A spherical balloon with a radius of 10.6 cm is filled with oxygen gas at atmospheric pressure and at a temperature of 13.4°C (a) What is the number of molecules of oxygen in the balloon? 1.28e23 molecules (b) What is the average kinetic energy of oxygen in the balloon? 2.8e-21 Your response differs from the correct answer by more than 10%. Double check your calculations. (c) What is the rms speed of oxygen in the balloon? 472.47 m/s
A spherical balloon is partially blown up and its surface area is measured. More air is then added, increasing the volume of the balloon. If the surface area of the balloon expands by a factor of 7.70 during this procedure, by what factor does the radius of the balloon increase?
6. (4 pts) Air is being pumped into a spherical balloon so that its volume increases at a rate of 100 cm?/s. How fast is the radius of the balloon increasing when the diameter is 50 cm? The formula for the volume of a sphere is V = r.
A cylinder that has a 39.0-cm radius and is 50.0 cm deep is filled with air at 20.5°C and 1.00 atm answer 2 & 3 please. 2. 0/2 points Previous Answers B My Notes A cylinder that has a 39.0-cm radius and is 50.0 cm deep is filled with air at 20.5°C and 1.00 atm as shown in figure (a). The temperature is held constant as a 19.0-kg piston is lowered into the cylinder, compressing the air trapped inside as...
A weather balloon is designed to expand to a maximum radius of 19 m at its working altitude, where the air pressure is 0.030 atm and the temperature is 200 K. If the balloon is filled at atmospheric pressure and 300 K, what is its radius at liftoff? Your response differs from the correct answer by more than 10%. Double check your calculations. m
