Is butter melting in a pan a physical change that absorbs energy?

Is butter melting on warm toast a chemical or physical property?
It is a physical property. A chemical property would involve the butter reacting to the toast, but the butter is actually reacting to the heat from the toast. The butter would melt against any surface hot enough, where as butter would not melt on cold toast. Hence, the reaction to heat makes it a physical property. (A relatively easy way to remember is that physical properties deal with the transfer of physical energy or force such as heat, inertia, etc. Chemical properties occur when two material substances trade molecules or electrons.)
When substances are given energy they may change state This is a physical change If they do not receive enough energy to change state they will still experience a physical change What is this call?
heating

Is energy change a chemical or physical change?
Conduction of energy is a physical change.
Which of the changes of state shown in the figure require an increase in energy answers?
Evaporation uses energy to change from a liquid to a gas. Melting uses energy to change from a solid to a liquid. Condensation releases energy to change from a gas to a liquid. Freezing releases energy to change from a liquid to a solid.

What is a exothermic change?
It is when something releases its energy to its surroundings do to a system.
Sodium metal in chlorine gas releases energy is it a physical property?
No this is a chemical change- sodium reacts with chlorine gas to form sodium chloride and a lot of heat.
