What else can I help you with?
Is a puddle freezing into ice on acold night a physical change or chemical change?
The process of a puddle freezing into ice is a physical change. This is because the molecules in the water are rearranging to form a solid state (ice) without any change in their chemical composition.
Is water evaporating from a puddle a chemical change?
Evaporation of a pudle is a physical change,
Is a puddle evaporating a reversible or irreversible change?
Yes, evaporation is the changing of matter from a liquid to a gas. You can reverse this process through condensation which is the change from a gas to a liquid.
When does non-steady state diffusion occur?
Non-steady state diffusion occurs when there is a change in concentration over time in a system.
What is a change of state-science?
A change of state in science refers to the transformation of matter from one physical state (solid, liquid, gas) to another, without changing its chemical composition. This can occur through processes like melting, freezing, evaporation, condensation, and sublimation, where energy is either absorbed or released. These changes are driven by factors like temperature and pressure.
What is it called when a puddle of water disappears?
When a puddle of water disappears, it is called evaporation. This occurs when the water's molecules gain enough energy to break free from the liquid state and turn into water vapor.
Is a puddle of dirt a chemical change?
No, a puddle of dirt is not a chemical change; it is primarily a physical change. When dirt becomes wet, its physical state changes as it absorbs water, but the chemical composition of the dirt remains the same. Chemical changes involve the formation of new substances, which does not occur in this scenario.
What change of state is when a crystal disappears from the container but does not become liquid?
Sublimation.
Is a puddle freezing into ice on acold night a physical change or chemical change?
The process of a puddle freezing into ice is a physical change. This is because the molecules in the water are rearranging to form a solid state (ice) without any change in their chemical composition.
Is water evaporating from a puddle a chemical change?
Evaporation of a pudle is a physical change,
What state of matter can make a puddle disapearpear?
The liquid state of water in a puddle can evaporate and turn into water vapor, causing the puddle to disappear.
Is a puddle evaporating a reversible or irreversible change?
Yes, evaporation is the changing of matter from a liquid to a gas. You can reverse this process through condensation which is the change from a gas to a liquid.
What must be transfered for any change of state to occur?
Energy must be transferred for any change of state to occur. A change of state is the same as a change of phase and there are four states that include liquid, solid, plasma, and gas.
Is a puddle freezing into ice on a cold night physical change?
Yes, the process of a puddle freezing into ice on a cold night is a physical change. This is because the state of matter is changing from a liquid (water) to a solid (ice) without altering the chemical composition of the substance.
Water evaporating from a puddle is a example of a?
Water evaporating from a puddle is an example of a physical change, specifically the transformation of liquid water into water vapor. This process involves a change in state from liquid to gas without altering the chemical composition of the water molecules.
What is needed for a solid to sublime and what changes of state occur?
pressure and the change of state is chemical
Does a change of state always occur in a chemical change?
not always, like the change is in the display without change in composition then it is change of state, other then will be chemical change
