What happen if heat is applied at the bottom of a test tube containing liquid on it?
You should never point the open end of the test tube when heating liquids toward yourself or others for your own safety. Liquids inside the test tube when heating may release some gases and might affect someone when you point the open end of the test tube to them. when heating the test tubes, position it diagonally and move it slowly sidewards so we can prevent cracking or breaking of the test tubes if directly positioned on fire.
What will happen to the transformer if the rated voltage is applied to the winding during short circuit test?
the winding would burn....
Why is heat applied in Benedict's test and not alcohol emulsion test?
In Benedict's test, heat is applied to help facilitate the redox reaction between reducing sugars and the copper (II) ions in the Benedict's reagent, leading to the formation of a colored precipitate. In the alcohol emulsion test, the presence of lipids is indicated by the formation of a white turbidity or opaque layer when lipids are mixed with alcohol and water, and heat is not necessary for this observation.
You are provided with a test tube of water, a piece of wire gauze, an ice cube and a Bunsen burner. Describe an experiment which you can carry out to demonstrate that water is a poor conductor of heat?
Place the ice cube under the wire gauze at the bottom of the test tube. Heat the mouth of the test tube now you can observe the ice cube melting slowly because the heat at the top of the test tube won't move to the bottom but moves higher.

What will happen to the transformer if double the rated voltage is applied to the winding during the open circuit test?
no voltage will be induced on the secondary side of the motor as the windings will become saturated.
How can I effectively loosen wood glue?
To effectively loosen wood glue, you can use heat or a solvent. Heat can be applied using a heat gun or a hair dryer to soften the glue, making it easier to remove. Alternatively, a solvent like acetone or vinegar can be applied to dissolve the glue. Be sure to follow safety precautions and test a small area first to ensure the method does not damage the wood.
Why do we have to heat the test tube in a 45 degree manner?
If you heat the test tube from the bottom, any liquid can turn into a gas. ... Heating the tube at an angle reduces the pressure on the heated substances again allowing the gases to escape harmless into the air.
Why should a thermometer not touch the sides of the test tube and should be placed in the middle?
If you place the thermometer so it touches the sides of the test tube, you are measuring the temperature of the test tube, not the substance in the test tube. So, in order to get an accurate reading of the substance, do not touch the sides of the test tube with the thermometer.
Which test is applied by the courts in cases related to suspect classifications?
Strict scrutiny test
