A clown at a birthday party has brought along a helium cylinder,
with which he intends to fill balloons. When full, each balloon
contains 0.00420 m^3 of helium at an absolute pressure of 1.20 x
10^5 Pa. The cylinder contains helium at an absolute pressure of
1.60 x 10^7 Pa and has a volume of 0.00220 m^3. The temperature of
the helium in the tank and in the balloons is the same and remains
constant. What is the maximum number...

Fun with a helium balloon A loosely filled balloon contains 4.5 liters of helium gas at atmospheric pressure (PA = 101 kPa) and room temperature T = 20 C. The gas in the balloon is then heated to body temperature, 37 C, by a student. (a) The pressure inside the balloon changes very little during the heating process. What is the change in the volume of the balloon? (b) How much work does the expanding balloon do on its environment?...

For the density of air, please use 1.29 kg/m^3, and for Helium,
use .179 kg/m^3
Part A How much additional mass (payload) could this balloon lift? You should assume the balloon's skin, plus other parts of the balloon's structure have a total mass of 930 kg Note however that this number does NOT yet include the mass of the helium filling the balloon, which you will...

12) Consider a party balloon filled with helium with a small mass m hanging from it, as depicted in Figure 2. The balloon can be approximated as a sphere with volume V = 0.035 m. The mass of the rubber and string (i.e. the balloon's mass when it is not filled with helium) is 0.0025 kg. a) If the balloon with the mass hanging is floating in equilibrium, what is the value of the hanging mass? Suggestion: Write Newton's Second...

(a) At 20.5°C, the radius of a solid aluminum sphere is 6.50 cm. What is the increase in the sphere's radius if it is heated to 300°C? Assume α = 22.2 ✕ 10−6 K−1 and β = 66.6 ✕ 10−6 K−1. (b) An 40-ft3 scuba tank is filled with air at room temperature (20°C) so that the gauge pressure is 2985 psi. The tank is forgotten in the Sun for hours, and the tank's temperature reaches 121°F. Ignore the slight...

A blackened, solid copper sphere that has a radius equal to 2.5 cm hangs in an evacuated enclosure whose walls have a temperature of 20°C. If the sphere is initially at 0°C, find the initial rate at which its temperature changes, assuming that heat is transferred by radiation only. (Assume the sphere is a blackbody emitter.)
