a spark from a fire work may be very hot but it will not hurt very much because it does not contain much heat energy however even though a cup of tea may not be very hot it can still burn the tongue because it contains a lot of heat energy.
4450 kJ of energy would be released.

The Big Bang event released an immense amount of energy, estimated to be equivalent to about 1045 joules.
The flash of light from a firework is usually milliseconds after the explosion since light travels much faster than sound. The distance can vary depending on the size and type of firework, but typically the flash would be very close to the blast site, within a few meters.
When a substance is cooled to its original temperature, no energy is released. Cooling a substance typically involves removing energy from the substance, but this process does not generate energy. The energy removed is used to lower the temperature of the substance.
They usually come with a 1500W setting.
