Lesson: Specific Latent Heat Physics • 9th Grade
In this lesson, we will learn how to use the formula E = mL to calculate the amount of energy absorbed or released by a change in the state of a material.
Sample Question Videos
1 kg of copper and 1 kg of nickel are both heated continuously at the same rate. Determine which metal will completely melt first. Use a value of 205 kJ/kg for the specific latent heat of fusion of copper and use a value of 297 kJ/kg for the specific latent heat of fusion of nickel.
Which of the following is the correct unit for the specific latent heat of fusion?
Water in a pan reaches , but the pan is still left on the heat, so eventually all of the water turns to water vapor. Calculate the energy needed to evaporate the 1.2 kg of water contained by the pan. Use a value of 2,258 kJ/kg for the specific latent heat of vaporization of water. Give your answer to the nearest kilojoule.
