What else can I help you with?
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).
Why is kinetic energy more in liquid state?
Than in ??what?? state Kinetic energy is greater in liquid state because the liquid substance is moving. If the kinetic energy was less than in liquid state, the object of the state would become solid.
What is a change of state in which energy is added as it changes state?
Solid --> Liquid. Liquid -> Gas. Solid --> Gas.
Do water molecules in the liquid state have more energy than water molecules in the polar state?
Do water molecules in the liquid state have more energy than water molecules in the polar state
Which change in state requires that energy be added to the substance?
Melting solid into liquid requires energy to be added to the substance.
How is the state of mattr related to the amount of energy in a substance?
The state of matter is related to the amount of energy in a substance through the kinetic energy of its particles. As a substance gains energy, its particles move faster, causing a change in state (solid to liquid, liquid to gas) as the intermolecular forces are overcome. This change in energy affects the arrangement and movement of particles, determining the state of matter.
Can the state of matter change when you add or take away energy?
Yes, particularly if you add thermal energy. At its least energetic, matter is in the solid state. Add some more energy, it transitions to the liquid state. Then more and it's a gas. Finally, at its most energetic, it is in the plasma state.
What change of state and what energy changes occur when water freezes?
the state change is from liquid to solid and the energy change is cold energy to heat energy
What is the energy needed for a substance to change from a liquid state to a gaseous state?
thermol
What is the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state is called?
The process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state is called evaporation. This occurs when the kinetic energy of the molecules overcomes the intermolecular forces holding them in the liquid state.
Does liquid to gas take in energy?
of course! when there is a change of state it ALWAYS uses energy
What state are electrons at their lowest possible energy level?
liquid
