Water Flashcards
why is water a polar molecule
The electrons are shared unequally within the bonds that hold a water molecule together.
why is water a good solvent?
water is a good solvent because it can form hydrogen bonds and other other polar molecules or charged ionic conpounds
why is water referred to as a “universal solvent”?
Water dissolves more substances than any other liquid.
What is an advantage of water being a good solvent?
Blood consists mostly of water which is able to dissolve hydrophilic molecules such as glucose, ions and some amino acids.
Why has water got a high latent heat of evaporation?
Because a lot of energy is used to convert water from a liquid to a gas.
What is an advantage of water having a high latent heat of evaporation?
Makes us feel cooler when we sweat, since the evaporation of water from our skins surface takes a lot of heat energy with it
Why does water have a high specific heat capacity?
All those hydrogen bonds within water are great at absorbing energy, which means you have to add a lot of it to heat water up.
Why is a high specific heat capacity of water useful for marine life?
Bodies of water are fairly resistant to changes in temperature, making it a stable habitat in which to live.
