Lecture 4: Heat transfer
... Density is defined as mass per unit Volume. As the fluid is heated the Volume increases, the mass is constant therefore the density decreases. Hot fluids are less dense than cold fluids and will rise therefore convection currents (circular currents or movement within a fluid) due to different densit ...

... ∆U = Q + W The change in internal energy of a system comes about because of heat added to the system Q, plus the work done on the system. Heat and work represent energy in transit and are not thermodynamic state variables. Energy is a thermodynamic state variable. In thermodynamics the only two ways ...
