Water Flashcards
Water is a ______ molecule
Polar
Why is water a polar molecule?
Due to the uneven distribution of charges in the molecule
State the why there is an imbalance
Hydrogen atoms are partially positive whereas oxygen atoms are partially negative due to electronegativity. This causes one end of the molecule to be more positive than the other.
Water is a polar _______
Solvent
Why can other substances dissolve in water?
Due to most substances being polar, these substances can dissolve in water
What is one function of water?
To transport many biological molecules
Why does water have a high specific heat capacity?
The atoms in the water molecule are bonded by hydrogen bonds which is a relatively strong type of bonding.
What is specific heat capacity?
It is the heat energy needed to raise 1kg of a molecule to 1 degree Celsius
What will happen due to water having a high specific heat capacity?
A lot of energy will be required to increase the temperature of water. This minimises the temperature in the living things around it.
