Homework Answers
Correct answer is b.
According to Charles's gas law, the volume of the gas of given mass is directly proportional to the temperature at constant pressure.
That is, V₁/T₁ = V₂/T₂
Balloon is a closed system , helium atoms move about faster and the volume of the gas increases as it expands and so will collide with the wall of the container (the balloon) more often, this, in turn, increases the pressure inside the balloon. Increasing Temperature increases the total kinetic energy of particles, this causes them to move about faster. This increase pressure also
Balloons are elastic and so can expand in size, the increase in pressure due to helium expanding causes the balloon to increase in size. But here pressure is constant.
So, size increase elastically with fastest movement of particles.

A balloon filled with 35.6 moles of helium has a volume of 856 L at 0.0°C and 1.00 atm pressure. The temperature of the balloon is increased to 43.0°C as it expands to a volume of 967 L, the pressure remaining constant. Calculate q, w, and ΔE for the helium in the balloon. (Given, the molar heat capacity for helium gas is 20.8 J/°C · mol, and 1 L·atm = 101.3 J) (Show your work)

Large helium-filled balloons are used to lift scientific equipment to high altitudes. What is the pressure, in atmospheres, inside such a balloon if it starts out at sea level with a pressure of one atmosphere and a temperature of 10.0 degree C and rises to an altitude where its volume is twenty times the original volume and its temperature is -48DegreeC ? What is the gauge pressure, in atmospheres, in the balloon then? (Assume the atmospheric pressure is constant.)
