What is Gellan Gum? Gellan gum is a water soluble, high molecular weight polysaccharide gum that is produced through the fermentation of carbohydrates in algae by the bacterium Pseudomonas elodea. This fermented carbohydrate is purified with isopropyl alcohol, then dried and milled producing a powder.
Specific heat capacity. When objects of different temperature are brought together, and heat is transferred from the higher-temperature objects to the lower-temperature objects, the total internal energy is conserved.
Electrical energy = Volts x Amps x time = Electrical Power x time. Therefore: Heat energy = mass x specific heat capacity x temperature rise = VIt = Power x time. Example problem A 50 W heater is used to heat a 2 kg block of aluminium.eat energy input = 50x10x60 = 30 000J Heat energy gained by aluminium = 2 x specific heat capacity x 15 = 30 000J Specific heat capacity of aluminium = 30 000/30 =1000J/(kgoC) Notice that the time (10 minutes) has been converted into seconds.
