Substances can change state, usually when they are heated or cooled. For example, liquid water turns into steam when it is heated enough, and it turns into ice when it is cooled enough. The closeness, arrangement and motion of the particles in a substance change when it changes state.
What else can I help you with?
What are two physical changes that cooling a hot substance may result in?
Cooling a hot substance may result in the condensation of its gaseous state into a liquid state. It may also cause the solidification of a liquid into a solid form as the substance loses its heat energy and transitions to a lower temperature state.
Melting is not the same as evaporation because?
melting is the process of a substance changing from a solid to a liquid state due to an increase in temperature, while evaporation is the process of a substance changing from a liquid to a gas state due to heat energy. Melting involves a phase change from solid to liquid, while evaporation involves a phase change from liquid to gas.
What does not result in a new substance being formed?
A physical change, such as melting ice or cutting paper, does not result in a new substance being formed. These changes only affect the physical state of the matter, not its chemical composition.
What two things are unaffected in physical change?
The chemical composition is not changed.
Is a change that produces a new substance is a chemical change?
False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.
What are two observations you might make when a physical change occurs?
Change in state: One observation would be a change in the physical state of the substance, such as from solid to liquid or gas. Reversibility: Another observation might be that the physical change is typically reversible, meaning the substance can return to its original state by reversing the process that caused the change.
What are two ways that a substance can be described?
mixture or a compound
What are two effects caused by a chemical change?
Two effects that are caused by a chemical change are changes from one substance into another. Another effect that can be caused by a chemical change is a change in the temperature of the surrounding system and substance, or a change in color of the substance.
What two ways does the suns position in the sky change?
what two ways does the suns position change in the sky
Why did The two party largely offered a choice between?
The two party system offer a choice between Change and Established Ways
Is it true melting is considered an sublimation change because energy is gained by substance as it changes stae?
Melting is a phase change in which a substance changes from the solid state to the liquid state. Sublimation is a phase change in which a solid moves directly into the gas phase. Both melting and sublimation are two types of physical change.
What are two physical changes that cooling a hot substance may result in?
Cooling a hot substance may result in the condensation of its gaseous state into a liquid state. It may also cause the solidification of a liquid into a solid form as the substance loses its heat energy and transitions to a lower temperature state.
What are two physical properties that can vary even when the substance with these properties dose not change?
Density and color can vary while the substance remains the same. Density is mass per unit volume, which can change depending on pressure or temperature. Color can vary due to factors such as lighting conditions or impurities in the substance.
What two determine the state of a substance?
Temperature and pressure
What are two examples of change that is not caused by energy and explain?
One example is a phase change, such as ice melting into water, where energy is used to change the state of the substance without altering its temperature. Another example is a chemical reaction where the bonds between atoms are broken and rearranged without a change in energy, resulting in a new substance.
What are two physical properties that can vary even when the substance with these properties does not change?
Density and temperature can both vary for a substance without changing the identity of the substance. The density of a substance can change with temperature, pressure, or the presence of impurities, while the temperature of a substance can change due to external factors like heating or cooling.
What are two ways in which the physical state of matter can be changed?
Two ways in which physical state of matter can be changed:- changing the temperature- changing the pressure
