I think these two variables are sufficient to completely specify the state.
In an isolated room with air only ,the volume is fixed.Mass ,density and its specific volume can be easily known.
Other thermodynamic properties like entropy, enthalpy etc are also fixed at a given temperature & pressure.
Answer:
E
Explanation:
They will boil at the same temperature.
And remember Christ loves you and
Jesus is coming back soon get right with Christ please
I think the answer would be T<span>ransverse, Longitudinal, & Surface waves.

Answer:
2587.2 J.
Explanation:
From potential energy,
The work done to lift the chain = potential energy of the chain.
W = mgh............... Equation 1
Where W = work done to lift the chain, m = mass of the chain, g = acceleration due to gravity of the chain, h = height of the chain.
But,
m = m'd............... Equation 2
Where m' = density of the chain, d = length of the chain.
Substitute equation 2 into equation 1
W = m'dgh................ Equation 3
Given: m' = 2 kg/m, d = 12 m, h = 11 m, g = 9.8 m/s²
Substitute into equation 3
W = 2(12)(11)(9.8)
W = 2587.2 J.
