Answer:
V=20.2m3
Explanation:
P= 225.4kPa V= ? n= 1.85, T= 22.5+273= 295.5K, R = 8.314
Applying the ideal gas equation
PV=nRT
225.4×V = n×8.314×295.5
V= 20.2m3
Answer: Energy is absorbed, and kinetic energy increases
Explanation: Boiling is the phenomenon in which liquid is converted to gaseous state.
Thus in order to break the inter molecular forces of attraction present in a liquid, energy is required and thus the process is endothermic in nature.
As the molecules absorb energy, the kinetic energy of the molecules increases and they start moving faster and more randomly and convert into gaseous state.
Things go sublime when changing automatically into vapor when it is heated, usually forming a solid figure.
