Answer:an ice cube melting ∆H=+ve
nail polish remover quickly evaporating after it is accidentally spilled on the skin ∆H=-ve
gasoline burning within the cylinder of an automobile engine ∆H=-ve
Explanation:
In an endothermic process, such as the melting of an ice cube, heat is absorbed from the surrounding. The enthalpy change is positive. The evaporation a nail polish and burning of gasoline are exothermic processes which lead to the release of heat to the surrounding. The sign of the enthalpy change in both cases is negative.
Answer:
Prevailing winds
Presence of mountains
Seasonal winds.
Explanation:
Prevailing winds:
Prevailing winds is the wind that blows across an area or surface over time. It affects the amount of precipitation. If winds blows inland from water bodies such as oceans the amount do precipitation will be high because they carry more water vapor than the winds that blow over land.
Presence of mountains :
Mountain ranges affect precipitation too.The windward side of the mountain, which is the side the wind hits has higher precipitation while the land on the other side of the mountain, leeward side, will have little precipitation.
D. Lithium or Li has the smallest ionization energy of those listed with an energy of 5,3917.
