Formula:
P1 P2
---- = ----
T1 T2
P1= 740 mm Hg
P2= Unknown
T1= 22°C= 295 K
T2= -22°C= 251 K
740 / 295 = P2 / 251
P2= 630 mm Hg

How many grams of KCl remain in solution at 20 degrees celsius when a solution containing 80g of KCl in 200g of water at 50 degrees Celsius is cooled to 20 degrees Celsius?
32 g KCl
What pressure would you expect in a rigid container of 0 centigrade gas if you cooled it by 273 centigrade?
You can never get to -273 C or 0 Kelvin. But if you could, the pressure would be zero
What happens to water when it reaches 0 degrees celsius?
At normal atmospheric pressure, water begins to freeze (turn into solid ice) at zero degrees centigrade. ACTUALLY: If saturation occurs at temperatures between 0 degrees Celsius and -4 degrees Celsius , the surplus water vapor invariably condenses into SUPERCOOLED WATER(water having a temperature below the melting point of ice, but nonetheless existing in a liquid state). Ice does not form within this range of temperatures.
What temperature in centigrade does water freeze?
"Pure" water freezes at a temperature of 0 (zero) degrees Celsius.This is for normal atmospheric pressure. The Celsius scale was defined by the freezing and boiling points of water, with 100 equal intervals (degrees) between them.Melting vs Freezing PointIce melts at 0° Celsius, this is how it is defined. Water can be cooled below 0°C if it contains ions in solution. Pure water will begin to freeze at 0°C, but requires the removal of additional energy (heat of fusion) to change phase into crystalline ice. Zero degrees 0°cif you're saying celsius the its 0 degreesFreezing point- 0 degrees C Depends on the pressure and anything dissolved in the water. ANYTHING FROM -18C - 4 Cwater freezes at 0 degrees Celsius0 degrees C. Boils- 100 degrees C.At about 0 degrees Celsius.
What is the lowest degrees in Celsius?
Absolute Zero, or zero Kelvin, = -273.15 degree Celsius That's it. Coldest theoretical temperature. All molecules in substance have stopped moving so no kinetic energy in molecules and so no heat energy in substance.The lowest temperature in degrees celsius is -273.15 C
When water at 4 degrees Celsius is cooled it does it contract?
No. When water is cooled it contracts up to 4 degrees Celsius and then it begins to expand till 0 degrees Celsius. This is called the anomalous expansion of water.
What would happen to the pressure if you cooled down the container?
The pressure inside the container would decrease.
When a sample of gas is cooled in a closed container the pressure inside the container?
increases......
How does nitrogen change into liquid nitrogen?
It has to be cooled to below -196 degrees Celsius or -321 degrees Fahrenheit.
What will happen as the temperature is gradually cooled at 10 degrees celsius?
It will gradually drop to below 10 degrees.
What 5 things expand when cooled?
water True, but only in the range 4 degrees Celsius to zero Celsius.
How many grams of KCl remain in solution at 20 degrees celsius when a solution containing 80g of KCl in 200g of water at 50 degrees Celsius is cooled to 20 degrees Celsius?
32 g KCl
When a container of gas is cooled what happens to the gas inside?
Gas pressure decreases when cooling down a closed container.
Can a car engine exceed 500 degrees?
No. Car engines are cooled by water (under pressure), so they run at or aground 100 degrees Celsius. Of cause in the combustion chamber and at the exhaust temperatures are much higher.
What state change occurs when the gas is cooled to 100 degrees Celsius?
gas to a liquid
How to convert gaseous carbon dioxide to solid carbon dioxide?
The same as most substances, CO2 must be cooled and put under increased pressure to become a solid. At one atmosphere, CO2 must be cooled to a temperature of -78.5 degrees Celsius to solidify. At height pressures CO2 solidifies at higher temperatures, however solid CO2 never exists at a temperature above -56.4 degrees Celsius.
Why are cans in a retort cooled under pressure?
A retort pouch (laminated plastic-metal) is cooked at 240-250 degrees F under high pressure in an autoclave. it is not cooled under pressure.
