mujhe question no. 1 ki samjh nai aai hai.
Q= m (Lf + cicc delta Ticc + c water delta T water )
is may mujhe value add kr k do plz chowder
Q=1.80(Lf =3.34*105J/kg+cice = 2100J/kg.K deltaTice cwater =4190J/kg.K delta T water)
plz help me in question no. 1 according to assignment.
mujhe samajh nai aai hai. value put kr k batayon?
So volume =l*l*l=l^3
T1=20C and T2=90C
Given that p=1.01*10^5 Pa
(a) increase in volume of cube=?
As V2 –V1= B(T2-T1)
V2-V1=5.1*10^-3 *.0008 *343
Increase in volume =133994.4*10^-7 m3
(b) work done=?
W=1.01*10^5 *133994.4 * 10^-7
(c) heat added=?
At constant pressure,Cp=Qp/deltaT
Qp=Cp *delta T
(d) as Q=delta U +W
masoor sb please help me in question no. 1
