Question

to find the rocks density, matt needs to determine the rocks mass and volume. the best way to determine the mass of this sample is to ____________. a. increase the temperature until the substance begins to melt b. place the sample on a triple - beam balance c. examine the sample under an ultraviolet light d. place the sample in a graduated cylinder with water

Explanation:

A triple - beam balance is a common instrument used to measure the mass of an object. Increasing temperature measures melting point, examining under UV light can reveal fluorescence properties, and placing in a graduated cylinder with water measures volume by displacement.

Answer:

B. place the sample on a triple - beam balance
