What is drying precisely? Drying is to evaporate liquid such as water or solvent included in materials by heating. Incidentally, 2540J (J=joules) of heat is necessary to evaporate 1g (g=gram) of water at temperature of 20°Celsius (68°Fahrenheit) and 1 atmospheric pressure. By converting this to time, 0.039g of water can be evaporated every 1 second […]
