Depends what you mean - your question is not clear - but consider :-
At STP Oxygen and Hydrogen are two elements in the gaseous physical state BUT their compound Water is in the liquid state.
At STP Oxygen is gaseous and Iron is solid BUT their compound is Iron Oxide is solid.
So the answer is no.

Does physical state of matter always change during a chemical change?
No. Two elements of the same state can combine and still be in the same state in the end product.
How can you use ionic compound in a sentence?
An ionic compound always exists in solid state.
How many elements does a compound made of?
A 'compound' is composed of several 'elements'. Don't confuse them with the 'atom'/'molecule' distinction - e.g. H20 is a compound because it has H and O, but Hydrogen in its natural state comes as H2 (2 H atoms), but still only ONE element (H).
Is evaporating alcohol a chemical change?
No. It is a physical change as the actual compound does not change, only its state does.
What is a physical change and what makes a chemical change?
physical change may be change in colour,odour,state(solid liquid gas) of any compound but chemical behavior of that compound remains as such; while when compound's chemical composition is changed than it is called chemically changed...
Does physical state of matter always change during a chemical change?
No. Two elements of the same state can combine and still be in the same state in the end product.
How does a compound affect scientific experiments?
Compounds are chemically-combined elements. Very few elements exist in an uncombined state, so various physical or chemical reactions are needed to move elements from one state to another. Some physical operations include: Smelting (a heating operation) is used to remove metals from ore. Fractional distillation (vaporization and cooling) can separate mixtures of various compounds and elements.
How do you determine the physical state of the compound?
You determine It.. obviously

How can you use ionic compound in a sentence?
An ionic compound always exists in solid state.
Ionic compounds are normally in which physical state at room temperature?
Solidlike salt (NaCl) which is an Ionic compound.
Is melting iron into liquid a chemical change?
No, all changes of state are physical, never chemical. It always can be reversed by temperature change only and no other compound are involved.
What is the oxidation state of a lone elements?
It is always 0.
What is a compound of xenon oxide?
There is no such thing as that, oxidation state (number) refers to the "state" of the elements in the compund.
What is the most common elements present on jupiters physical state?
IUNNO
Is the state of matter considered a physical property?
The state of matter of a element or compound is linked to its melting and boiling points which are both physical properties. Also if the element/compound is a solid you could say physical properties on the type of structure it would form
What is the diffrenece between an element and a compound?
Element is the simplest form of substance while compound is a substance of combined elements. Compound can be broken down into simpler substances which maybe are another form of compounds or just in the simplest state which are elements
