2. A sample of neon gas is contained in a bulb at 150 °C and 350 kPa. If the pressure drops to 103 kPa, find the new temperature, in degrees Celsius. NOTE: in the video, temperatures are given on the Kelvin scale. If they had been given in degrees Celsius instead, you would have to convert them to the Kelvin scale -- Gay-Lussac's Law does NOT work if the temperatures are in degrees Celsius. P₁ = 350 kPa P2 = 103 kPa T1= 150°C T2=?

7.The word pour is commonly used in reference to liquids but not to solids or gases. Can you pour a solid or a gas? Why or why not? If either answer is yes, can you give an example?
Torricelli, who invented the barometer, used mercury inits construction because mercury has a very high density,which makes it possible to make a more compact barometerthan one based on a less dense fluid. Calculate the densityof mercury using the observation that the column of mercury is 760 mm high when the atmospheric pressure is1.01 x 105 Pa. Assume the tube containing the mercury isa cylinder with a constant cross-sectional area.
18) What will the temperature of a 2100. mL sample of nitrogen at 526. mm Hg and 42.4oC be, in oC, after it changes to 1290. mm Hg and 3100. mL? Put your answer with 3 significant digits.
These organic solvents are used to clean compact discs : (a) If a 15.00-mL sample of CD cleaner weighs 11.775 g at 208C, which solvent does the sample most likely contain? (b) The chemist analyzing the cleaner calibrates her equipment and finds that the pipet is accurate to +-0.02 mL, and the balance is accurate to +-0.003 g. Is this equipment precise enough to distinguish between ethanol and isopropanol?

On a cold day the atmospheric temperature is reported as 12.9oF. What is this temperature in Kelvin? (Please note that the constant 273.15 is an exact number).
On hot days you may have noticed that potato chip bags seem to inflate even thought they have not been opened. If I have a 250 mL bag at a temperature of 19°C and I leave it in my car which has a temperature of 55°C, what will the new volume of the bag be?
in an experimental solar house, energy from the Sun is stored in barrels filled with water. In a particular winter stretch of five cloudy days, 6.22 GJ (gigajoules, times 10 to the 9th power J) are needed to maintain the inside of the house at 22.0 degrees Celsius. Assuming that the water in the barrels is at 50.0 degrees Celsius, calculate the volume of water required. (Cwater = 4.18 J/g•K), (Dwater = 1.00 g/mL)
You are asked to calibrate a 25.00 mL volumetric pipet. You determine the temperature of your distilled water is exactly 30 degrees celsius. You carefully determined the mass of a clean, dry beaker and found it was 60.1703 g. You pulled the water up to the mark and transferred this to the beaker and found that the new mass was 85.2263 g. What is the actualy volume of the pipet? I tried answering the question above by doing 85.2263 - 60.1703 = 25.056 g I then used 25.056 and multipled it with .995646 (which is the density of water at 30 degrees celsius I believe) The answer I got is 24.947 I am not sure if I am just doing the problem wrong or if it is simply my signifcant figures that are off? Please help :))
A sample of water of a mass of 627.5g and an unknown initial temperature gains 26366 joules. If the final temperature is found to be 75.59 degrees celsius, ehat was the intial temperature?
