A group of scientists is conducting an investigation to study the conductivity of perovskite. At which temperature do they need to perform the experiments for perovskite to conduct electric current?

t=1980C AND T>1980C

Explanation:

answer; i believe that the correct answer is (c) explore the outer planets; / plz check good luck

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
