They're two totally different tests. The alcohol emulsion test is for fat, and it works because water and oil don't mix. The reaction in the Benedict's test requires heat to work.
It takes 2.46 calories of heat to raise the temperature of one gram of ethyl alcohol. Calories are the energy available from the metabolism of a food.
When heat is added to the water, the molecules move faster. When the water reaches the boiling point (100 Degree Celsius), the water molecules at the surface of the water would break apart with the other molecules and escape (evaporate). When they evaporate, the water molecules changes state and becomes water vapour.
as much as i know, the proteins become denatured, if that helps
The term thermophile means heat loving. It is applied to certain types of bacteria that live in the hot water of a volcanic spring (such as the famous Old Faithful of Yellowstone Park).
Hair dryer is used to create hot air and when this air is applied to plant it will imbibe more water from soil as the rate of transpiration will increase due to heat or hot air
Either consumed or applied to the skin, alcohol increases heat dissipation.
Unplug the device, and sterilize with isopropyl alcohol applied to a washcloth, then allow the alcohol to evaporate. Even turning on the device should kill them due to the heat, but it's a good idea to use alcohol first.
No. Mass does not increase as heat is applied. Mass is the amount of matter in a body and cannot be changed by any physical or chemical process. Volume will increase when heat is applied.
rubbing alcohol has higher specific heat
Alcohol does not absorb heat. It is used, because it evaporates quickly, thus drawing heat away.
It is normally benedicts solution. Add about 1/4 of the total sugar solution to a test tube and heat it in a hot water bath at around 50 degrees C for 5 min. For example, heat 40mL of sugar water (C12H22O11 aq ) with 10mL of Benedicts soluton (copper and sodium salts). If it is a positive test it will turn yellow.
The density of a fluid goes down (becomes less dense) when heat is applied.
alcohol causes dehydration which makes you more vulnerable to heat stroke
Alcohol helps heat escape the body.
Heat goes up
In effect it does. Electricity applied to the heater produces heat. Heat applied to the thermocouple produces electricity.
heat the test tube in inclined position..alcohol is a hydrocarbon
