[Short Notes] Thermal Expansion & Calorimetry One Page Notes Handwritten with Short Tricks & Formula

 Thermal Expansion & Calorimetry Important points in One Page –

►Temperature scale –   Tc /5  = (Tf -32)/5 =  (Tk – 273)/5 

Reading on any scale – Lower fixed point         =            Constant for any Function             

     Upper fix point – Lower fix point

Solid Expansion =

1. Linear Expansion   [ Δl  =  αlΔT  ]

2. Areal Expansion     [ ΔA = βAΔT]

3. Volume Expansion [ΔV = γVΔT ]

   α : β : γ  = 1: 2 : 3     

 

 

► Time period of simple pendulum →   ΔT/T = 1/2αΔθ
► Thermal stress in a fixed rod        → F/A =  VαΔT
 

 

Liquid Expansion =

       1. Apparent Expansion

       2. Real Expansion

►Relation between  Yr and Yapp =

                                          Yr = Yapp + Ysolid

                                                                    Ysalid [Vs = 3x]
 

►Effect of temp Er = Eb up

(I+ YEAT) (1+YAT)

►Anomalous expansion of water: 0°C →  4°C » contraction 4°C → 100°C expansion
 

►Specific Heat       :- Required heat to raise the temperature by 1C.

► Heat Capacity    :- Required heat to change the temperature  by unity.

►Latent heat          :- Required heat to change in state with constant in temperature. [Q = mL]

Specific Heat of Water :-

C(liq.)          =    1 cal/g°C

C(ice)           =   0.5 cal/g°C

C(vapour)    =  0.48 cal/g°C

Latent Heat of Water :-

L(ice)             =  80 cal/gm

L(vapour)     =  540 cal/gm
