A Beaker of Negligible Heat Capacity Contains 456 G $- 25.0 ^ { \circ } \mathrm { C }$

question 59

Short Answer

A beaker of negligible heat capacity contains 456 g of ice at $- 25.0 ^ { \circ } \mathrm { C }$ A lab technician
begins to supply heat to the container at the rate of 1000 J/min . How long after starting will
it take before the temperature starts to rise above $0 ^ { \circ } \mathrm { C } ?$ The specific heat of ice is $2090 \mathrm {~J} / \mathrm { kg } .$ $\mathrm { K }$ and the latent heat of fusion of water is $33.5 \times 10 ^ { 4 } \mathrm {~J} / \mathrm { kg }$
