How does the specific heat of water compare to that of metal?

• Water has a higher specific heat

• Metal has a higher specific heat

• They have the same specific heat

• Specific heat is not a property of materials

DOK Level 2: Skill/Concept

What happens to most materials when they are heated and why?

• They contract because molecules lose energy

• They expand because molecules move faster and spread out

• They do not change because temperature has no effect on materials

• They dissolve into a liquid form

Why do engineers use insulators in building construction?

• To allow heat transfer easily between the inside and outside

• To prevent heat transfer, keeping buildings warmer in winter and cooler in summer

• To make the buildings heavier and more stable

• To increase the electrical conductivity of the building
