If a car is traveling at 43.0 miles per hour, contains 3 gallons of gas, and gets 22.5 miles per gallon, can it travel to a station 114.9 km away? If so how many hours will it take? How much gas (if any) is left upon arrival? If not, how far will it go before it runs out of gas? How much more gas would it need to reach the destination?

A chemical engineer must report the average volume of a certain pollutant produced by the plants under her supervision. Here are the data she has been given by each plant: plant volume of pollutant Pitt 8.1 L Oglala Platte 19.5 L 5.0 L What average volume should the chemical engineer report? Be sure your answer has the correct number of significant digits.

Two identical balloons are filled to the same volume, one with air and one with helium. The next day, the volume of the air-filled balloon has decreased by 4.5 %.   By what percent has the volume of the helium-filled balloon decreased? (Assume that the air is four-fifths nitrogen and one-fifth oxygen, and that the temperature did not change.) Express your answer using two significant figures.

I need both of these questions answered.

You and your friends are having lunch together and complaining about the cold weather. Kathy begins telling about her spring break trip to warm, sunny Spain. She starts to laugh when she tells the group that she was frustrated when she awoke on the first day to an outside temperature of 18° and a predicted high of 24°. Kathy was laughing because in Spain temperatures are measured in Celsius. What was the predicted high in Fahrenheit? > View Available Hint(s) O75.2 °F 6.2 °F 100.8 °F O75 °F

Question 11 please

Purifoy All changes saved 8. Answer the question below. Use the rubric in the materials for help if needed. A sample of gas is kept at 5 atmospheres, 25°C, and takes up 3 L. If the gas is cooled, the volume changes to 1.5 L and the pressure changes to 4 atmospheres, what is the final temperature in degrees Celsius?

Your baby brother is toddling around the house, playing with a toy balloon. You decide to teach him something about physics, so you take the balloon away from him and hide it in the freezer. (His cries are enough to convince you that he is excited about this learning experience.) a) If the temperature inside your house is 25° Celsius, while the temperature inside the freezer is -10° Celsius, then by what percentage will the volume of the balloon change? We will take the pressure inside the balloon as constant. When you put the balloon in the refrigerator, it will shrink. (Try it and see!) c) Sketch a p-V diagram for the gas inside the balloon as it cools inside the regrigerator. Label the axes as completely as possible according to the given information.
