Part 1: Temperature-Volume Relationship (Charles’s Law)
Objectives:
1. Investigate the relationship between volume and temperature constant pressure of gas using the given data.
2. Calculate for each unknown on volume and temperature relationship at constant pressure of a gas
Directions. Complete the table below and answer the guide question that follows. Data of Volume-Temperature Relationship at
Constant Pressure
Guide Questions: 2 pts. Each.
1. What do you observe about the volume and temperature of the given data?
2. Given that the pressure is constant, what do you observe about the quotient of volume and temperature (K) in each trial?
3. Given a constant pressure, what do you think will happen to the volume if the temperature decreases? increases?
4. Given a constant pressure, what do you think will happen to the temperature if the volume decreases? increases?
5. Make volume vs temperature graph at constant pressure using the data given above. 5 pts.
6. State the relationship between volume and temperature at constant pressure using the graph. 2 points

Part 2: COMPUTATION: Temperature-Volume Relationship (Charles’s Law)
The volume - temperature relationship in gases was determined by and named after Jacques Charles. Charles’s Law states
that the volume of a gas is directly proportional to its temperature at constant pressure. It means that as the temperature
increases, the volume also increases and as the temperature decreases, the volume decreases as shown in the table in Activity 2. You
will also notice in the given table that the quotient of pressure and volume are always the same which leads us to Charles’s Law
equation.
Direction. Solve the following problem using Charles’s Law equation
