The correct answer is "c". it is "c" because melting is an endothermic change, and endothermic get's energy from surroundings.

The final volume of methane gas = 2.5 L

Explanation:

Charles' Law: Charles' law states that the volume of a given mass of gas is directly proportional to it's absolute temperature provided the pressure remains constant.

From Charles' law

V₁/T₁ = V₂/T₂

Making V₂ The subject of the equation above,

V₂ = (V₁/T₁)T₂ equation 1

Where V₁ = initial Volume, T₁ Initial Temperature, V₂ = Final Volume, T₂ = final Temperature.

Given: V₁ = 5.00 L, T₁ = 298 K, T₂ = 148 K

Substituting these values into equation 1

V₂ = (5.00/298)149

V₂ = 2.5 L.

Therefore the final volume of methane gas = 2.5 L

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is[tex]v = 5.4 t[/tex]after 28s,[tex]v(28) = 5.4(28) = 15...Read More
