Three different rocks that each weigh 50 grams are put out in the sunlight. After two hours, they are all at the same temperature. Pick the true statement.

All rocks have same thermal conductivity.

Explanation:

Rocks are heated with the sunlight exposure. Different types of rocks have different thermal conductivity. The heat energy of the rocks is measure in Joules. The size and thermal conductivity of the rocks is important property which determines their heating capacity.

the dependant variable is spilled water

the independent is the heat
