At constant pressure a known moles of gas has volume which is directly proportional to temperature (Charle's Law)
Thus V α T
Therefore
V1/V2 = T1 /T2
V1 = initial volume = 10 L
T1 = initial temperature= 280 K
V2 = final volume = 20L
T2 = final temperature = ?
T2 = T1V2 / V1 = 280 X 20 / 10 = 560 K
Thus the new temperature will also doubles up as volume is increased by two times
Because of the motion, the faster the particles move , the higher temperature goes
Answer:
The order of conductivity will be as follows:
> NaBr > Benzoic acid > sugar
Explanation:
ionizes to give one Al and three ions and thus, produces 4 ions.
Sugar does not ionizes and hence does not produce ions.
Benzoic acid is a weak organic acid and ionizes to produce two ions; and .
Sodium bromide is a strong electrolyte and ionizes to produce 2 ions.
As sodium is strong electrolyte, therefore, its conductance will be higher than benzoic acid.
Therefore, the order of conductivity will be as follows:
> NaBr > Benzoic acid > sugar
Answer:
Right
Explanation:
The given parameters are;
The soluble sulfate formed by the metal, M = M₂SO₄
In the galvanic cell formed by the metal M, we have;
The concentration of M₂SO₄ in the left half cell = 50.0 mM = 0.05 M
The concentration of M₂SO₄ in the right half cell = 5.00 M
In the galvanic cell, the metal 'M' will be dissolved into the solution with lower concentration as M²⁺ which is the left half cell, making the cell negative and the solution more concentrated
In the right half cell, the metal 'M²⁺' in the solution will be plated unto the electrode making the solution less concentrated and the electrode in the right half cell will be the positive electrode
Therefore;
The electrode which will be positive is the electrode in the right half cell.
The density would be 1.84 g/cm<span>³</span>
