KEY:
- to make into
= this is what you do
solid - liquid = melting
solid - gas/gas - solid = sublimation
liquid - solid = freezing
liquid - gas = evaporation
gas - liquid = condensation
They all involve heating up or cooling down the state.
Hope this helps(:

Do all changes involve interaction?
Yes
What two changes of state does this process involve?
In order to know what two changes of state are involved in a process one needs to know what the process is.
Do all changes involve physical interaction?
no they don't
Does changes in a state of matter involve a physical change?
A chaqnge of the state of matter is allways a physical change.
What does the change in state involve?
A change of state is a change in the object from a solid to a liquid. Other changes of state are a solid to a gas or from a liquid to a solid.
Which of the phase changes does not involve changing a liquid into a gas?
All the rest of them.
How are chemical and physical change alike?
They are alike because #1 they are a change insubstance, #2 the form is different. I hope i have been a huge help to people who need this for homework!
What changes of state would involve water absorbing energy?
From water at solid state or ice change to liquid the process is called melting. From water as solid to gas the process is called sublimation. From water as liquid to gas the process is called evaporation. All these 3 processes involve change of state and absorb heat.
What are reversibile reactions?
Reversible reactions usually involve a reaction that changes the physical state of the substance, not the chemical properties
Do physical changes involve change in energy?
Yes, physical changes involve a small change in energy.
Do all objects easily accept changes in their state of motion?
All objects resist changes in their state of motion
Enthalpy changes accompanying a change of state are than those accompanying the heating of a substance at each state?
Any change of state involve a change of the system enthalpy.
