WebA gas is found to obey the law P 2 V = constant. The initial temperature and volume are T 0 and V 0 . If the gas expands to a volume 3 V 0 then: WebThe gas absorbs heat Q h Q h from the heat reservoir and is allowed to expand isothermally, doing work W 1. W 1. Because the internal energy E int E int of an ideal gas is a function of the temperature only, the change of the internal energy is zero, that is, Δ E int = 0 Δ E int = 0 during this isothermal expansion.

WebThere is no change in the internal energy of an ideal gas undergoing an isothermal process since the internal energy depends only on the temperature. Is it therefore correct to say that an isothermal process is the same as an adiabatic process for an ideal gas? Explain your answer. Show Solution Does a gas do any work when it expands adiabatically? WebAn ideal gas expands quasi-statically and isothermally from a state with pressure p and volume V to a state with volume 4V. How much heat is added to the expanding gas? 41. As shown below, if the heat absorbed by the gas along AB is 400 J, determine the quantities of heat absorbed along (a) ADB; (b) ACB; and (c) ADCB. 42. WebCorrect option is B) An isothermal process is a change of a system, in which the temperature remains constant: ΔT = 0. In other words, in an isothermal process, the value ΔT = 0 and therefore the change in internal energy ΔU = 0 (only for an ideal gas) but Q ≠ 0, while in an adiabatic process, ΔT ≠ 0 but Q = 0. hcbs services new york
