Properties of Water Test 1

What does 'nonpolar' mean?

• Separation of charge

• No separation of charge

• High surface tension

• Capillary action.

Adhesion allows water to stick to other types of molecules, enabling what process in plants?

• Photosynthesis

• Capillary action

• Respiration

• Transpiration

High specific heat of water means it takes a lot of energy to change its temperature. This property helps water to:

• Freeze quickly

• Act as a buffer to climate changes

• Evaporate easily

• Dissolve substances.

Water is less dense as a solid, which allows ice to float on liquid water. This is important because:

• It makes water a universal solvent

• It allows life to exist under frozen surfaces

• It increases water's surface tension

• It decreases water's specific heat.

Water is known as the universal solvent because: A) It dissolves more substances than any other liquid B) It has a high specific heat C) It is less dense as a solid D) It has high surface tension.

• It dissolves more substances than any other liquid

• It has a high specific heat

• It is less dense as a solid

• It has high surface tension.
