6th Grade Unit 2 Test 1 review

Insulation is a material that:

• Speeds up the transfer of heat

• Conducts heat quickly

• Slows down the transfer of heat

• Makes objects cooler

What is the primary function of insulation in a container?

• To add weight to the container

• To change the color of the container

• To slow down temperature changes inside the container

• To make the container more expensive

Which of the following is a good insulator?

• Metal

• Glass

• Copper

• Foam

Why is it important to understand how insulation works in a cup system?

• To make cups look more attractive

• To ensure drinks remain at the desired temperature longer

• To make the cup lighter

• To change the taste of the drink

If a cup is left in a cold environment without insulation, what is likely to happen to a hot drink inside?

• The drink will stay hot

• The drink will cool down quickly

• The drink will become hotter

• The drink will remain unchanged

What is the relationship between temperature change and heat transfer?

• Temperature always increases when heat is transferred.

• Temperature change is when a material gains or loses heat.

• Temperature change can only happen when heat is lost.

• Temperature change happens only when the material is in the sun.

What is Scientific Inquiry?

• Doing laboratories

• Drawing a model to explain something.

• Collecting evidence of a phenomenom

• Asking questions and conducting experiments to investigate observations.

Kinetic energy is the energy an object has due to movement.

• True

• False

When water is heated, the water molecules move faster and spread out more.

• True

• False

When water is cooled, the water molecules move slower and get closer together.

• True

• False
