    It’s because the times aren’t the same. Maybe same unit but different context so they can’t be canceled.

    It’s like saying you work 8 Hours/day (Eight hours per day). Both are units of time, but their context is different and their combination forms a new meaning beyond the units.

    1 KWh is using 1KW for one hour. Because of demand pricing the time you use that KW is important. Like in terms of energy grid using a whole ton of power for one minute vs same total over a long time is different and important dispite being the same amount of energy.

    Edit: some phrasing


  • Could be steel rims. Engine blocks are typically Aluminium which have about half the melting point of Steel at only around 600C depending on alloy, which is pretty low in the metals world.

    Rims are also typically Aluminium but they are clearly not as melted so could be steel rims or the fire was not as concentrated there (core of the car burned out while the outside was bit cooler)

    Edit: The molten material could be from even lower melting point Al alloys (High in Silicon or Magnesium). Cars also can use some high Magnesium alloys that can have even lower melting point.
