Consider an ideal gas enclosed in a 1.00 L container at an internal pressure of 24.0 atm.Calculate the work, w, if the gas expands against a constant external pressure of 1.00 atm to a final volume of 24.0 L.-23.0W =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 1.50 atm to a volume of 16.0 L.2. From the end point of step 1, let the gas expand to 24.0 L against a constant external pressure of 1.00 atm.W =JJ

Step 1: first we have to find work done by the gas against external force.- pexternal(v2-v1). Step…

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
