Pentane is the correct answer the prefix pent means 5 so 5 hydrogens
It would have to be physical property * if this helped you in anyway please be sure to leave a thanks:)
Answer:
The likely causes inferred about the differences in times observed are;
1) Slight increase of the vapor pressure of the air immediately above the water surface due to the presence of a lid
2) Variation of heat input due to wind draft that alters the focus of the flame
3) The introduction of impurities into the water from the water source or through the sourcing mediums or containers or during handling of the water
Explanation:
The factors that affect the boiling point of water includes;
1) The amount of heat supplied, to the water
2) Vapor pressure above the water surface
3) Presence of impurities in the water
Therefore, the most likely causes for the difference in the times observed for the water to boil in the order of increasing probability of cause and effect are therefore;
1) Slight increase of the vapor pressure of the air immediately above the water surface due to the presence of a lid
2) Variation of heat input due to wind draft that alters the focus of the flame
3) The introduction of impurities into the water from the water source or through the sourcing mediums or containers or during handling of the water.
