Heat tranfer is the method used to do this. Removing the heat from a system changes its state by changing the molecular structure of the system being used. Say it is water(H2o), if heat is removed from water it changes the energy level of the molecules by removing energy and causing the molecules to hold close to eachother. This creates a solidifying effect creating ice. If the opposite is done and heat is added to water, energy is added. The molecules then are energized and get to the point of not being able to be close to eachother seperating and going off on their own. Thus creating steam.
What else can I help you with?
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
Why does the temperature remains constant during the change of state?
During the time of change of state,the heat or temperature is used to increase the potential energy and there by change of state.This time there will be no change in temperature.
Why does the temperature remain constant at the transition temperature even though heating is continued?
At the transition temperature, the heat goes into causing the change in state. Once the change in state is complete, the temperature will change.
Sensible heat involves a change in a substance's?
Sensible heat involves a change in a substance's temperature without a change in its phase. It is the heat exchange that causes a change in the temperature of a substance but does not result in a change of state (solid, liquid, gas).
Does the temperature of a substance changes before the change of state is completed?
No. During a phase change the temperature is constant until the phase change is complete.
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
What state will most likely result if heat is added to a liquid?
It will change into a gas.Adding heat to or removing heat from a system may result in a temperature change and possibly a change of state. A liquid substance needs heat added to it in order to enter a gaseous state. If enough heat is added to a liquid substance it will change into a gas.
What happens to the temperatures of a substance while it is changing state?
It can lose or gain energy or it forms the attractions between particles.
Why does the temperature remains constant during the change of state?
During the time of change of state,the heat or temperature is used to increase the potential energy and there by change of state.This time there will be no change in temperature.
Why does the temperature remain constant at the transition temperature even though heating is continued?
At the transition temperature, the heat goes into causing the change in state. Once the change in state is complete, the temperature will change.
How can one determine the entropy change in a system?
One can determine the entropy change in a system by calculating the difference between the entropy of the final state and the entropy of the initial state, taking into account any heat transfer and temperature changes.
Change of what causes a change of state?
Temperature or pressure
Does the change of a temperature cause matter to change state?
It can.
Does a change of temperature can cause a change of state?
True
How does temperature change during change of physical change?
Temperature remains constant during the change in phase (physical state).
Sensible heat involves a change in a substance's?
Sensible heat involves a change in a substance's temperature without a change in its phase. It is the heat exchange that causes a change in the temperature of a substance but does not result in a change of state (solid, liquid, gas).
What causes a change in state of matter?
Temperature.
