Problem 2PE

Relating Heat and Work to Changes of Internal Energy

Gases A(g) and B(g) are confined in a cylinder-and-piston arrangement like that in Figure and react to form a solid product C(s): A(g) + B(g)—>C(s). As the reaction occurs, the system loses 1150 J of heat to the surroundings. The piston moves downward as the gases react to form a solid. As the volume of the gas decreases under the constant pressure of the atmosphere, the surroundings do 480 J of work on the system. What is the change in the internal energy of the system?

Calculate the change in the internal energy for a process in which a system absorbs 140 J of heat from the surroundings and does 85 J of work on the surroundings.

Step-by-Step Solution:
Step 1 of 3

Molar Mass  If you want to know the total amount of atoms in an object you count them by weighing said object  1 dozen= 12 things o A chemist’s dozen is a mole 6.02214 X 10 23  1 gross objects=144 things  To convert you would find the mass then convert it into moles then...
