Find the mass of a raw egg. Cook the egg. Find the mass of the cooked egg.
Find the mass of a raw egg. Cook the egg. Find the mass of the cooked egg.
Find the mass of a piece of ice. Let the ice melt. Find the mass of the liquid water.
Find the mass of a piece of ice. Let the ice melt. Find the mass of the liquid water.
Find the mass of a cup of water. Boil the water. Find the mass of the water that remains.
Find the mass of a cup of water. Boil the water. Find the mass of the water that remains.
The procedures that could be used to demonstrate that matter is conserved during a physical change are as follows:
1. Find the mass of an apple. Cut the apple and remove the core. Find the mass of the remaining apple.
2. Find the mass of a raw egg. Cook the egg. Find the mass of the cooked egg.
3. Find the mass of a piece of ice. Let the ice melt. Find the mass of the liquid water.
4. Find the mass of a cup of water. Boil the water. Find the mass of the water that remains.
In each of these procedures, the initial mass is measured before the physical change takes place. After the physical change, the resulting mass is measured again. By comparing the initial and final masses, we can see that the mass remains the same or is very close to the initial mass. This demonstrates the conservation of matter during a physical change.
The procedure used to demonstrate that matter is conserved during a physical change involves comparing the mass of the substances before and after the change to see if there is any difference. If the mass remains the same, it indicates that matter is conserved.
For the first example, to demonstrate that matter is conserved when cutting and removing the core of an apple, you would:
1. Find the mass of the whole apple by using a scale or balance.
2. Cut the apple and remove the core.
3. Find the mass of the remaining apple by weighing it again using the same scale or balance.
If the mass of the remaining apple is the same as the initial mass, it shows that matter is conserved during the physical change of cutting and removing the core.
Similarly, for the second example with cooking an egg, you would:
1. Find the mass of the raw egg.
2. Cook the egg (boiling it).
3. Find the mass of the cooked egg by weighing it.
If the mass of the cooked egg is the same as the initial mass of the raw egg, it demonstrates that matter is conserved during the cooking process.
In the third example with melting ice, you would:
1. Find the mass of the piece of ice.
2. Allow the ice to melt and turn into liquid water.
3. Find the mass of the liquid water by weighing it.
If the mass of the liquid water is the same as the initial mass of the ice, it shows that matter is conserved during the phase change from solid to liquid.
Lastly, in the fourth example of boiling water, you would:
1. Find the mass of a cup of water.
2. Boil the water until it evaporates completely.
3. Find the mass of the remaining water by weighing it.
If the mass of the remaining water is the same as the initial mass of the cup of water, it demonstrates that matter is conserved during the process of boiling.
In all these procedures, consistency in mass indicates that matter is conserved during the physical changes being observed.
