If the humidity of the room is low, the water that contacts the air directly could evaporate and takes some energy from the bulk thus decreasing its temperature steadily. This allows the water to have a lower temperature.
If the container has heat insulation, the rate of temperature drops will decrease too. Water specific heat is higher than the air, so it will need much more energy to increase water temperature.
Answer:
a. BaCl2 is ionic compound.
b. CH4 is covalent compound.
b. MnO2 is ionic compound.
e. H2S is covalent compound.
c. H3AsO4 is ionic compound.
f. CH3OH is covalent compound.
Explanation:
BaCl2, MnO2 and H3AsO4 are ionic compounds due to the presence of ionic bond between the atoms while on the other hand, CH4, H2S and CH3OH are covalent compounds due to the presence of covalent bond between their atoms. In covalent bonds, sharing of electrons occur whereas in ionic bonds, complete transfer of electrons occur from one atom to another atom.
