A mixture is a combination of materials that are combined solely by physical processes. There are two types of mixtures heterogeneous and homogeneous.
Homogeneous mixture is a mixture that has uniform composition of their components. Composition of a substance means color, shape, size, weight etc.
Heterogeneous mixture is a mixture that does not have uniform composition of their components.
Steel is an alloy which is a combination of iron and carbon. The composition of iron and carbon is not uniform, so the mixture is a heterogeneous mixture.
Answer:A 2.2kg block of ice slides across a rough floor. Its initial velocity is 2.5m/s and its final velocity is 0.50m/s. How much of the ice block melted as a result of the work done by friction? (Latent Heat of water is 3.3*10^5J/kg)
