WebAlmost every transfer of energy that takes place in real-world physical systems does so with efficiency less than 100% and results in some thermal energy. This energy is usually in the form of low-level thermal energy. Here, low-level means that the temperature associated with the thermal energy is close to that of the environment. WebFirst Law: T d S = d E − d W so d E = T d S + d W alternatively, you could use Q = m c Δ θ Where Δ θ is the temperature difference between the gas and the liquid. To use this in …
