What else can I help you with?
What two things deep beneath the earth's surface can change any rock into a metamorphic rock?
heat and pressure in the earths crust with little if any chemical change.
How does igneuos rock get changed into metamorphic rock?
Heat and Pressure.
How was metamorphic made?
an igneous or sedimentary rock that is changed by heat or pressure
Why does metamorphic rock often form deep within earths crust?
Metamorphic rocks are rocks which have been changed by heat an pressure. The deeper you go within the earth, the more heat and pressure there is, which is why metamorphic rocks form there.
What can change any rock into a metamorphic rock?
intense heat and pressure.
The heat exchange in chemical reactions is due to a change in?
The chemical composition of reactants is changed.
When does the change in enthalpy equal heat in a chemical reaction?
The change in enthalpy equals the heat in a chemical reaction when the reaction occurs at constant pressure.
How do minerals change?
THEY can change. they due to heat intense pressure and due to chemical changes. they can change their color.
What alters the form or phase of a sudstance but not its chemical identity?
Heat or pressure can change its form but not chemical identity.
What can an igneous rock be changed into?
An igneous rock can change into a metamorphic rock with heat or pressure.
Heat exchange in chemical reactions is due to a change in what?
Enthalpy-The heat added to or loss by a system at constant pressure
In a firework show the fireworks explode giving off heat and light is this a chemical change why?
It is a chemical change because the chemical composition is changed during this reaction.
Is frying eggs a chemical change or a physical change?
Chemical. The chemical composition of the egg is changed when the egg is fryed, and cannot be reversed.
Is welding a physical change or chemical change?
Welding is a physical change because it involves the joining of two pieces of metal through the application of heat and pressure, without altering the chemical composition of the base materials.
Which rock means 'changed'?
Metamorphic, changed by pressure and heat
What happens to energy during a chemical change?
when a chemical change occurs, chemical bonds are broken up
Heat of reaction for a chemical reaction symbol?
The symbol used to represent the heat of reaction in a chemical equation is ΔH. It indicates the enthalpy change of the reaction, which is the heat exchanged during a chemical reaction at constant pressure.
