(c) Alloys are homogenous mixtures.
(d) Solution is a heterogeneous mixture.
Which of the above statements are correct?

(d) Solution is a heterogeneous mixture.
Which of the above statements are correct?
The correct option is A (a), (b) and (c)
a. An increasing or decreasing temperature doesn't affect mass. Mass is the amount of matter in an object whereas temperature is the human sense of kinetic energy of matter. Thermal energy is very, very, very small, so no, it is not measurable as mass.
b. Plasma is the fourth state of matter. Plasma is an ionized gas, a gas into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species, ions and electrons, to coexist.
c. An alloy is a homogeneous mixture of 2 or more metals or metal with 2 or more semi-metals.
d. It is homogeneous because the additions take place in the liquid state, so the atoms mingle with each other and mix thoroughly.
