<span>At higher altitudes (and thus lower atmospheric pressures), water boils at a lower temperature. This is because the lack of vapor pressure at that altitude doesn't constrain the speed of the molecules with barometric pressure. Therefore, the water begins boiling at a lower temperature. This is often a disadvantage because even if the water is boiling, it won't be hot enough for meals (which is why heat and temperature are distinct). That's why we have pressure cookers, which manage to keep a stable boiling point.

Answer:
Light demonstrates wave-like and particle-like characteristics
Explanation:
Light itself is a wave but under circumstance it will present particle-like charcteristics. This is called wave-particle duality :)
The question is incomplete, here is the complete question:
A murexide soution has a concentration of and an absorbance of 1.850 and the path length is 1 cm. What is the molar absorptivity of the solution?
<u>Answer:</u> The molar absorptivity coefficient is
<u>Explanation:</u>
To calculate the molar absorptivity coefficient, we use the equation given by Beer-Lambert law, which is:
where,
A = absorbance = 1.850
= molar absorptivity coefficient = ?
C = concentration of the solution =
l = path length = 1 cm
Putting values in above equation, we get:
Hence, the molar absorptivity coefficient is
