Is melting ice endothermic or exothermic change?
Ice cream melting (or pretty much anything melting) is an endothermic process in that it requires the absorption of heat energy in order to occur. An example of an exothermic process is the burning of paper which gives off heat energy.
How does melting point of bromine change with external pressure?
Bromine, as many other materials gets a higher melting point when pressure is low [less energy is needed to set molecules free] and lower melting point when pressure is high [more energy needed].
Why the temperature does not rise during the process of melting and boiling though the heat energy is constantly supplied?
The energy must be applied to the phase change before it can heat the substance
What processes do particles of matter absorb energy freezing and boili condensation and melting melting and vaporization or sublimation?
Particles absorb energy when boiling (vapourising), melting and subliming. Particles release energy when freezing and condensing.
How does thermal energy of water vapor change as the vapor condenses?
The thermal energy decreases as the vapor condenses.
Why is energy required for the melting or boiling process?
Energy is required in the melting process because high is needed to melt something
Is energy required for melting?
yes. It takes energy to raise the temperature of the solid to the melting point.
What is required to cause something to melt?
Melting is a change of state of a substance caused by an increase in thermal energy, so heat is required to melt a substance.
Is melting point a periodic property?
A melting point is a periodic property. Melting point is basically the amount of energy required to break chemical bonds. The more energy required, the stronger the bonds and the higher the melting point. For example, Since Ionic bonds have a transfer of electrons, it requires a lot of energy to break the bonds and has a higher melting point.
What is the energy required to melt a solid at its melting point?
heat of fusion
How is energy related to the change of state?
Well...kinetic energy is involved with melting
Is melting of wax reversible change?
You can easily un-melt it, i.e., wait for it to cool down and get hard again. However, the energy required for melting can't be recovered (useful energy gets converted into unusable energy), so in that sense, this process (and most processes in nature) are irreversible.
What requires more energy melting or boiling?
Melting requires energy input or absorption because liquid water has more energy than solid water.
Does melting require the absorption of energy?
Yes, it does to change state
During which change is energy absorbed?
the melting of ice
What is the phase change from liquid to solid?
solidifying or freezing, releasing energy to the environment.
What is required to change a solid to a liquid?
energy is required
