Bars are set up from a heat source to a room temperature counter. What will be observed?

• Heat will move through all materials at the same speed

• Metal will conduct heat to the room temperature counter most quickly

• The cool from room temperature side will conduct through the metal more quickly to the heat

• Wood will conduct heat more quickly to the room temperature side.

When 1 gram of water is evaporated in a closed container, the volume increases but mass remains constant. Why?

• The number of atoms remains constant

• The pressure on the water remains constant

• The distance between the water molecules remains constant

• The temperature of the water remains constant.

What is in the bubbles of boiling water?

• Heat

• Air

• Hydrogen and Oxygen

• Water Vapor

When comparing the SAME substance, which conclusion is supported by the mass, volume, & density measurements in the table?

• When the mass is increased there is a change to the density

• When mass is decreased, there is no change to the volume

• when mass is increased, there is a change to the volume

How can scientists determine one substance from another?

• Run complex chemical tests

• Find physical properties like density and melting point

• Try to join substances to see how they combine

• Look at color and state

Why did scientists create the periodic table of elements?

• They found patterns in the physical properties & arranged them in groups

• They added new elements by date discovered

• They grouped them by phase at room temperature

• They determined how much was on Earth and put them in groups that way

Two students observed phase change of water as heat was added. The observed the water go from

• ice to water vapor to water

• water to water vapor to ice

• water vapor to water to ice

• ice to water to water vapor

• move slower

• move faster

• become something new
