What mass of ice taken at the melting temperature can be melted by imparting heat to ice Q = 167 J?
| February 9, 2021 | education
Q = 167 Joules – the amount of heat that is imparted to the ice;
q = 330 kJ / kg = 330,000 J / kg is the specific heat of melting of ice.
It is required to determine m (kilogram) – how much ice can be melted using the amount of heat equal to Q.
Since, according to the condition of the problem, the ice is already at the melting temperature, that is, additional heating is not required, then the mass can be determined from the following formula:
Q = q * m, from here we find that:
m = Q / q = 167/330,000 = (167/330) * 10-3 = 0.5 * 10-3 kilograms (0.5 grams).
Answer: By imparting a heat of 167 Joules to the ice, you can melt 0.5 grams of ice.
