a study was made of the effect of the temperature on the volume of 1.00 g of helium, with the pressure held at 1 atm. The data for this experiment were: Temp(in Celsius) : -50 -10 0 25 50 100 Volume (in liters): 4.58 5.5 5.6 6.12 6.53 7.66 a. which property is the independent variable? b. prepare a graph using the data c. is there a direct relationship between the volume and the temperature of He at constant pressure 1 atm? d. at what volume would the He sample have a temperature of 5C? e. at what temperature would the He sample have a temperature of 4.20L? f. calculate the slope of the line g. calculate the y intercept of the line and write the equation for the line

Sulfur (2.56 g) was burned in a constant volume calorimeter with
excess O2(g). The temperature increased from 21.25 °C to 26.72 °C.
The bomb has a heat capacity of 923 J/K, and the calorimeter
contained 815 g of water. Calculate ΔU per mole of SO2 formed for
the reaction
S8(s) + 8 O2(g) → 8 SO2(g)

Experiment 1: Study the Relationship Between Volume and
Temperature for a Sample of Air
Took a Erlenmeyer flask & placed it on the workbench; closed
flask.
Added 1.50 atm of air to the flask.
Attached a gas syringe & thermometer to the Erlenmeyer
flask; remember the Erlenmeyer flask volume is 150 mL.
The volume of air in the syringe = 75.0 mL
The total air volume = 225.0 mL
The temperature = 21.5 C

A solution was made by adding water to 0.250 g of H2Z until the
volume totaled 25.00 mL. Subsequent titration required 40.50 mL of
0.100 M sodium hydroxide. Calculate the molar mass of H2Z (in
g/mol).
given: H2Z(aq) + 2 NaOH(aq) → Na 2Z(aq) + 2 H2O(ℓ)

A 0.905 mol sample of Ar gas is confined in a 22.6 liter container at 31.6 °C.
If the volume of the gas sample is increased to 45.2 L holding the temperature constant, the average force per molecule-wall collision will-
1) increase.
2) not enough information to answer the question.
3) remain the same.
4) decrease.
