guys.. i no the way im supposed 2 solve these bt having trouble getting answer...so plz. solve nd tell mah..these r frm hcv. vol2..caloremetry 6] a cube of iron [density 8000kg per m3 specific heat capacity 470j/kg/k ] is heated 2 a high temp nd is placed on a large ice block of ice at 273k .. the cube melts the ice belo it, displaces the water nd sinks..in the final eq. position, itz upper surface is just inside . calculate initial temp of cube..neglet radiations...density of ice 900kg/m3 latent heat of fusion..336000j/kg ans..353k 12]a brick of mass 4kg is dropped into a 1 m deep river frm a ht 2m..assume 80%of PE is converted into thermal energy...find thermal energy in calorie... ans...23cal.... plz..reply...ill certailnly rate u.....u can answer at least 1...

6] a cube of iron [density 8000kg per m3  specific heat capacity 470j/kg/k ] is heated 2 a high temp  nd is placed on a large ice block of ice at  273k .. the cube melts the ice belo it, displaces the water nd sinks..in the final eq. position, itz upper surface is just inside . calculate initial temp of cube..neglet radiations...density of ice 900kg/m3  latent heat of fusion..336000j/kg
 
ans..353k
 
 
12]a brick of mass 4kg is dropped into a 1 m deep river frm a ht 2m..assume 80%of PE is converted into thermal energy...find thermal energy in calorie...
