If gas has a volume of 600 ml at 27'c if it is cooled to a temperature of 23'c what will its volume be?
You can use the Ideal Gas Law here: PV=nRT. First you need to find the pressure in the first situation, where V1=600 ml and T1=300 K (temperature is measured in absolute, meaning kelvins, rather than celsius).
P=nRT1/V1
Then, you're looking for the volume in the second situation, so rearrange the Gas Law here:
V2=nRT2/P
Substitute P=nRT1/V1 into this equation to get:
V2=(nRT2V1)/(nRT1)
After some simplification, we reach:
V2=T2V1/T1
And substituting the numerical values gives you:
V2=(293 K)(.600 L)/(300 K)=.586 L=586 L
What else can I help you with?
At what temperature will the r.m.s velocity of the hydrogen molecules be doubled of its value at N.T.P.?
The root mean square (rms) velocity of gas molecules is directly proportional to the square root of temperature. To double the rms velocity from its value at standard temperature and pressure (STP), the temperature must be increased by a factor of 4. Therefore, the temperature needed would be 4 times the temperature at STP, which is approximately 293 K.
The gaseous product of a reaction is collected in a 25.0-L container at 27C The pressure in the container is 300.0 kPa and the gas has a mass of 96.0 g How many moles of the gas are in the container?
You can use the ideal gas law, PV = nRT, to solve for the number of moles, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin. Rearrange the formula to solve for n, n = (PV) / (RT). Convert the temperature from Celsius to Kelvin (27°C + 273 = 300 K), and plug in the values to find the number of moles of the gas in the container.

27C 12C 31C 19C 23C 11C 17CWhat is the range for the following set of measurement?
To find the range of the given set of measurements (27C, 12C, 31C, 19C, 23C, 11C, 17C), first identify the maximum and minimum values. The maximum is 31C and the minimum is 11C. The range is calculated by subtracting the minimum from the maximum: 31C - 11C = 20C. Thus, the range of the set is 20C.

A gas originally at 27C and 1.0atm pressure in a 3.9 L flask is cooled at constant pressure until the temperature is 11C What is the new volume of gas?
Using the equation V1/T1 = V2/T2, we can find the new volume of gas. Plugging in the initial values (V1 = 3.9 L, T1 = 27°C = 300K) and final temperature (T2 = 11°C = 284K), we get V2 = (V1 * T2) / T1 = (3.9 * 284) / 300 = 3.7 L. The new volume of the gas is 3.7 liters.
What is the ideal temperature for proofing bread?
The ideal temperature for proofing bread is around 75-80F (24-27C).
What is the ideal temperature to proof bread?
The ideal temperature to proof bread is around 75-80F (24-27C).
What is the best temperature for proofing bread?
The best temperature for proofing bread is around 75-80F (24-27C). This temperature range allows the yeast to ferment and the dough to rise properly.
