Velocity is a physical vector quantity The units associated with velocity is important in physics. Learn about the SI unit of velocity, formula and other common units.
where m and cp are the mass and the specific heat of Al, and QAl - latent is the latent heat of melting for aluminum, 405 kJ/kg. A similar formula is used for Si except that the enthalpy of fusion ΔHSi−AlF is used instead of the latent heat of melting, and the required heat...
protection of the melt from its environment (as for instance in an enclosed low-pressure casting unit); 3. when undisturbed, the melt may continue to be protected from the environment by its oxide and create little additional surface oxide by reaction with water vapour or hydrocarbon gases with...

unit of heat? Heat:Heat flows from one object to another object if there is a difference between the temperature of the objects. It flows from the object at a higher temperature to the object at a lower temperature. It is usually expressed in J(joules) and cal(calories).Answer...
It is worth mentioning that in these experiments, Tmin and Tg are the minimum and maximum temperature of the undercooling peak (Fig. 2). Tmin is the point where the latent heat of fusion is given off and Tg is the point at which the steady growth state is reached. The difference ...
