Properties of Solids and Liquids MCQ questions with answers
The first 3 of 20 questions. Unlock the series for the rest, each with a solution.
Q1. Consider the following statements about thermal expansion: 1. For an isotropic solid, the coefficient of volume expansion is three times the coefficient of linear expansion. 2. Water has its maximum density at about 4 °C. 3. When a metal plate with a circular hole is heated, the diameter of the hole decreases. Which of these statements is/are correct?
तापीय प्रसार के संबंध में निम्नलिखित कथनों पर विचार कीजिए: 1. समदैशिक ठोस के लिए आयतन प्रसार गुणांक, रेखीय प्रसार गुणांक का तीन गुना होता है। 2. जल का घनत्व लगभग 4 °C पर अधिकतम होता है। 3. जब वृत्ताकार छिद्र वाली धातु की प्लेट को गर्म किया जाता है, तो छिद्र का व्यास घट जाता है। इनमें से कौन-सा/कौन-से कथन सही है/हैं?
- A. 1, 2 and 3 / 1, 2 और 3
- B. 1 and 3 only / केवल 1 और 3
- C. 1 and 2 only / केवल 1 और 2
- D. 2 and 3 only / केवल 2 और 3
Solution
For an isotropic solid γ = 3α, and water shows anomalous expansion with maximum density near 4 °C, so statements 1 and 2 are correct. Statement 3 is wrong because a hole expands on heating exactly as a disc of the same material would.
समदैशिक ठोस के लिए γ = 3α, तथा जल असंगत प्रसार दर्शाता है जिसमें लगभग 4 °C के निकट अधिकतम घनत्व होता है, अतः कथन 1 और 2 सही हैं। कथन 3 गलत है क्योंकि गर्म करने पर छिद्र ठीक उसी प्रकार फैलता है जैसे उसी पदार्थ की चकती फैलती।
Q2. Which one of the following is NOT an assumption made in deriving Bernoulli's theorem for fluid flow?
तरल प्रवाह के लिए बरनूली प्रमेय के निगमन में निम्नलिखित में से कौन-सी मान्यता नहीं ली जाती है?
- A. The fluid is incompressible / तरल असंपीड्य है
- B. The fluid is non-viscous / तरल अश्यान है
- C. The flow of the fluid is turbulent / तरल का प्रवाह विक्षुब्ध (turbulent) है
- D. The flow is steady and streamlined / प्रवाह स्थायी और धारारेखीय है
Solution
Bernoulli's theorem assumes steady, streamline flow of an incompressible, non-viscous fluid. Turbulent flow violates the steady-flow assumption, so it is not an assumption of the theorem.
बरनूली प्रमेय में असंपीड्य, अश्यान तरल के स्थायी, धारारेखीय प्रवाह की मान्यता ली जाती है। विक्षुब्ध (प्रक्षुब्ध) प्रवाह स्थायी-प्रवाह की मान्यता का उल्लंघन करता है, अतः यह प्रमेय की मान्यता नहीं है।
Q3. Match List I (elastic constant) with List II (defining ratio). List I: A. Young's modulus; B. Bulk modulus; C. Modulus of rigidity; D. Poisson's ratio. List II: 1. Lateral contraction strain divided by longitudinal elongation strain; 2. Longitudinal stress divided by longitudinal strain; 3. Shearing stress divided by shearing strain; 4. Normal stress divided by volumetric strain. Select the correct matching:
सूची I (प्रत्यास्थ नियतांक) का सूची II (परिभाषित करने वाला अनुपात) से मिलान कीजिए। सूची I: A. यंग गुणांक; B. आयतन प्रत्यास्थता गुणांक; C. दृढ़ता गुणांक; D. पॉयसन अनुपात। सूची II: 1. पार्श्व संकुचन विकृति को अनुदैर्ध्य दैर्घ्य-वृद्धि विकृति से विभाजित करने पर; 2. अनुदैर्ध्य प्रतिबल को अनुदैर्ध्य विकृति से विभाजित करने पर; 3. अपरूपण प्रतिबल को अपरूपण विकृति से विभाजित करने पर; 4. अभिलंब प्रतिबल को आयतनिक विकृति से विभाजित करने पर। सही मिलान चुनिए:
- A. A-2, B-4, C-1, D-3
- B. A-4, B-2, C-3, D-1
- C. A-2, B-3, C-4, D-1
- D. A-2, B-4, C-3, D-1
Solution
Young's modulus is longitudinal stress/longitudinal strain (2), bulk modulus is normal stress/volume strain (4), rigidity modulus is shear stress/shear strain (3), and Poisson's ratio is lateral strain/longitudinal strain (1).
यंग गुणांक अनुदैर्ध्य प्रतिबल/अनुदैर्ध्य विकृति (2) है, आयतन प्रत्यास्थता गुणांक अभिलंब प्रतिबल/आयतन विकृति (4) है, दृढ़ता गुणांक अपरूपण प्रतिबल/अपरूपण विकृति (3) है, तथा पॉयसन अनुपात पार्श्व विकृति/अनुदैर्ध्य विकृति (1) है।
