Q) If a wire of Resistance 20 is covered with ice (at 0⁰C) and a vltage of 210V is applied across the wire, then the rate of melting of ice----

1) 0.85 g/s      2) 1.92 g/s     3) 6.6 g/s    4) none

HERE POWER , DEVELOPED

BY RESISTANCE =   S0

THIS IS USED AS MELTING OF ICE  SO

LATENT HEAT OF FUSION = 334

SO  *RATE

SO RATE OF MELTING OF ICE = 6.6g/s

wll i think i m right

PLZ RATE

BEST OF LUCK
