第十五届全国中学生物理竞赛预赛第七题:1mol理想气体缓慢地经过了一个循环过程,在P-V图中这一过程是一个椭圆,如图1所示。已知此气体若处在与椭圆中心O′点所对应的状态时,其温度为T_0=300K。求:整过循环过程气体的最高温度T_1和最低温度T_2各是多少?
The fifteenth session of the National Physics Contest Preliminaries seventh question: 1mol ideal gas slowly through a cycle, the P-V diagram of this process is an ellipse, as shown in Figure 1. It is known that this gas has a temperature of T_0 = 300 K if it is in a state corresponding to the O ’point of the center of the ellipse. Seeking: Throughout the process cycle the maximum temperature of the gas T_1 and the lowest temperature T_2 each is how much?
