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 happens to the internal energy of an ideal gas when it is heated from 0 Celsius to 4 Celsius?
It depends on the circumstances, if the gas is in a flexible container and the pressure exerted on the gas is constant throughout the heating the it's volume will increase. This is governed by Charles law V1/T1=V2/T2 (here the temperatures must be expressed in Kelvin O0C = 273 K and 1000C = 373K) On the other hand, if the gas is in a container that can't expand, such as a steel cylinder, then it's volume will remain constant and it's pressure will increase, this is governed by Amonton's Law which is very similar to Charles' Law but deals with the relationship of pressure and temperature P1/T1=P2/T2 again the temperatures must be expressed in Kelvin for the calculations to be accurate.
The pressure acting on 60 cubic meters of gas is raised from 236 kPa to 354 kPa The temperature is kept constant What new volume does the gas occupy?
8. Two cubic meters of a gas at 30 degrees Celsius are heated at a constant pressure until the volume doubles. What is the final temperature of the gas? 60.
30 cubic meters of argon gas is kept under constant pressure the gas is heated from 10.0 degrees Celsius to 293 degrees celsius what is the new volume of the gas?
8 is the new volume of the gas.
The pressure inside a hydrogen filled container was 2.10 ATM ta 21 degrees Celsius what would the pressure be if the container was heated to 99 degrees Celsius?
sfaas
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
How can water be made to boil at 90 degrees celsius?
By decreasing the pressure with the volume kept constant.
Can water be made to boil at 90 degrees Celsius?

Does doubling celsius temperature double pressure?
Using the Celsius temperature scale, it is not correct. But doubling the temperature using the Kelvin temperature scale, where zero is the absolute minimum gegree possible, will double pressure . p1/T1=p2/T2=constant.
Why if a gas is present at 27 Celsius its volume becomes doubled when temperature increases to 327 Celsius under constant pressure?
pV = nRT we can firstly assume that n (number of moles) and R (gas constant) do not change and as pressure is also kept constant, the temperature must be proportional to the volume. Thus if temperature is increased from 27C (300K) to 327C (600K) and is doubled, the volume must also double.
What is the henrys law constant at 60 degrees Celsius and -10 degrees Celsius?
The amount of any given gas that will dissolve in a liquid at a given temperature is directly proportional to the partial pressure of that gas.
Can ordinary water be boiled in 95 degree Celsius or 105 degree Celsius?
pure water (with no impurities added ) can only boil at 100 degrees Celsius , no other temperature . But if we add impurities to it than the temperature at which the water will boil can increase or decrease. Another point is that when we increase or decrease the atmospheric pressure, the temperature at which ordinary water boils (i.e.100 degrees Celsius) can also increase or decrease.
What is the formula for finding pressure?
I suppose you mean the formula for the variation in pressure. The simplest expression of this is, at a fixed temperature,and for a given mass of gas, pressure x volume = constant. This is known as Boyle's Law. If the temperature is changing, then we get two relations: 1. If the pressure is fixed, volume = constant x temperature (absolute) 2. If the volume is fixed, pressure = constant x temperature (absolute) These can be combined into the ideal gas equation Pressure x Volume = constant x Temperature (absolute), or PV = RT where R = the molar gas constant. (Absolute temperature means degrees kelvin, where zero is -273 celsius)
If the density of ethanol is 0.7890 kg per liter at twenty degrees Celsius what is the density at fifteen degrees Celsius?
Assuming constant pressure, the answer is:density = 0.789 x 20/15 = 1.052 kg/litre
When the pressure on a gas increases at constant temperature its volume?
decreases
