A certain mass of ice at 00C melts into water at 00C and there by gains 1 kg mass. If initial mass of ice is m0 then –
A
m0 = 2.69 × 1011 kg
B
m0 = 1 kg
C
m0 = 2.69 × 1010 kg
D
m0 = 9 × 1016 kg
Answer
m0 = 2.69 × 1011 kg
Explanation
Solution
mc2 = m0L
1 × (3 × 108 12 = m0x (80 × 4200)
m0 = 2.67 × 1011 kg
