TS EAMCET · Physics · Kinetic Theory of Gases
Statement (I) : Gas thermometers are less sensitive than liquid thermometers. Statement (II) : The ratio of universal gas constant and avagadro's number is called Boltzman's constant. Statement (III) : The density of a given mass of a gas at constant pressure is inversely proportional to its absolute temperature. The correct option among the following is
- A Statements I, II, III are true.
- B Statements I, II are true, but statement III is false.
- C Statements II, III are true, but statement I is false.
- D Statements I, II, III are false.
Answer & Solution
Correct Answer
(C) Statements II, III are true, but statement I is false.
Step-by-step Solution
Detailed explanation
Thermal expansion in gases is more than thermal expansion in liquids. Therefore, gas thermometers are more sensitive than liquid thermometers. The ratio of universal gas constant and avagadro's number is called Boltzman's constant. k=RNA At constant pressure, V∝T…
