Answer:
Explanation:
SO in order to calculate the specific latent heat of fusion, you need to remember the formula:
Where 
representes the specific latent heart of fusion.
represents the heat energy added, usually represented in kJ
represents the mass of the object, in kg.
Now that we have our formula we just have to put our values into the formula:
SO our answer would be
The changes in the energy law of conservation of energy is Potential energy is converted to kinetic energy. Kinetic energy is converted into potential energy.
<h3>What is the law of conservation of energy?</h3>
Law of conservation of energy says that energy can neither be created nor destroyed, it just transformed from one form to another.
The energies are kinetic, potential, mechanical, gravitational, electrical, etc.
Thus, the changes in the energy law of conservation of energy is Potential energy is converted to kinetic energy. Kinetic energy is converted into potential energy.

Answer:
A is the correct option
Explanation:
batteries have chemical energy and will convert to electricity and when reached to bulb, it emits light as electromagnetic rays
Answer: A chemical process must occur and then changes between the state of the reactants and the state of the products can be determined
Explanation: Enthalpy represents the sum of the energy of the system with the product of the pressure and volume of that system. As a thermodynamic property, it expresses the ability to release heat from the system. In fact, enthalpy tells us how much heat and work has changed during the chemical reaction under constant pressure. When measuring, measurements of the difference in enthalpy between the two states of the system is performed, before and after the chemical reaction, since total enthalpy can not be measured. This measurement of the enthalpy change can tell us, for example, whether the heat was released from the system during the reaction, or the system absorbed the heat.
Mixture. Distilled Water may be a pure substance, however, there are many minerals and such that are in tap water, making it a mixture.
