Answer:
if speed or direction changes then there is a change in velocity which is acceleration. Hope this helps!
Explanation:
<span>An exothermic reaction is one in which there is the production of heat whereas an endothermic reaction is one in which heat is absorbed. For the choices above, the answer would be letter B. Ice melting in water and an ice pack turning cold absorbs heat which is why it is an endothermic reaction. Exploding fireworks and gasoline burning gives off heat which is why it is an exothermic reaction.</span>
C) powdered sugar in hot water because the sugar is already broken so it would be more faster than sugar cube in hot water

Answer:</h2><h2>

TRIPLE POINT:</h2>
Triple point is that temperature, at which the substance is found in all three states i.e. solid, liquid and gas. Every substance has different triple point, because Triple point is just above the freezing point and each substance has different freezing and boiling point.
<h2>
_____________________________________</h2><h2>WATER:</h2>
Water has a Melting point or Freezing Point (MP or FP) of 
C or 273K and Boiling point (BP) 
C or 373 K. Since the triple point is just above the MP or FP thus Triple Point of water is 
C or 273.16K.
