temperature of hot water in the calorimeter will always be higher than that of the water between the double walls.
A graph of ln(T2 - T1) versus time can be used to observe the cooling behavior of water in the calorimeter.
The behavior of gases at different temperatures is independent of the type of gas used in thermometers.
The rate of cooling of the water in the calorimeter depends on the temperature difference between the water and its surroundings.
Correct Answer
Detailed Explanation
Statement B is correct as it references the observation of temperature change over time using logarithmic representation, which aligns with the experimental setup involving thermometers and calorimeters. Statement A is incorrect because T2 can be lower than T1 as cooling occurs. Statement C is misleading since the behavior of gases can vary with type. Statement D does not fully capture the proportionality aspect stated in Newton's law of cooling.
