A `10 H` inductor carries a current of `20A`. How much ice at `0^@C` could melted by the energy stored in the magnetic field of the inductor? Latent heat of ice is `22.6xx10^I3J//kg`

What is meant by saying that the latent heat of fusion of ice is 3.34 xx 10^(5)J//kg ?

In an inductor of inductance L=100mH , a current of I=10A is flowing. The energy stored in the inductor is

A 0.2 H inductor is connected across an AC power supply . The current in the circuit increases from 0 to 3.4 A. Calculate the energy stored in magnetic field of inductor during that period.

A piece of ice falls from a height h so that it melts completely. Only one-quarter of the heat produced is absobed by the ice and all energy of ice gets converted into heat during its fall. The value of h is [Latent heat of ice is 3.4 xx 10^(5) J//kg and g = 10 N//kg ]

A piece of ice falls from a hight h so that it melts completely. Only one quarter of the heat produced is absorbed by the ice and all energy of ice gets converted into heat during its fall. The value of h is : (Latent heat of ice is 3.4xx10^(5) j//kg and g=10N//kg )

Four resistances carrying a current shown in Fig. 7.41 are immersed in a box containing ice at 0^(@)C . How much ice must be put in the box every 10 min to keep the average quantity of ice in the box constant? Latent heat of ice is 80 calg^(-1) .

How should 1 kg of water at 50^(@)C be divided in two parts such that if one part is turned into ice at 0^(@)C . It would release sufficient amount of heat to vapourize the other part. Given that latent heat of fusion of ice is 3.36xx10^(5) J//Kg . Latent heat of vapurization of water is 22.5xx10^(5) J//kg and specific heat of water is 4200 J//kg K .

How many grams of ice at 0^@C can be melted by the addition of 500 J of heat ? (The molar heat of fusion for ice is 6.02 Kamal^(-1))

Prove the energy stored in a current inductor, per unit volume is (B^(2))/(2mu_(0)) , where B is the magnetic field inside the inductor.

A 42 kg block of ice moving on rough horizontal surface stops due to friction, after sometime. If the initial velocity of the decelerating block is 4ms^-1 , the mass of ice (in kg) that has melted due to the heat generated by the friction is (Latent heat of ice is 3.36xx10^5Jkg^ -1
