Fluids and Thermodynamics

Fluids and Thermodynamics. Fluids Fluids are substances that can flow , such as liquids and gases, and even a few solids. In Physics B, we will limit our discussion of fluids to substances that can easily flow, such as liquids and gases. D = m/V D: density (kg/m 3 ) m: mass (kg)

THERMODYNAMICS AND ENERGY

Lecture # 2. THERMODYNAMICS AND ENERGY. The name thermodynamics stems from the Greek words therme (heat) and dynamics(power), which is most descriptive of the early efforts to convert heat into power. One of the most fundamental laws of nature is the conservation of energy principle.
