Answer: c = 710 J/kg°C or 0.71 J/g°C
Explanation: Heat is expressed in the formula Q = mc∆T. Derive to find the specific heat c. So the formula will become c = Q / m∆T
c = Q / m∆T
= 42600 J / 2 kg ( 55°C - 25°C )
= 710 J /kg°C
Or can be expressed by converting kg to g.
c = 0.71 J /g°C
Explosives are chemicals that have very fast burn rates at different degree.
First the Dynamite:
-The dynamite is an explosive that made from nitroglycerin, and it is a type of the explosive that has a fast burning rate and makes it very strong explosive. Physical shock can make the dynamite to explode and makes it highly dangerous.
-But the fireworks are a class of low explosive, the stuff that used in it is black powder.Because this explosive has a slow burn rate than dynamite that makes it less dangerous and safer than dynamite explosives
-SO although the dynamite and the fireworks are both explosives they have different burn rates which make them totally different in safeness.
