1982 Copper vs Zinc Penny
One way to tell is by the date. 1981 and prior years are copper. 1983 and future years are zinc. But I'll bet you mean how to tell the difference with 1982 pennies.
The only way to tell is by weight. The copper weighs about 3.11 grams and the zinc weighs about 2.5 grams. You need a very sensitive scale to measure these.
