What represents a physical change?
For example the transformation of liquid water in vapors (vaporization).
What happens if you take 2 styrofoam cups and fill one with cold water and one with hot water and drop a glow stick in each?
The glow stick in the cold water will not glow as bright as the glow stick in the hot water because when you cool the glow stick down, the chemical process will slow down. The glow stick in the hot water will glow brighter but for a shorter period of time.
What happens when you throw hot water into cold air?
When hot water is thrown into cold air, the water quickly evaporates and turns into steam. This happens because the cold air causes the hot water to rapidly cool down, leading to a phase change from liquid to gas.
What are 2 examples of a chemical change?
When iron is exposed to oxygen in the air, it undergoes oxidation to form rust, changing its chemical composition from iron to iron oxide. When baking soda is mixed with vinegar, a chemical reaction occurs that produces carbon dioxide gas, water, and a salt, resulting in the formation of new substances with different properties than the original reactants.
How do the positions of hot and cold water affect the speed of convection?
noting it works (in the science meaning; to cause a change) a lot.
Is suger in hot water is it a chemical or physical change?
Dissolution is a physical change.
Is dissolving suger in hot water a chemical or physical?
Dissolving sugar in hot water is a chemical change.
Is hot glass cracking when placed into cold water a chemical or physical change?
It is a physical change because the chemical composition of the glass does not change.
When Sugar dissolves in hot water a physical or chemical change?
When sugar dissolves in hot water, it is a physical change. This is because the sugar molecules are simply mixing with the water molecules but are not undergoing a chemical reaction to form new substances.
Is mixing coffee with hot water a physical or chemical change?
Mixing coffee with hot water is a physical change because the individual substances (coffee and water) retain their chemical identities and only the physical state of the coffee changes, dissolving in the water. No new substances are formed.
Is adding hot water to pot noodles a physical change?
Adding hot water to pot noodle is a physical change because the chemical nature of water remain unchanged.
Is adding hot water to pot noodles chemical or physical?
Adding hot water to pot noodles is a physical change. The hot water causes the noodles to absorb the water and soften, changing their physical state without altering their chemical composition.
Is sugar dissolves in hot water a chemical change or physical change?
The dissolving of sugar in hot water is a physical change because it does not alter the chemical composition of either the sugar or the water. The sugar molecules are merely dispersed throughout the water molecules.
When the banana, berries, water, and hot dog are blended, does a physical or chemical change occur?
both physical and chemical change occur
Is a cooked hot dog physical or chemical change?
CHEMICAL:)
Is dissolving milo into hot water a physical change?
The instant coffee and the water have not changed chemically or physically. It becomes a mixture, not a solution; the water is separate from the coffee powder. Therefore it is not a physical change.
Is using hot water to expand a metal cup a physical or chemical change?
Using hot water to expand a metal cup is a physical change. The change in size and shape of the cup is due to the expansion of the metal atoms when heated, but the chemical composition of the metal cup remains the same.
