Why do substances change phases when energy is added or removed?
When energy is added to a substance, the temperature of the substance increases, causing the particles to gain kinetic energy and move faster, resulting in a phase change. Likewise, when energy is removed from a substance, the temperature decreases, causing the particles to slow down and the substance to change phases. The energy absorbed or released during these phase changes is used to either break or form bonds between the particles.
Why do particles lose their attraction and change from one state to another?
Particles lose their attraction and change states due to changes in energy levels. When energy is added or removed, particles can overcome intermolecular forces and transition from solid to liquid to gas states. This is because the kinetic energy of the particles determines their motion and ability to break away and move freely.
Sometimes heat energy is added but the temperature stays the same when is this?
When a substance undergoes a phase change, such as melting or boiling, heat energy is added, but the temperature remains constant. This is because the added energy is being used to break the intermolecular forces holding the substance together, rather than increasing the kinetic energy of the particles.
If enough energy is added to a solid it will change state what is possible Particles in the solid will?
When enough energy is added to a solid, the particles within it will gain kinetic energy, causing them to vibrate more vigorously. As the energy increases, these vibrations may overcome the forces holding the particles in fixed positions, leading to a transition from the solid state to the liquid state (melting). In this liquid state, the particles are still close together but can move past one another, allowing for flow.
How is energy related to the change of state represented by the model?
Energy plays a crucial role in the change of state by influencing the movement and arrangement of particles. When energy is added to a substance, such as during heating, particles gain kinetic energy, which can lead to a transition from solid to liquid (melting) or liquid to gas (vaporization). Conversely, when energy is removed, such as during cooling, particles lose kinetic energy, resulting in a change from gas to liquid (condensation) or liquid to solid (freezing). This energy exchange is essential for understanding phase transitions in matter.
What happens to energy added during a phase change?
The added energy is used in the phase change to break intermolecular bonds.It is used for the phase change. ~ APEX
Why do substances change phases when energy is added or removed?
When energy is added to a substance, the temperature of the substance increases, causing the particles to gain kinetic energy and move faster, resulting in a phase change. Likewise, when energy is removed from a substance, the temperature decreases, causing the particles to slow down and the substance to change phases. The energy absorbed or released during these phase changes is used to either break or form bonds between the particles.
What change in state requires an energy to be added to the substance?
The change from solid to liquid, liquid to gas, and solid to gas all require an input of energy to overcome intermolecular forces holding the particles together. This added energy breaks these forces, allowing the particles to move more freely and change state.
What happens to particles inside of a solid liquid or gas when energy is added compared to when energy is removed?
When energy is added to a solid, liquid, or gas, the particles move faster and have more energy, causing them to vibrate, rotate, or move around more. This can lead to a phase change, such as melting or boiling. When energy is removed, the particles slow down and may eventually bond together to form a new phase, such as solidification or condensation.
Why do particles lose their attraction and change from one state to another?
Particles lose their attraction and change states due to changes in energy levels. When energy is added or removed, particles can overcome intermolecular forces and transition from solid to liquid to gas states. This is because the kinetic energy of the particles determines their motion and ability to break away and move freely.
If enough energy is added to matter in the liquid state it will change into different state. During this change of state the particles would?
move faster and break free from other particles, entering the gas state.

When a substance undergoes a phase change, such as melting or boiling, heat energy is added, but the temperature remains constant. This is because the added energy is being used to break the intermolecular forces holding the substance together, rather than increasing the kinetic energy of the particles.

What happens to the motion of water particules when heat energy is added to the water?
Molecules move faster when heat energy is added to to water. The water temperature mayincrease or some or the molecules may get enough energy to change phase from solid to liquidor from liquid to vapor.
What happens to the particles of matter when thermal energy is added to it?
When thermal energy is added to matter, the particles within the matter begin to vibrate more rapidly and with greater energy. This increased thermal energy causes the particles to move more freely, which can lead to changes in state (such as melting or boiling) or expansion of the matter.
What is the relationship between energy and temperature change?
When heat is transferred in a space the average energy of the particles - the temperature of the substance - is affected, by increasing or decreasing. The change in temperature depends on the number of particles affected.
What is a measure of the energy of motion of the particles in a substance?
Particle motion increases as energy (like heat) is added. The motion slows as energy leaves. Temperature is a measure of this change in particle motion.
