If 14.00 mol of helium gas is at 10.0o C and agauge pressure of 0.350 atm, calculate (a) the volume of the helium gas under these conditions (b) the temperature if the gas is compressed to precisely halfthe volume at a gauge pressure of 1.00 atm

The system described below is in the xy plane: m₁ = 6.5 kg at the coordinates x = 1.0 m and y = 6.0 m; m₂ = 5.5 kg at the coordinates x 2.0 m and y = 8.0 m and mg₃ = 8.0 kg at the coordinates x = -3.0m and y = -5.0 m. Make the graphical representation of each of the masses of the system. Determine the position of its center of mass and place it correctly in your graphical representation.

(a) How many atoms of helium gas fill a spherical balloon of diameter 30.6 cm at 23.0°C and 1.00 atm? Enter a number lationship between pressure, volume and temperature for an ideal gas? atoms (b) What is the average kinetic energy of the helium atoms? (c) What is the ms speed of the helium atoms? km/s
