Answer:
2. The temperature doubles.
014) 48.6 J
015) 13,700 J
016) 5.94×10⁻²¹ J
Step-by-step explanation:
PV = nRT
P and n are constant.
nR/P = k
V/T = k
If the volume doubles, the temperature also doubles.
014) The kinetic energy per atom is:
KE = 3/2 kT
KE = 3/2 (1.38×10⁻²³ J/K) (21 + 273) K
KE = 6.09×10⁻²¹ J
The total kinetic energy is:
KE = (6.09×10⁻²¹ J) (7.99×10²¹)
KE = 48.6 J
016) The kinetic energy per atom is:
KE = 3/2 kT
KE = 3/2 (1.38×10⁻²³ J/K) (14 + 273) K
KE = 5.94×10⁻²¹ J
015) The total kinetic energy is:
KE = (5.94×10⁻²¹ J) (3.82 mol) (6.02×10²³ atom/mol)
KE = 13,700 J
