Answer:
d. 0.043 g/s
Explanation:
Formula for rate of conduction of heat through a bar per unit time is as
follows
Q = k A ( t₁ - t₂ ) / L
A is cross sectional area and L is length of rod ,( t₁ - t₂ ) is temperature
difference . Q is heat conducted per unit time
Putting the values in the equation
Q = (427 x 1 x 10⁻⁴ x 100 )/ 30 x 10⁻²
= 14.23 J/s
mass of ice melted per second
= Q / Latent heat of ice
= 14.23 / 334000
= 0.043 g/s
