As the pressure on the surface of a liquid decreases, the temperature at which the liquid will boil
ankoles [38]

Answer: option (1) decreases.


Explanation:


May be you have experienced that: when you go to the beach, where the atmposhpere pressure is greater than the atmosphere pressure in places that are at higher altitudes, the water takes longer to boil. That is because the boiling temperature is greater, and you need more total heat (more time) to permit the liquid to reach that temperature.


The reason why that happens is because substances boil when the vapor pressure (the pressure of the particles of vapor over the liquid) equals the atmosphere pressure. So, when the atmposhere pressure increases, the temperature at which the vapor pressure reaches the atmosphere pressure also increases, and when the atmosphere pressure decreases, the temperature at which the vapor pressure reaches the atmosphere pressure decreases.

Klio2033 [76]

Answer:

0.2298kg of Al

Explanation:

From the equation of reaction

3 moles of Al (81g) is required to mix with 3 moles of NH4ClO4 (352.5g)

Mass of Al required in the fuel mixture for every kilogram (1000g) of NH4ClO4 = 1000×81/352.5 = 229.8g = 229.8/1000 = 0.2298kg
