Does the rock cycle involve both chemical and physical changes?
yes because the cycle envolves heat.
Heat which is added to a vapor after the change of state occurs is called?
Adding heat to a vapor after the change of state from liquid to vapor has occurred is called super-heating. For example, adding heat to steam at 100 C and 101.325 kPa is called super-heating.
What phase changes involve the release of heat?
The phase changes that involve a release of heat are those in which the particles move closer together. Thus, freezing is one phase change that involves a release of heat. The other such change is condensation.
What is the reaction which involves heat?
There are 2 very different reactions that involve heat. There are endothermic reactions as well as exothermic reactions that involve heat.
What is required to change the state of water?
what is the temperature at which a substance changes from a solid to a liquid called
Temperature changes are those which do not involve the addition or subtraction of heat?
Adiabatic
What is the name for temperature changes that involve no heat transfer?
Adiabatic ~ from a Greek word meaning "unable to cross" is used to refer to changes in temperature where no heat is transferred.
What occurs when matter changes from a solid to a liquid?
You are adding heat/energy. It is melting.
What is the process by which a substance changes from a liquid to a gas by adding heat?
Melting or constapation.
When matter changes from a solid to a liquid what occurred?
You are adding heat/energy. It is melting.
How water changes from ice into a gas?
By adding heat and/or reducing ambient pressure.
How can you change matter form one state to another?
By adding heat and removing heat.
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.
When does matter change state?
when water gains or loses heat, it changes its state. When liquid water gains heat, it changes its state from liquid to gas. It becomes water vapor. When solid gains heat, it melts an changes its state from solid to liquid. When gas loses heat, it condenses into liquid. Gas, to liquid. When liquid loses heat, it becomes solid
Does the rock cycle involve both chemical and physical changes?
yes because the cycle envolves heat.
Why is latent heat called hidden heat?
The latent heat of fusion refers to the heat of fusion in reactions that involve a solid that forms a liquid, or vice versa. The latent heat of vaporization is the latent heat involving a liquid that forms a gas or vice versa.Latent means hidden or unseen. In this context, the 'latent' heat is the heat that is not detectable as a temperature change in the substance. Rather than adding kinetic energy (which is detectable as a temperature change) some heat is required to break the bonds of the solid structure.
What is in salt that can melt ice?
Adding salts the freezing point of water is decreased; dissolution of salts involve releasing oh heat.
