Find the amount of heat required to melt 500 gram ice taken at 0 degrees Celsius
| June 17, 2021 | education
The amount of heat required to melt ice (0 ºC is the melting point of ice and no additional heating is required) can be calculated using the formula:
Q = λ * m, where λ is the specific heat of melting of ice (λ = 3.4 * 10 ^ 5 J / (kg * K)), m is the mass of ice taken (m = 500 g = 0.5 kg).
Let’s calculate the required amount of heat:
Q = λ * m = 3.4 * 10 ^ 5 * 0.5 = 1.7 * 10 ^ 5 J = 170 kJ.
Answer: To melt 500 grams of ice, 170 kJ of heat is required.
