Why does wax melt in boiling water?
Wax has a lower melting point than boiling water, so when placed in boiling water, the heat from the water causes the wax to melt. The molecules in the wax absorb the heat energy from the water, which ultimately leads to the wax melting.
What is boiling and melting and condensation best described as?
The three of boiling, melting, and condensation describe matter change of state.Boiling is sate change from liquid to gasmelting is state change from solid to liquidcondensation is state change from gas to liquid
Why does the temp stay the same when boiling and melting?
The temperature stays the same during boiling and melting because the heat energy is being used to break intermolecular forces rather than raise the temperature. During boiling, this energy is used to convert the liquid into vapor, while during melting, it is used to convert the solid into a liquid.
Why does temperature does not rise during the process of melting and boiling through heat energy is constantly supplied?
During melting and boiling, the temperature remains constant because the heat energy supplied is used to break intermolecular bonds rather than increase kinetic energy. In melting, energy disrupts the structured arrangement of solid particles, while in boiling, it allows liquid particles to escape into the gas phase. This phase change requires energy, but does not result in a temperature increase until the phase transition is complete.
Why do melting and boiling absorb energy?
Melting and boiling absorb energy because they involve breaking intermolecular forces. During melting, energy is required to overcome the attractive forces holding solid particles together, allowing them to move freely as a liquid. Similarly, during boiling, energy is needed to separate liquid molecules from one another to enter the gaseous state. This energy absorption is known as latent heat, which does not raise the temperature but facilitates the phase transition.
What requires more energy melting or boiling?
Melting requires energy input or absorption because liquid water has more energy than solid water.
How is melting and boiling alike?
They are both phase changes, this means that until the melting or boiling are complete the temperature of the system remains at the melting or boiling point, despite the continued input of heat energy.

Water changes phases when heat is added or subtracted?
Boiling and melting are endothermic. Freezing is exothermic.

Why does temperature does not rise during the process of boiling and melting though heat energy is constantly supplied?
you must have observed during the experiment of melting that the temperature of the system does not change after the melting point is reached till all the ice melts this happens even though we continue to heat the breaker that is we continue to supply heat
Can heat be added to a substance without causing temperature of the substance to rise?
Yes, if the heat goes into a phase change.For example . . .Heat added to ice at 0° C changes the ice to water at the same temperature.Heat added to water at 100° C changes the water to steam at the same temperature.
Why do metallically bonded compounds have high melting and boiling points?
Metallically bonded compounds have high melting and boiling points due to the strength of their bonds. Metallic bonds are very strong and therefore take a lot of energy to break, which could be heat. This is why lots of heat energy is needed to break down each individual metallic bond
Is there a release or absorption at heat in phase change?
It depends on the phase change. When going from solid to liquid (melting), liquid to gas (boiling), or solid to gas (sublimation) heat is absorbed. When going from gas to liquid (condensation), liquid to solid (freezing), and gas to solid (deposition) heat is released.
