Is talc and water a colloid?

Talc is not soluble in water, but it is slightly soluble in dilute mineral acids. In any case, solving it will keep intact its structure. This is naturally true for the case of silicates, which are characteristics by their insolubility.

A is milk in water, actually is does not have to be in water since milk already is a mixture of fats and water. ... A colloid is just a mixture where a substance of dispersed insoluble particles is suspended throughout another substance. Chalk powder is very little soluble in water therefore this will form an suspension.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
