Question

Two identical boxes contain helium gas at the same temperature. If Box I contains 3.000 atoms and Box 2 contains 5,000 atoms, which of the following is true? Box I and Box 2 have the same pressure, hut Box 2 has a higher thermal energy. Box I and Box 2 have the same thermal energy, but Box 2 is at higher pressure. Box I and Box 2 have the same pressure, but Box 1 has a higher thermal energy. Box I has a higher pressure and a higher thermal energy. Box 2 has a higher pressure and a higher thermal energy. The weight of a block of unknown material is 1.5 N when measured in air. When you drop the block in water, it floats at the surface. What is the buoyant force on the block? 0 N Less than 1.5 N but not 0 N Exactly 1.5 N Greater than 1.5 N Two identical balloons filled with air arc held underwater, one at a depth of 3 m and the other at a depth of 9 m. How do the pressures felt by the balloons compare? The balloon at a depth of 9 m will feel twice as much pressure as the other balloon. The balloon at a depth of 9 m will feel three times as much pressure as the other balloon, The balloon at a depth of 9 m will feel nine times as much pressure as the other balloon, The balloons will feel the same amount of pressure. We cannot compare the pressures of the balloons without knowing the exact volume of the balloons.

Explanation / Answer

8)

Here ,

as ideal gas equation is

PV = n RT

now, for same temperature and volume ,

the pressure is higher for gas having higher number of atoms ,

and thermal energy = 1.5 * n *RT

Hence, the correct option is

option e) box 2 has higher pressure and higher thermal energy
