Can an object change its physical state even though it does not absorb energy?

A puddle of water may freeze. Anything liquid might solidify. Because going in that direction it releases energy, which it must get back if it is to return to its former state.

How heat is absorbed?
Physical objects absorb heat when the molecules of which they consist absorb energy and increase their velocity. Molecules are always moving, or vibrating in a lattice structure. They can absorb energy through physical collisions with molecules of another object or medium (air, water), or through direct absorption of radiant energy. In either case, the molecules then increase their velocity and the object of which they are a part are said to become hotter, having absorbed heat.
Is temperature change a physical or chemical change?
Temperature is the perception we have of the vibrational energy of the molecules in any substance. The faster they vibrate, the hotter the object. So the answer is physical.
How the thermal energy of an object changes when the objects temperature changes?
when abody is heated definitely its thermal energy increases so far that it can even cause a change in its physical appearance
What happens to energy during a phase change?
Energy either transfers to the object or leaves the object.
Is grinding matter a physical change?
grinding any substance would by a physical change, because they are still that object

Is the size of an object a physical property or physical change?
An object's size is a physical property of the object.
What happens when scientists add heat energy to an object or take heat energy away from an object?
as scientists add heat too an object , the objec begin to pre-heat and began to dissolve .
Why does a large object absorb thermal energy faster than a smaller object?
A greater surface area allows for greater energy transfer.
Why is change of color a physical change?
Because a physical change just alters the appearance of an object, where as a chemical change alters the texture or state of an object.
What changes and what doesn't change in a physical change?
The changes and constant features in a physical change depend on the object tested. The makeup of the object does not change but the visual may.
Is temperature change a physical or chemical change?
Temperature is the perception we have of the vibrational energy of the molecules in any substance. The faster they vibrate, the hotter the object. So the answer is physical.
What does an object have if it is able to produce a change in itself or its surrounding?
The object has energy.
When does light energy change to thermal energy?
When an object absorbs light energy the object can get warmer.
Is an orange a physical or chemical change?
An orange is a physical object and is not any kind of "change"!
