A
-cohesion (attraction between the same molecule)
-adhesion (attraction between different molecules)
caused by hydrogen bonding
applications: vascular transport in plants and surface tension
2
Q
Moderation of temperature (1/4 properties of water)
A
water has a high specific heat (takes a lot of heat energy to raise 1g of water’s temp 1 degree celsius)
caused by hydrogen bonding
3
Q
