What is specific heat capacity?

• The temperature of our classroom

• The amount of heat required to change the temperature of an object

• The amount of heat an object can hold before it burns

Cohesion makes

• water molecules stick to other water molecules

• water molecules stick to other polar substances

Adhesion makes

Capillary action uses both

• surface tension and adhesion

• surface tension and cohesion

• adhesion and cohesion

• Snapchat and Tik Tok

Why does water expand when it freezes even though most liquids contract when they freeze?

• because its chemical bonds are weak

• because it is the universal solvent

• because of its crystalline structure

• because of its covalent bonds

What is density?

• The ability to dissolve

• Amount of mass in a specific volume

• Genius level intelligence

• Science is awesome!
