500cm3 of ideal gas at 40 degrees Celsius and 200kpa absolute is compressed to 250cm3 and cooled to 20 degrees Celsius.What is the final absolute pressure?
Assuming the amount of gas remains constant, we can use the ideal gas law to calculate the final absolute pressure. The initial pressure (P1) is 200 kPa and the final volume (V2) is 250 cm3. The initial temperature (T1) is 40 degrees Celsius or 313.15 Kelvin, and the final temperature (T2) is 20 degrees Celsius or 293.15 Kelvin. Using the equation (P1 * V1) / T1 = (P2 * V2) / T2, we can solve for the final absolute pressure (P2), which is approximately 400 kPa.
A sample of Xenon gas at 20degree Celsius and 0.570 ATM is cooled to a pressure of 0.100 ATM If the volume remains constant What is the final Celsius temperature?
It would be -221.7 deg C.
Do any matter expand when cooled and contract when heated?
Sort of. In the temperature range of 0-4 Degrees Celsius water contracts when heated and expands when cooled. Outside of this temperature range it behaves normally.
How much energy is released when 42.5g of aluminum vapor are cooled from 4750 degrees Celsius to 25 degrees Celsius?
q = (42.5 g)(0.902 J/gC)(25o C - 4750o C) = - 1.8 X 105 Joules ====================negative can be ignored for absolute value, but remember the direction the heat is going.
What change happens to liquid water when it is cooled to 0 celsius?
It freezes.
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
A container of oxygen at 22 degrees Celsius and 740mm Hg is cooled to -22 degrees Celsius What is the new pressure of the gas?
Formula:P1 P2---- = ----T1 T2P1= 740 mm HgP2= UnknownT1= 22°C= 295 KT2= -22°C= 251 K740 / 295 = P2 / 251P2= 630 mm Hg
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.
