2. EXOTHERMIC ENDOTHERMIC

3. Continuous evaporation taking place in an uncovered container. In the covered container, a state of dynamic equilibrium (liquid-to-gas-to liquid) exists.

6. Lab 1. COMPRESSIBILITY OF LIQUIDS AND GASES 1. Pull the plunger of the syringe to admit air into it. Record the initial volume of air. 2. Push the plunger. Record the final volume. 3. Fill the syringe with water. Record the initial volume. 4. Push the plunger. Record the final volume. 5. Solve and compare the change in volume of air and water. 6. Which is more compressible: liquid or gas?

7. Lab 2. EFFECT OF CONTAINER ON THE VOLUME AND SHAPE OF A LIQUID. 1. Draw the shape and record the volume of the liquid in container A. 2. Transfer the liquid into container B. Draw the shape and record the volume of the liquid in container B. 3. Transfer the liquid into container C. Draw the shape and record the volume of the liquid in container C. 4. Color your liquid shape. 5. Write your conclusion about the effect of container on the shape and volume of a liquid.

8. Lab 3. VOLUME OF LIQUID AND GAS 1. Mark the initial level of the liquid butane in the lighter. 2. Fill a 50 ml graduated cylinder with water. Seal the opening with parafilm. 3. Invert the graduated cylinder in a pan of water. Remove the cover 4. Place the lighter under the opening of the graduated cylinder. Depress the lighter valve under water so that the gas will enter the graduated cylinder up to the 50 ml mark. 5. Measure the change in the level of the liquid butane in the lighter. 6. Solve for the change in the volume of the liquid butane using the formula L x W x H. (Use cm as the unit) 7. What is the ratio of the volume of gas to volume of liquid?
