What else can I help you with?
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
What happens during state of change?
Kinetic Energy is gained in the foward changes and lost in the reverse changes of state
Explain what happens when we suply heat and energy to water till it change its state What is this eat energy called?
When water has heat and energy it changes energy. The energy that it changes to is called thermal.
What happens when a substance change states?
When a substance changes state, Energy within the substance is gained or lost, but the composition is unchanged.
What happens to materials when they get hot?
When materials are heated, the kinetic energy of the atoms and molecules increases. This can lead to expansion, changes in state (solid to liquid to gas), chemical reactions, or thermal decomposition depending on the material and temperature.
What Happens to the temperature when a chemical changes state?
It remains constant, since all the energy goes into changing the intermolecular bonds.
What happens when energy is absorbed by a system?
When energy is absorbed by a system, it is taken in and used to increase the system's internal energy, which can lead to changes in temperature, state, or other properties of the system.
What happens to water as it changes state?
The density changes.
What change of state happens when something vaporizes?
what change of state happens when something melts
Identify to changes of state that require energy to be used and two changes of state that require the release of energy?
Changes of state that require energy: melting (solid to liquid) and vaporization (liquid to gas). Changes of state that release energy: freezing (liquid to solid) and condensation (gas to liquid).
How substances changes from one state to the other state?
through changes of energy
What happens when you add and subtract energy?
When you add energy to a system, its temperature increases and the particles within it move faster. This can result in an increase in kinetic energy and changes to the system's physical state. Conversely, when you subtract energy from a system, its temperature decreases and the particles move more slowly, potentially causing changes in phase or state.
