Determine the specific latent heat of fusion of ice given the amount of time it takes the ice to melt (150 seconds). Energy is supplied to the ice at 530 W. The sample is .25 kg.
Homework Equations
Q= ml
The Attempt at a Solution
(Time * 530W) = .25kg * L
150 seconds * 530W = .25kg * L
(150 * 530)/.25 = 318,000
This seems huge, can anyone help me determine what the units are?
The Latent Heat of Fusion is the amount of energy required to change a substance from a solid state to a liquid state at its melting point. It is a specific type of latent heat, which refers to the energy absorbed or released during a phase change without a change in temperature.
The Latent Heat of Fusion for ice is commonly measured in joules (J) or calories (cal) per gram (g). It is determined by dividing the amount of energy absorbed or released during the phase change by the mass of the substance.
The Latent Heat of Fusion for ice is primarily affected by the type of substance and the atmospheric pressure. Other factors, such as impurities in the ice or the rate of heating, may also have a small impact on the value.
The Latent Heat of Fusion for ice plays a crucial role in the Earth's climate by regulating the temperature of the planet. When ice melts, it absorbs a significant amount of heat energy from the environment, helping to cool the Earth. Similarly, when ice freezes, it releases heat energy into the environment, helping to warm the Earth.
Yes, the Latent Heat of Fusion for ice has several practical applications. It is used in refrigeration and air conditioning systems, as well as in the production of frozen foods and ice cream. It is also utilized in the creation of artificial snow and in the storage of food and medical supplies at below-freezing temperatures.
