10 de may. de 2024 · temperature, measure of hotness or coldness expressed in terms of any of several arbitrary scales and indicating the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature).
2 de may. de 2024 · We can define an additional variable called the specific heat ratio, which is given the Greek symbol “gamma” ( γ γ ), which is equal to c p divided by c v: γ = cp cv γ = c p c v. “Gamma” is just a number whose value depends on the state of the gas. For air, gamma = 1.4 for standard day conditions.
Hace 21 horas · Heat equation. Animated plot of the evolution of the temperature in a square metal plate as predicted by the heat equation. The height and redness indicate the temperature at each point. The initial state has a uniformly hot hoof-shaped region (red) surrounded by uniformly cold region (yellow). As time passes the heat diffuses into the cold region.
