PROPERTIES OF WATER

What does cohesion refer to in the context of water?

• Water sticking to other surfaces

• Water changing states

• Water resisting temperature changes

• Water molecules sticking to each other

Adhesion is the ability of water to:

• Stick to other surfaces

• Change its state

• Resist temperature changes

• Evaporate quickly

What does specific heat capacity measure?

• How quickly something cools down

• How much heat it takes to raise the temperature of a substance

• How cold something can get

• How much water a substance can hold

How does cohesion contribute to the formation of water droplets? (think of the lab experiment)

• By making water molecules repel each other

• By making water molecules stick together

• By increasing water temperature

• By causing water to evaporate quickly

Adhesion is crucial for:

• Cooling down substances

• Sticking water molecules together

• Allowing water to climb in narrow tubes

• Preventing water from freezing

Water's high specific heat capacity means that it:

• Cools down quickly

• Warms up quickly

• Resists temperature changes effectively

• Can't hold much heat

• By making water molecules repel each other

• By making water molecules stick together

• By increasing water temperature

• By causing water to evaporate quickly

• Speed of ocean currents

• Types of fish in the ocean

• Frequency of rainstorms

How is cohesion related to surface tension?

• Cohesion weakens surface tension

• Cohesion and surface tension are unrelated

• Cohesion strengthens surface tension

• Cohesion causes water to evaporate

How does the high specific heat capacity of water assist polar bears in regulating their body temperature?

• By allowing them to cool down rapidly

• By preventing them from getting too hot

• By enabling them to retain body heat for a long time

• By reducing their dependence on body heat
