Akind of foliated metamorphic rock?
the answer is the total amount of energy stays the same.
- according to the conservation law of mechanical energy, for a closed system that entails the presence of just conservative forces ( independant on the pathway between two points), the total mechanical energy of the system (which is the sum of potential and kinetic energies) remains constant (stays the same).
- clearly, the sum at any of the 4 points = 50 j..
c. h20 is reduced
the first equation has h20 part of it, then the second part doesn't have the substance h20
answer: it stays the same.
explanation:we should use the law of ideal gas to solve this problem: pv = nrtwhere, p is the pressure (atm), v is the volume (l), n is the number of moles, r is the general gas constant (0.082 l.atm/mol.k), and t is the temperature (k).for the same gas and in this problem; n and r are constants.the variables are p,v and t.for the two different cases (1& 2): p₁v₁/t₁ = p₂v₂/t₂p₁ = p, v₁ = v and t₁ = t.p₂ = 15.5 p, v₂ = and t = 15.5 t.to get the volume in the second case (v₂): v₂ = p₁v₁t₂/p₂t₁ = (p x v x 15,5 t) / (15.5 p x t) = v.so, the volume will stay the same.
