B. The apple from the bottom will hit the ground earlier. This is because an increase in height causes an increase in the time that the object will fall, and therefore will affect the final velocity of the falling object. Moreover, the reduction in velocity due to friction from the air should also be considered.
Lithium Chloride releases 37 kJ of energy per mole when dissolved in water.
Energy released = 0.25 x 37
= 9.25 kJ
= 9,250 J
Temperature change of water may be calculated using
ΔH = mCpΔT
Cp = 4.18 J/g
ΔT = 9,250 / (200 x 4.18)
ΔT = 11.1 °C
Your car is performing a transformation of energy of:
Chemical energy to Mechanical energy
The chemical is the gasoline which is then converted to fire as the car runs thus creating the movement of the car which is mechanical energy.
