Water has three states
Solid (ice)
liquid (water)
gas (steam)
When water is heated it expands and when it is cooled it contracts until about 4 degrees Celsius when it begins to expand again.
So the answer to your question is it depends on what temperature the water is. If it is a liquid and over 4 degrees then it will expand. If it is not frozen but somewhere between 0 and 4 degrees it will contract until about 4 degrees and then expand. Under 0 degrees it is ice not water, over 100 degrees it is steam not water.

What is the difference between heat of reaction and molar heat of reaction?
Heat of a reacion is the totall amount of heat a reaction produces. Molar heat of a reaction is the heat produced/mol if you have the molar hear of the reaction you can calculate the heat of the reaction based on the moles of reactants you have
What is the relationship between the heat of reaction and the heat of formation in a chemical reaction?
The heat of reaction is the difference between the heat of formation of products and reactants in a chemical reaction. It represents the amount of heat released or absorbed during the reaction. The heat of formation is the heat change when one mole of a compound is formed from its elements in their standard states. The relationship between the two is that the heat of reaction is related to the heat of formation of the substances involved in the reaction.
What is the difference between the heat (q) of a reaction and the reaction enthalpy (Hrxn)?
The heat (q) of a reaction is the amount of energy transferred as heat during a chemical reaction, while the reaction enthalpy (Hrxn) is the overall change in heat energy of a reaction at constant pressure. The main difference is that heat (q) is the actual energy transferred, while reaction enthalpy (Hrxn) is a measure of the total heat change in a reaction.
What is the difference between enthalpy and heat of reaction in a chemical reaction?
Enthalpy is the total heat content of a system, including both heat absorbed and released during a reaction. Heat of reaction specifically refers to the heat released or absorbed when a specific chemical reaction occurs.
Is the heat of reaction the same as enthalpy?
No, the heat of reaction is not the same as enthalpy. Enthalpy is a measure of the total heat energy in a system, while the heat of reaction specifically refers to the heat energy released or absorbed during a chemical reaction.

What is heat of the reaction is releasesd?
If heat from a reaction is released, it is an exothermic reaction.
What is the relationship between the heat of reaction and the chemical reaction?
The heat of reaction is the amount of heat released or absorbed during a chemical reaction. It is a measure of the energy change that occurs as reactants are converted into products. The relationship between the heat of reaction and the chemical reaction is that the heat of reaction indicates whether a reaction is exothermic (releases heat) or endothermic (absorbs heat).
What is the relationship between the heat of reaction and a chemical reaction?
The heat of reaction is the amount of heat energy released or absorbed during a chemical reaction. It is a measure of the reaction's energy change. The relationship between the heat of reaction and a chemical reaction is that the heat of reaction indicates whether a reaction is exothermic (releases heat) or endothermic (absorbs heat). This information helps us understand the energy changes that occur during the reaction.

What is a heat reaction?
This the heat released during a chemical reaction.
Energy is lost from a reaction in a form of what?
Energy is lost from a reaction in the form of heat. This heat is often referred to as exothermic heat, as it is released from the system during the reaction.
How are endothermic reaction different from exothermic reaction?
Exothermic reaction: with release of heat Endothermic reaction: with absorption of heat
How does temperature affects reaction rate?
if the reaction is exothermic (creates heat) then adding heat will cause the reaction to run in the reverse direction if the reaction is endothermic (requires heat) then heat will speed it up
What happens in an endothermic reaction?
An endothermic reaction need heat to occur.
A chemical reaction that gives off heat is most likely to be what?
An endothermic reaction is one that consumes heat.
What is the difference between the heat (q) of a reaction and the reaction enthalpy (Hrxn)?
The heat (q) of a reaction is the amount of energy transferred as heat during a chemical reaction, while the reaction enthalpy (Hrxn) is the overall change in heat energy of a reaction at constant pressure. The main difference is that heat (q) is the actual energy transferred, while reaction enthalpy (Hrxn) is a measure of the total heat change in a reaction.
