A group of students is conducting a density experiment with two blocks. Block 1 has more mass and less volume than Block 2. Based on this information, the student can correctly conclude that
Block 1 has a higher density than Block 2.
both blocks have densities less than water’s density.
both blocks have densities greater than water’s density.
Block 1 has a lower density than Block 2.
