This is a nice question to work with. For a gas, the product (P x V) is proportional to 'T'. ('Pressure', 'Volume', 'Temperature') But we have to be careful, because the temperature has to be referenced to absolute-zero. For Celsius, that's -273.15. -50 C = 223.15 K 200 C = 473.15 K The change in absolute 'T' was (473.15 / 223.15) = 2.12 times as great (rounded) So the product (P x V) must also become 2.12 times as great. If 'P' remains constant, then 'V' must become 2.12 times as great = (5 x 2.12) = 10.602 liters. According to the gas law pV=nRT, given as isobaric situation Volume is directly proportional to temperature. v1/t1= v2/t2 => v2=v1*t2/t1 v2= 5*(200+273)/(-50+273) v2=5*473/223 v2= 8.663 L

136.73 mL
Is a temperature in degrees Fahrenheit proportional to its equivalent temperature in degrees celsius?
Proportional, in mathematical terms, means that the ratio remains constant no matter what. But Celsius and Fahrenheit's ratio does not remain constant: 1 degree Celsius is equal to 33.8 degrees Fahrenheit, and 2 degrees C equals 35.6 degrees F. If you divide 35.6 by 2, it should equal 33.8, but since it does not, then therefore Celsius is not proportional to Fahrenheit.To convert F to C:F = C x 9/5 +32It is the plus 32 that makes the temperatures not proportional.C = (F - 32) x 5/9
A 6.5 l sample of nitrogen at 25 degree celsius and 0.76 ATM is allowed to expand to 13.0 l the temperature remains constant what is the final pressure?
If it is an ideal gas, then 0.409 ATM. The governing equation is pv=nrt. Everything on the right side of the equation is constant so pv = constant. Therefore: p1v1 = p2v2 (0.7atm)(3.8L) = p2(6.5L) p2 = 0.409 ATM
What happens to boiling water if the pressure increases or decreases?
water boils when the vapour pressure becomes equal to the external pressure. So if we increase the pressure, the rate of boiling will increase. Think of the vapor pressure as the pressure that is needed to force a bubble to the surface.it lowers
A sample of oxygen occupies 1.00 L If the temperature remains constant and the pressure on the oxygen is tripled what is the new volume?

What is the volume of a quantity of gas at 152 degrees celsius if its volume is 262ml at -35.0 degrees celsius the pressure remains constant?
468ml

What portion of the atmosphere where temperature remains fairly constant?
It is the stratosphere atmospheric zone where the temperature stays fairly constant, at -60 degrees Celsius. The stratosphere layer contains the ozone layer.
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.
What is water at 20 degree Celsius?
It just remains as water. The freezing point of water is 0 degrees Celsius, while the freezing point is 100 degrees Celsius. Therefore at 20 degrees Celsius, there is no change in state and it just remains as water.
What happenes to the temperature of a material when it changes state?
Usually it remains constant. For instance when you boil water and it turns into steam, the temperature of the boiling water remains at 100 Degrees Celsius throughout the process.
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.
What is the melting point of pure ice?
The boiling point of pure water is typically about 100 degrees Celsius. This value can vary based on factors such as pressure. Additionally, impurities in a sample of water can alter its boiling point.
How hot must the air in a balloon be heated if initially it has a volume of 750 L at 20 degrees celsius and the final volume must be 1000 L?
The way to keep this simple is to assume that the pressure in the balloon remains constant throughout the operation. The only trick to this whole thing is to understand that-- At constant pressure, volume is directly proportional to temperature.Volume2/Volume1 = Temperature2/Temperature1-- 'Temperature' means absolute temperature ... Kelvin, or (Celsius + 273).? The initial temperature of 20 C is absolute temp of 293 K.If the pressure remains constant, thenAbsolute-temp2 = Absolute-temp1 x (Volume2/Volume1) = 1,000 x 293/750 = 3902/3 K.°Celsius = Absolute - 273 = 117 2/3 ° C.
A quantity of an ideal gas is 0 degrees Celsius Another ideal gas is twice as hot What is the temperature?
Since 0 degrees Celsius equals 273 degrees Kelvin, then air that is twice as hot would be equal to 546 degrees Kelvin, which when converted back to Celsius is equal to 273 degrees Celsius. The natural urge is to double the Celsius temperature, let's say it was 5 degrees Celsius, then you'd probably want to double it to 10 degrees Celsius, however, that isn't correct. True temperature is measured in Kelvins, so you must convert to Kelvin to find out the true temperature conversion. Hope this answers the question.

What is the pressure of the air in ATM in the lungs when the gas expands to 195.0 ml at a body temperature of 37 degrees C and the amount of gas remains constant?
You have not given enough information to answer this question. pressure depends on volume temperature and the amount of gas. just stating that the amount of gas remains constant is not enough information.
