How long do fingerprints last on different surfaces? Fingerprints have been developed on porous surfaces (papers, etc.) forty years and later after their deposition. On non-porous surfaces, they can also last a very long time. The nature of the matrix of the latent print will often determine whether it will survive environmental conditions. How do […]

Where are lipids found in food?
Where are lipids found in food? Introduction. In foods, lipids are mainly found in the form of triacylglycerols (triacylglycerides) (TAG), which make up to 99% of lipids of plant and animal origin (Fennema, 1996). Phospholipids (PL) are important structural lipids in foods and cell membranes. Where are lipids and oils found in a plant? Essential […]
Does a microwave use nuclear energy?
Does a microwave use nuclear energy? Microwave ovens use radiation, but not nuclear radiation. However, “microwaves don’t have enough energy to cause biological damage as we think x-rays do.” What is a safe distance from microwave oven? 1.5 meters Can you get cancer from using a microwave? No. Microwave ovens Do Not cause cancer. There […]

Why is entropy of reversible process always zero?
Why is entropy of reversible process always zero? The entropy of various parts of the system may change, but the total change is zero. Furthermore, the system does not affect the entropy of its surroundings, since heat transfer between them does not occur. Thus the reversible process changes neither the total entropy of the system […]
Does 4 cups of boiling water have the same thermal energy as 2 cups of boiling water?
What are the 3 types of thermal energy transfer?
What are the 3 types of thermal energy transfer? Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer […]
