From the ideal gas equation,
where n is number of moles, R is Universal gas constant, P is pressure, V is volume, and T is temperature of the gas.
The pressure and volume are inversely proportional to each other at constant temperature and number of moles.
Hence, on decreasing the pressure, the volume will increase.
As the hiker reaches a height of a mountain, the pressure would decrease which results in the reestablishment of equilibrium between gas molecules thus resulting in pushing of bag outwards.
Hence, the bag will expand as the hiker reaches the top of the mountain.
The thermal energy needed to completely melt 9.60 mole of ice at 0.0 C is 57.8 Kj
Explanation
ice melt to form water
The molar heat of fusion for water is 6.02 Kj/mol
Thermal energy = moles x molar heat of fussion for water
=9.6 mol x6.02 kj/mol =57.8 Kj
Ar I did this I think i got it right on edunuty
<span>A. produces as much energy as cell respiration.</span>
Answer:
no
Explanation:
Radium is silvery, lustrous, soft, intensely radioactive. It readily oxidizes on exposure to air, turning from almost pure white to black. Radium is luminescent, corrodes in water to form radium hydroxide. Although is the heaviest member of the alkaline-earth group it is the most volatile.
