Did victor Frankenstein try to create life in a test tube?
no
What happens when you blow over the mouth of a test tube which is half filled with water?
Blowing over the mouth of the test tube will create a decrease in air pressure inside the tube. This decrease in pressure will cause the water in the test tube to rise up due to the higher pressure outside the tube. Ultimately, the water level in the test tube will rise as a result of the change in pressure.
How do you remove oxygen from a test tube?
To remove oxygen from a test tube, one method is to displace it with an inert gas, such as nitrogen or argon. By flushing the test tube with the inert gas, the oxygen is pushed out. Another method is to create a vacuum inside the test tube to remove the oxygen. This can be done using a vacuum pump or a syringe to pull the air out of the tube.

What is used for holding a test tube in place when the tube is hot or should not be touched?
A test tube holder, also known as test tube clamp or test tube rack, is used to hold a test tube in place when the tube is hot or should not be touched. It allows safe handling of test tubes during heating or when conducting chemical reactions.
What happens to the water in the small tube as the water in the test tube absorbs heat?
As the water in the test tube absorbs heat, its temperature increases, causing it to expand. This expansion can create a pressure difference that may cause the water in the small tube to either rise or flow, depending on the setup. If the small tube is connected to the test tube, the heated water may push some of the water in the small tube upward, demonstrating the effect of thermal expansion.
What is the source of error when using a test tube?
A test tube (or sample tube) has no errors.
What is a test tube clamp used for?
Clamping a test tube
What is test tube stand used for?
to hold the test tube
What is used to grip test tube?
Test tube holder
Why should you never shake a test tube containing reagents by covering its mouth with a finger?
You should never shake a test tube containing reagents by covering its mouth with a finger because doing so can create pressure buildup within the test tube. This pressure can cause the test tube to explode, leading to potential injury from flying glass shards and exposure to hazardous chemicals. It is safer to use a stopper or cap to secure the test tube before shaking to prevent any accidents.
What is Hard test tube?
a hard glass test tube is a test tube made out of glass that is almost impossible to break.
