Exothermic gives off heat/energy and endothermic takes in heat/energy. Exothermic example: a candle flame
Endothermic example: baking bread
In Exothermic, you can expect the surrounding temp. to rise, and in Endothermic you can expect the surrounding temperature to fall.
Hope this helps
Color, heat/temperature, light, it could also start to bubble

<em>36.5 l = 36.5 dm³ = 36500 cm³</em>
<em>10 kg = 10000 g</em>
<em>d = m/V</em>
