What is a property of matter that is always the same no matter what size the sample?
One example of a property that remains constant regardless of sample size is density. Density is the mass of a substance per unit volume, and it stays the same no matter how much of the substance is present.
Is heating copper carbonate a chemical change?
Yes, heating copper carbonate is a chemical change because it undergoes thermal decomposition to form new substances, copper oxide and carbon dioxide. This is a chemical reaction that results in the formation of different compounds with distinct properties.
What happens when you change the composition of a mixture and a compound?
When you change the composition of a mixture, you are altering the relative amounts of the substances mixed together, while their chemical properties remain the same. In contrast, changing the composition of a compound involves altering the elements that make up the compound, leading to the formation of a new substance with different chemical properties.
Is a glass of juice frozen melted and refrozen a chemical or physical change?
physical :D I hope that helps
Do leaves change color the same time every year?
Not always. The weather and the temperature have a lot to do with it. If it stays warm they change later, if it gets cold sooner they change sooner.
When matter undergoes a physical or chemical change the amount of mass changes or stays the same?
In physical changes, the amount of mass stays the same because no new substances are formed. In chemical changes, the amount of mass stays the same due to the law of conservation of mass, which states that mass cannot be created or destroyed, only rearranged into different substances.
What is change in which the composition of matter stays the same?
physical change
Can matter be changed or moved?
Matter can not change. Its weight always stays the same NO MATTER WHAT, and it can be moved
Does your mass change on the planets?
Your mass stays the same no matter where you are. Your weight will change.
What characteristics best describe what happen during a physical change?
The compsitions stays the same :0
Is dissolving of salt a chemical change?
No, it is a physical change.
What happens to substances temperature during a change of state?
Temperature remains constant
When sugar is dissolving is that a chemical or physical change?
The change is physical because the change is reversible. Evaporate the water and you are left with the sugar, no new substances are produced; the sugar stays sugar and the water, water.
What are the characteristics of a controlled variable?
A controlled variable means that it stays the same while other substances change. This helps prove the exact changes in an experiment.
What stays indoors no matter how many times you put it out?
What stays indoors no matter how many times you put it out?
How does expansion and contraction of matter differ from a change in state of matter?
the matter always stays the same, expansion and contraction just means the matter is becoming more/less spread out from one another. A change in the state of matter is turning from solid-liquid-gas. The amount of matter always stays the same!
What breaks down substances but stays the same?
A catalyst.
