Water

QuestionAnswer
Water is made of ____ hydrogen atom(s) and ____ oxygen atom(s). 2 hydrogen 1 oxygen
Water molecules are polar. This means... water molecules have a positive and negative side -like a magnet.
The hydrogen side of a water molecule has a _________________ charge. positive
The oxygen side of a water molecule has a _________________ charge. negative
Adhesion makes water good at... picking up/grabbing dry polar material -Like dust
Adhesion and cohesion makes water travel up the "tubes" in plants, this is called ______________ _______________. capillary action
Cohesion is when ... water molecules are attracted to each other.
Adhesion is when... water molecules are attracted to other polar material/objects
High Specific Heat means... needing a lot of energy to change temperature
Water is called the universal solvent because... It is capable of dissolving more substances than any other liquid.
Water has a high specific heat and this makes water good at... keeping global temperatures consistent, keeping drinks cold, etc...
All things become more dense as they lose energy and cool down No. Most things do. Water is a rule breaker. It becomes less dense a when it is about to freeze!
What property of water makes it a rule breaker? cohesion
Water will slowly break down most materials, even rocks. This is because water is the ... universal solvent
The balloon with a little water in it did not pop when placed over a flame. This demonstrated water's property of ... high specific heat.
Ice floats on liquid water because it is ... less dense than liquid water ( rule breaker)
A stronger cohesive attraction of water molecules along the top area of water is called... surface tension
The positive and negative attractive force between two water molecules is called a _______________ bond. hydrogen
What temperature does liquid water freeze? 0 degrees Celcius or 273K
What temperature does frozen water melt? 0 degrees Celcius or 273K
Precipitation is... any form of water falling from the sky?
Is snow precipitation? Yes. It is a form of water falling from the sky!
What would happen if you put water on a non-polar substance? it would not adhere. It would roll right off. It would not stick or soak in.
Why is water called the universal solvent? A. It can dissolve anything given enough time B. It can dissolve more things than any other liquid C. It can solve universal problems D. It is dissolved by all other substances B
The amount of energy in Joules needed to heat one gram of a substance one degree Celcius. Specific Heat
Water is the freezing point of water? 273K 0 degrees Celcius
What is water's melting point? 273K 0 degrees Celcius
Rain drops form because of... cohesion.
Water has 4 distinct properties: These are... High Specific heat, Adhesion, Cohesion and Universal Solvent
