Q=mc(delta T)
m= Q/ c(delta T)
m= 1200 J / (4.19 J/kg C) (15-10)
m= 57. 28 kg
Speed = Distance divided by time
Speed = 150 km / 7200 s
Speed = 1 km / 48 s
In the presence of an emulsifying agent, a mixture of oil and water becomes a colloidal dispersion.
Colloidal dispersion <span><span>otherwise </span>colloid</span><span> is </span><span>a system, in which discrete particles, droplets or bubbles of a dispersed phase (in this case oil), whose size at least in one dimension is in the range from 1 to 1000 nm are distributed in the other, usually continuous phase - dispersion medium (in this case water) differing from the dispersed phase in composition or state of aggregation.</span>
