When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.
Assuming you mean changes of state i.e. solid to liquid, then if energy is supplied to matter then the particles or atoms move faster as they gain kinetic energy. This causes the bonds between the atoms to break, allowing the particles to flow over each other, as in a liquid. Like matter, energy is never created or destroyed in chemical reactions. Or: Every chemical change in matter includes a change in energy.
no physical change does not change matter
No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
Matter changing state is usually a result of the material changing temperature and/or a change in the surrounded pressure on the material. The change of state is usually associated with a change in its density.
Its where heat is taken in in a reaction eg making a cake is an endothermic reaction as heat is taken in to start it ;)
Energy can change state of matter. Heat can be used to melt ice.
Matter is nothing just a form of energy. So,either adding or removing energy,we can change the state of a matter. example:- ICE is in solid state, if we apply heat energy, it melts and changes to liquid form. Again if we apply heat energy,that liquid will change to vapour form.

What kind of energy is involved when the matter changes state?
the factors that effect the state of matter are:-temperaturepressurethe matter change their state because of the above. if the temperature increases the kinetic energy or the energy to move of the molecules and it tends to move away from each other that results in change of state. if the temperature decreases the kinetic energy decreases which pulls the molecules together and again results in the change of state.as the pressure increases the intermolecular space decreases and thereby changes the state like in the LPG (Liquefied Petroleum Gas) where petrol is pressurized to become liquid.thus we can conclude that the change of state of matter takes place to satisfy the surroundings of the matter.
Changes in the states of matter - or phase changes - do entail changes in volume.
yes. Matter can change state when thermal energy is absorbed or released.
no physical change does not change matter
no physical change does not change matter
The thing that changes during a change of state is the intermolecular forces are disrupted. The temperature will not change because all of the energy is going into disrupting or organizing the intermolecular forces.
A chaqnge of the state of matter is allways a physical change.
Matter changes state via the addition or subtraction of thermal energy. For instance, Ice melts into water, water boils into steam.
