Foundations Practice 1

A student classifies several objects. The classification system should be based on

• hypotheses

• observations

• interpretations

• inferences

The primary purpose of a classification system is to enable people to

• organize observations in a meaningful way

• extend their powers of observation

• make measurements that are very accurate

• eliminate inaccurate inferences

A centimeter is 0.01 meter. This measurement can also be expressed as

• 1 × 10² m

• 1 × 10⁻¹ m

• 1 × 10⁻² m

• 1 × 10² m

The circumference of the Earth is about 4.0 × 10⁴ kilometers. This value is equal to

• 400 km

• 40,000 km

• 400,000 km

• 4,000 km

Which one of the following statements about a mineral sample found in a field in New York State is most likely an inference?

Which one of the following statements made during a weather report is most likely an inference?

• The current barometric pressure is 29.97 in.

• The high temperature for the day was recorded at 2 p.m.

• Hot and humid conditions will continue throughout the week.

• The record low temperature for this date was set in 1957.

A pebble has a mass of 35 grams and a volume of 14 cubic centimeters. What is its density?

• 2.5 g/cm³

• 4.0 g/cm³

• 490 g/cm³

• 0.4 g/cm³

A mineral sample is found to have a density of 3.0 grams per cubic centimeter. It is then broken into two pieces, with one piece twice as large as the other. The smaller of the two pieces will have a density of

• 1.0 g/cm³

• 1.5 g/cm³

• 6.0 g/cm³

• 3.0 g/cm³

Water has the greatest density at

• 4°C in the liquid phase

• 0°C in the solid phase

• 4°C in the solid phase

• 100°C in the gaseous phase
