Answer:
C. 
Explanation:
Molecules with the stronger intermolecular forces are pulled tightly together to form solid at higher temperatures and that's why the freezing point is higher.
Also, molecules with the stronger intermolecular force have greater interaction between the molecules and thus on heating do not boil easily and have high boiling point also.
Thus, melting point and boiling point increases with increase in number of carbon atoms and also increase in intermolecular forces (like hydrogen bonding, if present).
Thus, the compound which is gas at room temperature is <u>because it has least number of carbon atoms and absence of hydrogen bonding.</u>

Answer:
E
Explanation:
burning a substance changes it chemically.
Answer:
High partial pressure of oxygen in the tissues.
Explanation:
Hemoglobin is a protein found in the red blood cells that is responsible for the transportation of oxygen from the lungs to the rest of the tissues in the body. The partial pressure determines whether oxygen is loaded or unloaded into the hemoglobin.
When there is lack of oxygen in our bodies, we experience hypoxia.
Hey there
It may be the lomy soil
Besides the sandy soil ,clay soil can not be used for growing plants or farming
Hope u derived something from this
