Multiple Choice

In section 1 of the periodic table, what property do all of the elements have in common?

• They are all metalloids with a dull luster

• They are all metalloids with a shiny luster

• They are all metals with a dull luster

• They are all metals with a shiny luster

Multiple Choice

A mid-ocean ridge is created by what type of tectonic plate boundary?

• divergent

• convergent

• transform

Multiple Choice

Which cart has the HIGHEST kinetic energy?

• A

• B

• C

• D

• E

Multiple Choice

Which of the following answer choices correctly explains how thermal energy is transferred?

• Heat from the fire warms up the water in the pan causing the heat to rise and the cold to sink. This causes convections currents as the water continues to warm up. As the water heats up steam is produced which causes the handle to heat up due to conduction.

• Heat from the fire causes the water to warm up in the pan. The cold rises while the heat sinks causing conduction currents. After the conduction currents heat up, the steam causes the handle to heat up up due to convection.

• Convection currents from the fire cause radiation in the water which heats it up. Hot rises while cold sinks due to conduction currents. The conduction currents cause steam and the steam heats up the handle due to convection.

Multiple Choice

Multiple Choice

Three weights are placed on top of a table. The distance from the top of the table to the floor is 4 meters. The mass of the first weight is 2kg, the mass of the second weight is 4kg, and the mass of the last weight is 10kg. Which weight has the greatest amount of potential energy?

• weight 1

• weight 2

• weight 3

• all of the weights have the same amount of potential energy

Multiple Choice
