Suppose a balloons was laying by the window at night. The next day, when the sun came up, it warmed the gas (air) that was in the balloon. What would be true about the density of the air in the balloon? O It will increase. It will remain the same. O It will decrease. it will decrease for a while, then increase

Amanda discovers that the gauge pressure in her car tires is 2.50 ×105 Pa at a temperature of 35.0oC. The average volume of a single tire at that temperature is 10.0 L. 1.) Find how many moles of gas (air) are in one of Steve’s tires.   2.) Later Amanda travels to a place where the temperature is –40.0oF. She notices that the tires are looking low and estimates that each tire has lost approximately 1.0 L of its volume. What is the gauge pressure in the tire now?

Liquids and solids have densities on the order of 1000 times greater than gases. Explain how this implies that the distances between molecules in gases are on the order of 10 times greater than the size of their molecules?

What is the mass of the helium gas in the previous problem? The molar mass of helium gas is 4.00 g/mol.
