Answer:

The answers I think you are looking for is Gasoline or Fuel (chemical energy)

Explanation:

Energy transformation involves change or conversion of energy from one form to another. Having two examples of the same form of chemical energy, convert into two or more types of energy, the best example would be gasoline.

GASOLINE/FUEL → CAR BATTERY + LIGHT BULBS (TRAFFICATOR LIGHT)

<em>(chemical)                     (electrical)               (radiant)</em>

GASOLINE/FUEL → INTERNAL COMBUSTION ENGINE

<em>(chemical)                   (mechanical)</em>

Suppose a snack bar is burned in a calorimeter and heats 2,000 g water by 20 °C. How much heat energy was released?
prohojiy [21]

Heat energy released : 167.2 kJ

<h3>Further explanation</h3>

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

m = 2000 g

c = 4.18  J/ g ° C  

∆t = 20 ° C  

\tt Q=2000\times 4.18\times 20\\\\Q=167200~J=167.2~kJ
