Exam Review

Anything that has mass and takes up space

• Mass

• Volume

• Weight

• Solid

You find the density of an object to be 2 g/mL. Finding this property of the object did not require you to change the atomic identity of the object. What do we call this?

• A Chemical Property

• A Physical Property

• An Molecular Property

You mix one substance with another and notice it gives off heat to test a property. This shows that the substance has changed form, what kind of property have you tested for?

• Chemical Property

• Physical Property

• Molecular Property

This subatomic particle has a positive charge

• Neutron

• Proton

• Electron

• Quasar

This is a pure substance made of only one type of atom

• Molecule

• Element

• Protist

• Proton

This state of matter has definite shape and volume. The particles are very close together and do not move past one another

• Solid

• Liquid

• Gas

In this state of matter particles are close together, but move freely and 'slide' past one another

• Solid

• Liquid

• Gas

This is the ability to cause change

• Energy

• Motion

• Potential

• Nuclear

Electromagnetic energy (light) can change form into electrical energy in a solar panel. This is an example of:

• Energy Transformation

• Energy Loss

• Energy Exchange

A "Newton's Cradle" (see image) will eventually stop moving. However, the energy was not destroyed, it was just turned into heat and sound energy. What scientific statement explains this?

• The Law of Motion

• The Law of Gravity

• The Law of Conservation of Energy

• The Law of Kinetic Energy
