a sample of tin is heated until it finishes melting. the sample absorbs a total of 1050 j of heat. if the sample requires 460 j of heat to reach its melting point, how much heat is needed to completely melt the sample of tin?

Respuesta :

The quantity of heat energy required to convert solid stuff into liquid is known as the heat of fusion. Q = mHf is the formula. The temperature is not a factor because matter does not change temperature.

What transpires to heat energy when a phase shift occurs?

The molecules are able to move farther apart from one another thanks to the heat energy that is generated during the phase shift, which helps to overcome some of the forces holding them together. The additional heat energy is converted during the phase change into potential energy, also known as the energy of position because the molecules are now farther apart.

Does increasing the temperature when a phase transition is being added heat?

The temperature of solid water rises when heat is applied, reaching its melting point at 0 °C. By adding heat at this time, the phase change transforms the substance from a solid to a liquid. The temperature can only rise once this phase change is finished.
