Cooling down and as such not in thermal equilibrium.
Typically the solid will both increase in temperature and expand, as the heat energy delivered to the solid causes its molecules to vibrate faster and to increase their spacing.

There are three types of transferrable energy: conduction, convection, and radiation. Conduction- heat that moves from solid object to solid object by physical means. Convection- heat that moves about a gaseous object (think about boiling water) Radiation- light energy that can travel through space and needs no object to transfer through. The correct answer for this question would be radiation.
Because it absorbs heat and changes from the solid to liquid state.
Its temperature declines, and it may change phase ... from liquid to solid, or from gas to either liquid or solid.
It absorbs energy.
Any solid black object does that.
Typically the solid will both increase in temperature and expand, as the heat energy delivered to the solid causes its molecules to vibrate faster and to increase their spacing.
An endothermic change; or a change of state. Endothermic because it absorbs energy. Change of state because ti changes from a solid to a liquid.
Some gasses turn into liquids when compressed (propane, butane), some turn into liquids when chilled to very cold temperatures (oxygen, nitrogen).
this is a description of melting - when a solid absorbs energy - that is, gets hot - and becomes liquid - that is, it melts
yup

The solid absorbs energy from the surroundings, causing the molecules to move around and no longer be in a tight structure (solid) but moving around fairly easy (liquid).
heat will escape a window by conduction as is it a solid, if something is touching it, by convection, as a fluid (air included) moves past it, and by radiation since thermal energy will always flow from hot to cold.
A match. Solid rocket fuel.
the state change is from liquid to solid and the energy change is cold energy to heat energy
