A 100-W lightbulb is placed in a cylinder equipped with a moveable piston. The lightbulb is turned on for 0.020 h, and the assembly expands from an initial volume of 0.90 L to a final volume of 5.88 L against an external pressure of 1.0 atm. You may want to reference (Pages 370 - 373) Section 9.3 while completing this problem. Part A Use the wattage of the lightbulb and the time it is on to calculate the heat transferred, q, in joules.

00 IN L OUniversity Science Book: presented by Macmillan Learning Stry 4th Edition McQuarrie Rock Gallogly Consider an ideal gas enclosed in a 1.00 L container at an internal pressure of 18.0 atm. Calculate the work, w, if the gas expands against a constant external pressure of 1.00 atm to a final volume of 18.0 L. Now calculate the work done if this process is carried out in two steps. 1. First, let the gas expand against a constant external pressure of 1.80 atm to a volume of 10.0 L. 2. From the end point of step 1, let the gas expand to 18.0 L against a constant external pressure of 1.00 atm. = M Question Source: McQuarrie, Rock, And Gallogly 4e - General Chemsitry Publisher.

A student is attempting to determine the heat capacity of a Styrofoam cup calorimeter by pouring hot water into a Styrofoam cup containing cold water. The student determined the mass of the cold water to be 21.2455 g and its initial temperature to be 20.36 °C. The mass of the hot water was 24.2646 g and its initial temperature as 34.54 °C. The final temperature of the water after mixing was determined to be 24.57°C. The specific heat capacity of the water is 4.184 J/(g•°C). What is the heat capacity of the Styrofoam cup calorimeter? Assume the temperature of the calorimeter is the same temperature as the cold water. 4.184 J/°C 132.5 J/°C
