Physical and Chemical Changes Major- 5th Grade

What is the key difference between a physical and chemical change?

• Physical changes always create new substances

• Chemical changes produce matter with different properties

• Physical changes always involve temperature shifts

• Chemical changes only happen in liquids

Which of the following is a sign of a chemical change?

• Cutting paper into smaller pieces

• Pouring water from one glass to another

• Formation of a new gas

• Changing container shape

The law of conservation of mass means:

• Matter can be destroyed during reactions

• Matter is created during chemical changes

• Matter is neither created nor destroyed

• Only gases can change form

In a solid, particles are:

• Far apart and moving quickly

• Tightly packed and vibrating in place

• Sliding freely past each other

• Randomly scattered

Temperature measures:

• The color of an object

• The weight of particles

• Movement of particles in an object

• The container's size

When energy is added to matter, particles:

• Stop moving completely

• Move more slowly

• Move more quickly

• Disappear

Condensation is an example of:

• Adding energy to matter

• Removing energy from matter

• Creating new particles

• Changing container shape

A liquid can:

• Maintain a fixed shape

• Be poured between containers

• Have tightly packed particles

• Remain completely still

In a gas, particles are:

• Tightly packed together

• Completely stationary

• Far apart and moving easily

• Fixed in one position

Which state of matter has no definite shape or volume?

• Solid

• Liquid

• Gas

• Plasma
