A)
Identify the following system and process is,
- • steady state, at equilibrium, or neither.
- • Isothermal, isobaric, isochoric, adiabatic closed, or open system is applicable or not
System: An ice cube
Process: The ice cube is inside a freezer, where is has already been for some time before the process begins. The process lasts 24 hours, during which the freezer door is never opened.
B)
Identify the following system and process is,
- • steady state, at equilibrium, or neither.
- • Isothermal, isobaric, isochoric, adiabatic closed, or open system is applicable or not
System: An ice cube
Process: The ice cube is inside a freezer. The freezer door is opened, allowing room temperature air in. The door is open for one minute, and the process ends 10 minutes after the door is closed.
C)
Identify the following system and process is,
- • steady state, at equilibrium, or neither.
- • Isothermal, isobaric, isochoric, adiabatic closed, or open system is applicable or not
System: The air inside a hot air balloon.
Process: The balloon rises from the ground to a height of 1000 feet.
D)
Identify the following system and process is,
- • steady state, at equilibrium, or neither.
- • Isothermal, isobaric, isochoric, adiabatic closed, or open system is applicable or not
System: The air inside a hot air balloon
Process: The balloon floats, stationary, 1000 feet above the ground. The air in the balloon is maintained at a constant temperature.
E)
Identify the following system and process is,
- • steady state, at equilibrium, or neither.
- • Isothermal, isobaric, isochoric, adiabatic closed, or open system is applicable or not
System: A wood furnace and its contents
Process: Wood is piled inside the furnace. When the process begins, the wood is already burning and the furnace and its contents are at a uniform T = 300°F. At the end of the process, 10 minutes later, the temperature is still a uniform T = 300°F.
F)
Identify the following system and process is,
- • steady state, at equilibrium, or neither.
- • Isothermal, isobaric, isochoric, adiabatic closed, or open system is applicable or not
System: A section of a water pipe
Process: Water is flowing through the pipe at a constant flow rate and a constant, uniform temperature.
G)
Identify the following system and process is,
- • steady state, at equilibrium, or neither.
- • Isothermal, isobaric, isochoric, adiabatic closed, or open system is applicable or not
System: The water in a sink
Process: The process begins immediately after the faucet is turned off. The water is initially at 90°F, the ambient air is at 70°F. The process Continues for 24 hours, during which evaporation is negligible and no water is added or removed.
H)
Identify the following system and process is,
- • steady state, at equilibrium, or neither.
- • Isothermal, isobaric, isochoric, adiabatic closed, or open system is applicable or not
System: Your body
Process: You are stationary and immersed in bathwater at 98.6°F throughout the process.
