1. What is most likely to happen when an aerosol can is heated?a. The can will be deformed.b. The can will stay the same.c. the can will eventually explode. d. the can will tarnish2. Which of the following phenomena best illustrates Charles’ Law?a. Carbon dioxide being dissolved in water.b. Expansion of the balloon as it is being submerged in hot water.c. Breathing apparatus being used by the patient.d. Leavening agent causing the fluffiness of cake products3. Which of the following samples is highly compressible at high pressure and expandable at hightemperature?a. Oxygen gas b. aluminun sheet c. water d. ice

My question is in the screenshot attached

3. At sea level, specifically in Cagayan de Oro City, the air pressure is Bukidnon. A. immeasurable in C. higher than B. equal to 4. Gases D. lower than are unique compared with solids and liquids because gases A. are fluids B. are easily compressible 5. Which of the following refers to the amount of space gas occupies? C. have no definite shape D. have large densities A. mass B. pressure C. temperature D. volume

According to the Kinetic Theory of Gases, an ideal gas molecule a. has mass, but no volume b. has momentum, but no kinetic energy c. has kinetic energy that depends only on the pressure of the gas d. interacts with only neighboring gas molecules

I need help with question 5, with a little more detailed information

An accident to the head can affect the ability of a person to ventilate.  a. What would happen to the partial pressures of oxygen and carbon dioxide in the blood if a person cannot properly ventilate? b. When a person who cannot breathe properly is placed on a ventilator, an air mixture is delivered at pressures that are alternately above air pressure in the person's lung, and then below. How will this move oxygen gas into the lungs and carbon dioxide out?

13. It is a property exhibited by gas which proves that molecules are always moving. C. It is light D. It is compressible A. It is usually not visible B. It leaks out of the container

Q.34.

A weather balloon has a volume of 52.5 liters at a temperature of 252 K. The balloon is released and rises to an altitude where the temperature is 295 K. O How does this temperature change affect the gas particle motion? A. Gas particle motion increases as the balloon rises. B. Gas particle motion decreases as the balloon rises. C. Gas particle motion stops when the balloon rises. D. Gas particle motion doesn't change as the balloon rises.

According to the Kinetic Theory of Gases, an ideal gas molecule? a. has mass, no volume b. has momentum, no kinetic energy c. interacts with only neighbouring gas molecules.

c IS INNCORRECT. What is the correct answer?

Select ALL the true statements about gas mixtures: A. Gas mixtures behave the same as individual gases do. B. Individual gases behave independently of a mixture. C. Individual gases do NOT contribute to the pressure of a mixture. D. To the pressure of a gas mixture, you should add together all the partial pressures of the individual gases in the mixture. -

Question 46 Choose the situation where a freshly opened bottle of soda pop would "fizz" the least. Assume that all situations are at the same temperature. Hint: As altitude decreases the atmospheric pressure increases. O Flying in an airplane at 35,000 feet of altitude O On top of a mountain that has an altitude of 11,000 feet O At Virginia Beach, Virginia where the altitude is - 0 feet O In Death Valley, CA where the altitude is 282 feet below sea level

2. Use the unrounded k (4289) value given in Question 1 and calculate the total volume of a gas sample if the total sample pressure is 64.3 cm Hg. a. 0.0150 mLb. 15.0 mLc. 0.067 mLd. 66.7 mLExplain your answer

What mass of gas’s left the tube in the scenario?

To do first experiment, pump the gas pump to put gas into the chamber. Only use between 3 and 7 pumps. Increase the temperature to a number you like between 100 K and 500 K, using the fire/ice bucket on bottom. Do not change the chamber width for now, keep it at 10.0 nm (handle on left of chamber). Do not open the chamber to let gas molecules out (handle on top of chamber). Calculating moles using the Ideal Gas Law: PV = nRT, where R = 0.0821 Once you have everything how you like it, you will calculate how many moles of gas are in the chamber, by using the Ideal Gas Law. Recall the Ideal Gas Law requires specific units: atm, L, moles, and Kelvin. Pressure Is indicated by the circular instrument on the top right of the chamber. It is conveniently already in atmospheres. Volume - Determine the volume in nm^3 by multiplying the width, height, and depth of the chamber. Depth is always 1.00 nm and height is always 10.0 nm. Width is adjusted by you to 10.0 nm or 15.0 nm, depending on the…
