How does vapour pressure of supercooled water compare with that of ice at the same temperature?
It would be lower.
In an activity20 grams of salt are dissolved in 70 grams of water. The water is then heated on a hot plate. When the water evaporates completelyhow much salt will be left?
If the water was pure and had no salt already mixed in it then the same 20 grams of salt would be left, as salt doesn't evaporates on the temperature at which water does evaporates.
What is the final temperature of water if a metal is dropped in to it?
This would depend on the temperature of the water before you add the metal and what type of metal it is. if its copper it absorbs heat fast and would not change the temperature much but if you dropped lead into it then it would have to absorb more heat making the temperature lower than the copper. There are too many variables to answer the question.
Does ice water or ice cubes cool lemonade faster?
If the initial temperature of the lemonade is equal for both the water and the ice then the cubes would cool lemonade faster because they have a lower initial temperature.
Would fevers run higher or lower if liquid water's specific heat were not so high?
Fevers would run higher if liquid water's specific heat were lower. The amount of energy need to raise our body temperature would be less. Although the body would still develop control mechanisms to regulate the temperature to prevent heat death of the cells.
How many grams water are in 100 milliliters of water?
The answer depends on the temperature, but at room temperature (20 deg C), 100 ml of water would have a mass of 99.82 grams.
What would be the final temperature when 250 grams of water at 100 degrees celsius is mixed with 525 grams of water at 30 degrees celsius?
The temperature would be that of water's boilng point od 100 degrees
What would be the mass of 134.63 ml of water?
At standard temperature and pressure, ml = grams for water, so at STP, 134.63 ml of water = 134.63 grams.
How does vapour pressure of supercooled water compare with that of ice at the same temperature?
It would be lower.
Does rain water boil at lower temperature than sea water?
Rain water would normally boil at a slightly lower temperature than sea water, assuming the rain water has fewer dissolved particles in it compared to sea water.
How would ice cubes lower the temperature of the water?
the temperature of ice cubes are lower than the temperature of the water around them. The heat energy from the water is used up in the process of melting the ice, so the water temperature drops.
In an activity20 grams of salt are dissolved in 70 grams of water. The water is then heated on a hot plate. When the water evaporates completelyhow much salt will be left?
If the water was pure and had no salt already mixed in it then the same 20 grams of salt would be left, as salt doesn't evaporates on the temperature at which water does evaporates.
How many grams are in 12 liters of water?
It depends upon the substance and the temperature. For water at room temperature the volume would be 0.0125L
How much would 50 ml water be in grams?
By definition, it weighs 50 grams. A litre of water weighs a kilogram.
Is If sea water has salt in it it will freeze at a lower temperature than fresh water is this sentence a hypothesis?
No. A hypothesis would be "As the gradient of salt in the water increases the freezing point would decrease"
How many ml in 37.5 grams of water?
37.5 ml. This varies with temperature. The above volume is at 4 degree C. At higher temperatures, water has less density and therefore the volume would increase. Unusually the water again becomes lighter at lower temperatures till it freezes at zero degrees C.
What would 1 liter of water have a mass under the conditions of standard temperature and pressure?
it would have a mass of 100grams ------------------------------------------------------------------------ One kilogram (oe 1000 grams)
