Question

800 cal are supplied to a large block of ice at 0°C . How much ice will melt?​

Answer 1

Answer:

full ice blogs will melt.........

Answer 2

Answer: A/C to thermodynamics ,

Heat flow from higer temperature body to lower temperature body

Heat loss by water = Heat gain by ice

Given, mass of water = 80gm

specific heat of water = 1 Cal/gm/°C

∴ Heat loss by water = MS∆T

= 80 × 1 × (30 -0)

= 80 × 1 × 30

= 2400cal

Heat gain by ice = MLf

Lf is latent heat of fusion = 80Cal/gm

M is the mass of melted ice

Now, 2400 = 80M

M = 30gm

Hence , 30gm of ice is melted .
