What suubstance will react with water at room temperature and pressure to produce hydrogen?
Sodium reacts with water at room temperature (even at lower ) and produce hydrogen gas , 2Na + 2H2O = 2NaOH + H2
Why water boil faster at higher pressure than the lower pressure from the aspect of the water molecule?
water boil`s faster at lower pressure at higher pressure the temperature needs to be higher for instance at 16 bar [don`t know the psi for that ]the temp is about 220 degrees Celsius
When 2 basic subunits come together form a large macromoleculewhat other molecule is also produce?
Produce water
What conditions are gases most soluble in water?
The solubilty of gases in water is increased at lower temperatures and higher pressures.
How does changing temperature or pressure affect the solubility of gas in water?
As temperature (of the solvent) decreases and pressure (of the gaseous solute) increases the solubility of gases in water will increase.

What 3 factors affect the density of sea water?
Temperature, pressure, and common ion effect
What will warm water molecule do in a lake?
High temperature.
How can your body heat water in a swimming pool?
If the temperature of the water is less than your body temperature, then heat will be transferred from the warmer body to the colder body of water. The molecules in your skin vibrate because they are warm. When a water molecule touches a warm vibrating skin molecule, some of the heat energy in the skin molecule is transferred to the water molecule, warming the water.
Is a polar molecule is a molecule with the ability to resists changes in temperature?
A polar molecule is a molecule with slight opposite charges. Water is a polar molecule which means that each water molecule is attracted to other water molecules which accounts for waters surface tension or cohesion.
When 2 basic subunits come together form a large macromoleculewhat other molecule is also produce?
Produce water
What is the boiling point of a single water molecule?
Boiling temperature makes sense only in macroscopic world. Temperature itself is a macroscopic quantity, However ,by use of kinetic theory one can show that energy of a molecule(microscopic quantity) is proportional to the temperature of the surroundings(macroscopic quantity). Boiling temperature is thus a temperature at which the molecule gains sufficient energy to overcome the coulomb barrier between its molecules of the bulk. Hence boiling temperature of a single water molecule is meaningless ! *********
What is the temperature when boiling water starts to evaporate?
There is no such temperature to start evaporating. Even in the room temperature or in a refrigerator, water does evaporate. When a particular water molecule absorbs adequate energy (let's say from heat), there will be a phasechange in that molecule from liquid to gas, and it's called evaporation.
How water temperature affects the structure?
The structure of the molecule remain unchanged.
Can you boil the water at room temperature?
yes,at room temperature by decreasing the pressure we can boil the water.
What is the reaction of graphite and water?
Nothing, It will sink but it won't react with water at room temperature. You have to heat graphite to something like 800 degrees Celsius to react with water at that temperature it will react with steam to produce carbon monoxide and hydrogen gas.
