hands - on lab observe states of matter observe the shapes of a solid and liquid in different containers. investigate how the volume of a solid, liquid, and gas may change and explain how the properties of each state of matter differ. procedure and analysis step 1 draw 10 ml of air into the syringe. record the initial volume in the table below. step 2 tighten the cap onto the end of the syringe, if one is available. alternatively, you can press your finger against the end of the syringe to act as a cap. push in the plunger. record the final volume and any other observations. safety note: always point the tip safely away from others when pushing in the plunger. step 3 observe the shape of the marbles in the cup. remove the plunger and place the marbles in the syringe. then replace the plunger so the bottom of the plunger touches the top of the marbles. record the volume and observations. step 4 tighten the cap. push in the plunger. record the volume and observations. step 5 observe the shape of the water in the cup. remove the marbles from the syringe and replace the plunger. then draw 10 ml of water into the syringe. record the volume and observations. step 6 tighten the cap. push in the plunger. record the volume and observations. observations gas (air) solid (marbles) liquid (water) initial shape not visible shape in syringe not visible initial volume final volume additional observations hands - on lab worksheet 1 of 2 matter exists in different states

Explanation:

Step1: Initial volume of gas (air)

According to the procedure, the initial volume of air drawn into the syringe is 10 mL. So for gas (air), initial volume = 10 mL.

Step2: Initial volume of solid (marbles)

The marbles are placed in the syringe and the volume is recorded. But we need to measure it during the experiment. Let's assume we measure and find it to be \(V_{s - initial}\) (actual value depends on measurement).

Step3: Initial volume of liquid (water)

We draw 10 mL of water into the syringe. So initial volume of water = 10 mL.

Step4: Final volume of gas (air)

When we push in the plunger on the air - filled syringe (with cap tightened), air is compressible. Let's assume after pushing we measure the final volume as \(V_{a - final}\) (actual value depends on how much we push).

Step5: Final volume of solid (marbles)

Solids are not compressible. So if no marbles are removed, the final volume of marbles is the same as the initial volume \(V_{s - initial}\).

Step6: Final volume of liquid (water)

Liquids are not compressible. So if no water is removed, the final volume of water is the same as the initial volume, 10 mL.

Step7: Initial shape of solid (marbles)

The marbles take the shape of the cup they are in initially. So it's the shape of the bottom - part of the cup.

Step8: Shape in syringe of solid (marbles)

The marbles take the shape of the cylindrical part of the syringe they are in.

Step9: Initial shape of liquid (water)

The water takes the shape of the cup it is in initially, which is the shape of the bottom - part of the cup.

Step10: Shape in syringe of liquid (water)

The water takes the shape of the cylindrical part of the syringe it is in.

Step11: Additional observations for gas (air)

Air is compressible, we can feel resistance while pushing the plunger.

Step12: Additional observations for solid (marbles)

Marbles are hard, do not change volume under normal pressure applied by the plunger.

Step13: Additional observations for liquid (water)

Water does not compress under the normal pressure applied by the plunger, and it flows when the syringe is tilted.

Answer:

	Gas (air)	Solid (marbles)	Liquid (water)
Shape in syringe	not visible	Cylindrical shape of syringe	Cylindrical shape of syringe
Initial volume	10 mL	Measured value \(V_{s - initial}\)	10 mL
Final volume	Measured value \(V_{a - final}\)	\(V_{s - initial}\)	10 mL
Additional observations	Compressible, feel resistance while pushing plunger	Hard, non - compressible	Non - compressible, flows when tilted
