Answer 1

$\Large\mathbb{\red{HEAT\:AND\: THERMODYNAMICS}}$

1. ${\sf v_{rms}=\sqrt{\dfrac{3KT}{m}}}$

2. Change in internal energy in isochoric process :

${\sf \triangle U = n\dfrac{f}{2}R\triangle T}$

3. Isobaric Process ⎯ ∆W = nR${\sf (T_1-T_2)}$

4. Internal Energy ⎯ ∆U = n${\sf C_v\triangle T}$

5. Heat given ⎯ ∆Q = ∆U + ∆W

6. Specific Heat ⎯ ${\sf C_v=\dfrac{f}{2}R}$

7. Molar heat capacity of ideal gas in term of R

(1) Monoatomic gas ⎯ ${\sf \dfrac{C_p}{C_v}=1.67}$

(2) Diatonic gas ⎯ ${\sf \dfrac{C_p}{C_v}=1.4}$

(3) Triatomic gas ⎯ ${\sf \dfrac{C_p}{C_v}=1.33}$

8. ${\sf C_p-C_v=R}$ for ideal gas only

9. Adiabatic Process ⎯

∆W = ${\sf \dfrac{nR(T_i-T_f)}{\gamma - 1}}$

in cyclic process ⎯ ∆Q = ∆W

Answer 2

Answer:

Heat and Thermodynamics is an important topic from JEE Main / JEE Advanced Exam Point of view. Every year there are 1-3 questions asked from this topic. Some questions can be asked directly. This topic relates to our daily life, hence it is very easy to understand. This short notes on Heat and Thermodynamics will help you in revising the topic before the JEE Main & IIT JEE Advanced Exam.
