Answer:
C
Explanation
My teacher mentioned that, for instance, Florida tends to be warm, while Central America can have both hot and cold temperatures, and a jacket isn't necessary. I don't recall many details.
Answer: The right choice is (c) application of both a mobile phase and a stationary phase.
Explanation:
Chromatography: This refers to a technique for separating a mixture where the mixture is distributed between two phases at varying rates, one being stationary and the other moving.
Mobile phase: The component in which the mixture is dissolved is referred to as the mobile phase.
Stationary phase: This is an adsorbent medium that remains in place while a liquid or gas passes over its surface, thus remaining stationary.
Consequently, a key characteristic of any chromatography technique involves utilizing both a mobile and a stationary phase.
Response:
The specific heat of the alloy 
Clarification:
Weight of the alloy 
= 25 gm
Initial temperature 
= 100°c = 373 K
Weight of the water 
= 90 gm
Initial temperature of water 
= 25.32 °c = 298.32 K
Final temperature 
= 27.18 °c = 300.18 K
Using the energy balance equation,
Heat released by the alloy = Heat absorbed by the water
[[ - ] = 
( - )
25 × × ( 373 - 300.18 ) = 90 × 4.2 (300.18 - 298.32)
This gives us the specific heat of the alloy.
Response:
Indeed
Clarification:
Earthquakes occur due to the movement of tectonic plates, and when there is a downward shift of these plates, it generates a ripple effect similar to what happens when an object is dropped into water. As the plates descend, the water in the affected area is pulled downward by gravity, but rather than leveling out, it accelerates and gains velocity, subsequently forming a wave. A tsunami becomes evident when the water retreats as it gathers speed; this backward movement, combined with cohesion, causes the water to flow with the displaced water, intensifying the wave, which culminates in a colossal tidal wave we refer to as a tsunami.
