Why is a candle melting a chemical change?
Melting is accompanied by burning and thermal degradation - two chemical reactions.
During a temperature change what is happening to the substance?
A change of phase: melting, evaporation, liquefaction or chemical changes as thermal dehydration, thermal decomposition, oxydation, etc.
What is the changing of matter from a solid state to a liquid state called?
Melting is the change from solid to liquid.
Does the melting temperature of a solid change with the amount of material?
i do not care what you stupid idiots want to know
Is sugar melting in warm water physical or chemical change?
Physical. Because it includes thermal changing. But not melted because of acid or other chemical substances.

What change when the amount of a substance change?
total thermal energy
Is scorching butter a physical or chemical change?
Melting is a physical change; but above a temperature the thermal decomposition of butter begin - this is a chemical change.
Scorching butter chemical or physical change?
Melting of butter is a physical change, a change of phase; but the brown color, at high temperature, is an indication of thermal decomposition - this ia a chemical change (change of composition).
What energy is involved in ice changing to liguid?
Thermal energy, melting of ice is a physical change of phase.
Exposure of butter to atmosphere a chemical or physical change?
Melting in a warm atmosphere is a physical change; but the oxydation in air or the thermal degradation of butter are chemical changes.
How can the temperature of substance remain the same even if the substance is absorbing thermal energy.?
For example, when ice is melting, the absorbed thermal energy is used to change the phase of the substance - a type of potential energy.
How does thermal energy of solid water change as its melting?
The thermal energy of the water increases as it melts, changing from a solid (ice) to liquid water. For a solid to melt, it is necessary for it to absorb energy from its surroundings.
What are the steps to prove that a burning of a candle is physical as well as a chemical change?
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
What is the amount of change in the thermal energy of a certain mass of a substance per degree of change in temperature?
That is called the specific heat.
What is the changing of matter from a solid state to a liquid state called?
Melting is the change from solid to liquid.
