Properties of Matter & Heat MCQ questions with answers
The first 3 of 30 questions. Unlock the series for the rest, each with a solution.
Q1. When heat is supplied to a system at constant pressure, the heat exchanged is equal to the change in which of the following quantities?
जब किसी निकाय को स्थिर दाब पर ऊष्मा दी जाती है, तो विनिमयित ऊष्मा निम्नलिखित में से किस राशि में परिवर्तन के बराबर होती है?
- A. Gibbs free energy / गिब्स मुक्त ऊर्जा
- B. Internal energy / आंतरिक ऊर्जा
- C. Enthalpy / एन्थैल्पी
- D. Entropy / एन्ट्रॉपी
Solution
At constant pressure Q = ΔU + PΔV = Δ(U + PV) = ΔH, so the heat equals the change in enthalpy.
स्थिर दाब पर Q = ΔU + PΔV = Δ(U + PV) = ΔH, अतः ऊष्मा एन्थैल्पी में परिवर्तन के बराबर होती है।
Q2. The dimensional formula of Young's modulus is:
यंग प्रत्यास्थता गुणांक का विमीय सूत्र है:
- A. [M L⁻¹ T⁻²]
- B. [M L⁻² T⁻²]
- C. [M L T⁻²]
- D. [M L² T⁻²]
Solution
Young's modulus has the dimensions of stress (force/area) since strain is dimensionless, giving [M L⁻¹ T⁻²], the same as pressure.
चूँकि विकृति विमाहीन होती है, यंग गुणांक की विमाएँ प्रतिबल (बल/क्षेत्रफल) की विमाओं के समान होती हैं, जो [M L⁻¹ T⁻²] है, वही जो दाब की है।
Q3. Three of the following terms belong to the study of elasticity of solids, while one does not. Which one is the odd term out?
निम्नलिखित में से तीन पद ठोसों की प्रत्यास्थता के अध्ययन से संबंधित हैं, जबकि एक नहीं है। कौन-सा पद अलग (बेमेल) है?
- A. Capillarity / केशिकत्व (Capillarity)
- B. Elastic after-effect / प्रत्यास्थ पश्च-प्रभाव (Elastic after-effect)
- C. Elastic fatigue / प्रत्यास्थ थकान (Elastic fatigue)
- D. Elastic limit / प्रत्यास्थता सीमा (Elastic limit)
Solution
Elastic fatigue, elastic after-effect and elastic limit are all concepts in the elasticity of solids. Capillarity is a surface-tension phenomenon of liquids and is the odd one out.
प्रत्यास्थ थकान (elastic fatigue), प्रत्यास्थ पश्च-प्रभाव (elastic after-effect) और प्रत्यास्थता सीमा सभी ठोसों की प्रत्यास्थता की अवधारणाएँ हैं। केशिकत्व (capillarity) द्रवों का एक पृष्ठ-तनाव परिघटना है और यही बेमेल है।
