What is always involved when physical or chemical changes occur in matter?
When physical changes occur in matter, the substance's state or appearance changes without altering its chemical composition. In contrast, chemical changes involve a modification in the substance's chemical composition, resulting in the formation of new substances.
How does sublimation compare with other changes of state?
Sublimation occur directly from a solid to a gas, jumping over the liquid phase.
Which occurs more often on earth physical changes or chemical changes?
Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.
What conditions does physical change occur in materials?
Physical changes in materials occur when the material undergoes a change in its physical properties without any change in its chemical composition. Examples of conditions that can cause physical changes include changes in temperature, pressure, or exposure to light or electricity. Physical changes can include changes in state (such as melting or freezing), changes in shape or size, or changes in properties (such as conductivity or solubility).
What can occur when matter changes state?
when matter changes state either evolution or absorption of enrgy occurs for example when a solid changes to liquid or a liquid changes to gas energy is absorbed and in case of conversion of gas to liquid or liquid to solid enrgy is liberated....
What change of state occur when water changes to gas?
gas
What is needed for a solid to sublime and what changes of state occur?
pressure and the change of state is chemical

What are phyisical changes?
Physical changes refer to alterations that affect the appearance or state of a substance without changing its chemical composition. Examples include changes in shape, size, color, or state (solid, liquid, gas). These changes are usually reversible and do not involve the formation of new substances.
How does sublimation compare with other changes of state?
Sublimation occur directly from a solid to a gas, jumping over the liquid phase.
What changes of state occur when wax runs down the side of a candle?
The wax on a candle transitions from solid to liquid as it melts from the heat of the flame. As the liquid wax drips down the side, it cools and solidifies back into a solid state. So, the changes of state that occur are melting (solid to liquid) and solidification (liquid to solid).
What are reflections that occur at changes in impedance?
Return loss refers to the reflections that occur at changes in impedance.

What are temperature changes that occur even though heat is not added or subtracted?
Temperature changes may occur due to changes in pressure, volume, or physical state of a substance, known as adiabatic processes. This is governed by the ideal gas law, which relates pressure, volume, and temperature of a gas. Additionally, temperature changes can result from chemical reactions or phase changes within a system.
Can chemical change and physical change happen simultaneously?
No, chemical changes and physical changes are distinct processes that occur separately in a system. Chemical changes involve the formation of new substances with different chemical properties, while physical changes involve alterations in the state or appearance of a substance without changing its chemical composition. These processes do not typically occur simultaneously.
