Which procedure could be used to demonstrate that matter is conserved during a physica change? (1 point)
a Find the mass of an apple. Cut the apple and remove the core. Find the mass of the remaining
b Find the mass of a raw egg. Cook the egg. Find the mass of the cooked egg.
c Find the mass of a cup of water. Boil the water. Find the mass of the water that remains.
d Find the mass of a piece of ice. Let the ice melt. Find the mass of the liquid water.
c Find the mass of a cup of water. Boil the water. Find the mass of the water that remains.
The procedure that could be used to demonstrate that matter is conserved during a physical change is option a: Find the mass of an apple. Cut the apple and remove the core. Find the mass of the remaining.
To demonstrate that matter is conserved during a physical change, you would need to find a procedure where the mass of the substances before and after the change can be measured. This allows you to determine if there is any change in mass, which would indicate whether matter has been conserved or not.
Let's evaluate the options provided to identify the procedure that fulfills this requirement:
a) Find the mass of an apple. Cut the apple and remove the core. Find the mass of the remaining parts.
This procedure could demonstrate conservation of matter since cutting and removing the core does not result in the loss of any mass. The sum of the masses of the apple parts before and after the change should be equal.
b) Find the mass of a raw egg. Cook the egg. Find the mass of the cooked egg.
This procedure does not demonstrate conservation of matter. When an egg is cooked, some water content evaporates and the proteins denature, which potentially causes a change in mass. Therefore, a change in mass could indicate that matter is not conserved.
c) Find the mass of a cup of water. Boil the water. Find the mass of the water that remains.
This procedure does demonstrate conservation of matter. When water is boiled, it undergoes a physical change from a liquid to a gas but retains its mass. The mass of the remaining water should be the same as the mass of the initial cup of water.
d) Find the mass of a piece of ice. Let the ice melt. Find the mass of the liquid water.
This procedure also demonstrates conservation of matter. When ice melts, it undergoes a change from a solid to a liquid state, but the mass remains the same. The mass of the liquid water should be equal to the mass of the initial ice.
Therefore, the options (c) and (d) both include procedures that demonstrate the conservation of matter during a physical change.
