What else can I help you with?
Are boiling and melting the same?
No boiling is heating and energy is added and melting the solid turns into a liquid.
Under what conditions heat can be given to a substance without raising its temperature?
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
Will there be effect on melting or boiling point of a substance if another substance is added to it?
Yes, impurities have important effects on the melting and boiling point of materials.
Why does the temperature of a substance remain constant during it's melting point on boiling point?
Because of phase transition ie from solid to liquid during melting and from liquid to vapour during boiling. So just to change over from one phase to the other heat is totally utilized and hence no chance to have a rise in temperature. So temperature remains constant.
How is the melting point of asolid and boiling point of a liquidaffected when impurities are added to the substances?
Adding impurities lowers the melting point and raises the boiling point.
Compare the temperature of a cup of ice with and without salt added to it?
They would be relatively the same temperature, it's just the melting point which is changed.
Why doesn't the temperature of boiling water change as heat continues to be added?
The temperature of boiling water remains constant at the boiling point (100°C at sea level) because the added heat energy is used to convert the liquid water into water vapor, rather than increasing the temperature. This phase change absorbs heat without affecting the temperature.
If heat is added to a saturated vapor and raises the vapors temperature above its boiling point the heat is referred to as?
The heat added to a saturated vapor to raise its temperature above its boiling point is referred to as sensible heat. This is because the heat causes a change in temperature without a phase change.
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 temperature remains constant at melting and boiling point of substance?
The temperature remains constant at the melting and boiling points of a substance because all the energy added during these phase changes is used to break intermolecular bonds rather than increase the kinetic energy of the molecules. During melting, the energy breaks the bonds holding the solid structure together, while during boiling, it overcomes the forces keeping the liquid molecules together. As a result, temperature does not rise until the entire substance has completely transitioned to the next phase.
How can you add thermal energy to a substance without increasing its temparature?
One way to add thermal energy to a substance without increasing its temperature is through a phase change, such as melting or boiling. During these changes of state, the added energy is used to break the bonds between molecules rather than increasing their kinetic energy, resulting in a temporary plateau in temperature.
Why does temperature remain constant during melting and boiling?
During melting and boiling, the energy being added to the substance is used to break the intermolecular forces holding the molecules together, rather than increasing the kinetic energy of the molecules. This means that the temperature remains constant because the energy is absorbed as the substance undergoes a phase change.
