During an isothermal compression of an ideal gas, J of heat must be removed from the gas to maintain constant temperature. How much work is done by the gas during the process?
Guida verificata passo dopo passo1
Understand that during an isothermal process for an ideal gas, the temperature remains constant. According to the first law of thermodynamics, the change in internal energy (ΔU) is zero for an isothermal process.
Recall the first law of thermodynamics, which is given by the equation: ΔU = Q - W, where ΔU is the change in internal energy, Q is the heat added to the system, and W is the work done by the system.
Since the process is isothermal, ΔU = 0. Therefore, the equation simplifies to 0 = Q - W, which can be rearranged to W = Q.
In this problem, 410 J of heat is removed from the gas, which means Q = -410 J (since heat is removed, it is negative).
Substitute Q = -410 J into the equation W = Q to find the work done by the gas. This will give you the value of work done by the gas during the isothermal compression.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Isothermal Process
An isothermal process is a thermodynamic process in which the temperature of the system remains constant. For an ideal gas, this implies that any heat added to the system is used to do work, and any heat removed is equivalent to the work done on the system. This is described by the equation Q = W, where Q is the heat exchanged and W is the work done.

Entropy & Ideal Gas Processes
First Law of Thermodynamics
The First Law of Thermodynamics states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system on its surroundings. In an isothermal process for an ideal gas, the internal energy change is zero, so the heat exchanged is equal to the work done, i.e., ΔU = 0, thus Q = W.

Ideal Gas Law
The Ideal Gas Law is a fundamental equation that relates the pressure, volume, and temperature of an ideal gas through the equation PV = nRT, where P is pressure, V is volume, T is temperature, n is the number of moles, and R is the ideal gas constant. In an isothermal process, the temperature remains constant, so the product of pressure and volume remains constant as well.
