Whether the statements are yes or no for the conservation of momentum.

Question

Two concrete spans of a 234 m long bridge are placed end to end so that no room is allowed for expansion (Figure a). Each span therefore has a length of L0 = 117 m. If the temperature increases by 17.8 °C, what is the height y to which the spans rise when they buckle (Figure b)? (The coefficient of linear expansion of concrete is 1.20⋅10−51.20⋅10-5 °C−1.)

Monkey D. Luffy, from One Piece can inflate himself like a balloon to a size of 6.98 m3 by inhaling 1.74⋅10^26 molecules of air. If the air is at 20.9 ˚C, the pressure inside Luffy is 101277.062 Pa. kB=1.38⋅10^−23 J/K. The total internal energy of the gas inside Luffy is 1065333.93 J. How fast, on average, is the air molecules inside Luffy traveling at? The average mass of an air molecule (considering the various gasses involved) is 4.51 x 10^-26 kg.

The Dungeons & Dragons spell “Stinking Cloud” fills a 949 m^3 volume of air with a cloud of gas. The pressure of the gas is the same as the air, 101,325 Pa, and is at 29.2°C. There are 2.304x10^28 molecules of gas. What is the total internal energy of the gas?
