Be careful to distinguish between the concepts of heat and temperature. Heat is always energy in transit between bodies; temperature is the measure of the internal energy of a single body.

A. 对
B. 错

No system can take heat from a single heat reservoir (热源) and convert it entirely into work without additional net changes in the system or its surroundings.

A. 对
B. 错

The first law of thermodynamics is an expression of the principle of conservation of energy. It states that energy can be transformed (changed from one form to another), but cannot be created or destroyed.

A. 对
B. 错

Thermodynamics, science of the relationship between heat, work, temperature, and energy. In broad terms, thermodynamics deals with the transfer of energy from one place to another and from one form to another.

A. 对
B. 错

Thermodynamic equilibrium, in which there is no tendency for the state of a system to change spontaneously (自发地). 热力学平衡,其中系统状态不存在自发改变的趋势。

A. 对
B. 错

When the wave propagates (传播) in the medium, the kinetic energy and potential energy of the volume of elements (体积微元) have the same changing laws.

A. 对
B. 错

如果系统在始末两个平衡态之间经历的过程是无限缓慢的，则系统所经历的每一个中间状态都可以近似地看成是平衡态，我们将此变化过程称为 过程。

卡诺循环是由两个可逆 过程和两个可逆绝热过程组成的循环。

可以把热量从低温物体传到高温物体而不产生任何其他变化。 （ ）

A. 对
B. 错

提高低温热源的温度，降低高温热源的温度，可以提高卡诺热机的效率。 （ ）
