A simple, albeit slightly less useful example perhaps, is when a foundry, or individual metalworker, liquefies metal such as iron, aluminum, or steel so that it can be mixed in with specific forging agents or transferred around a workplace.
In general solids are easier to transport than liquids, but the above metal example is a valid one and the only other one that comes to mind is that of concrete. It is mixed as a liquid and transported as such, but then sprayed or laid down to dry and form a solid surface or filler. <span />
Explanation: Chemicals in the original manufacturer’s container that have been recently purchased from a supplier will most likely contain hazard information in the form of warnings and pictograms. Older manufacturer’s chemical containers may have alternative labeling schemes that provide essentially the same information as the new labels.
253.15
The temperature T in degrees Celsius (°C) is equal to the temperature T in Kelvin (K) minus 273.15:
T(°C) = T(K) - 273.15
...if you use magnetso this is a mixture
p/s: or this is physical process
sorry if I'm wrong
A balanced the reaction of lead with hydrochloric acid:
Pb(aq) + 2HLC (l) → PbCl2(aq) + H2(g)
