Answer:
A suction bulb or pipette pump to suction the sample.
Explanation:
There are different types of pipettes that can be used in a laboratory:
- Volumetric pipette-used to transfer a specific calculated amount of liquid
- Graduated pipettes-used to transfer different calculated amounts of liquid from one container to another.
- Micropipettes-used to transfer small amounts of liquids
- Pasteur pipettes- just like micropipettes, pasteur pipettes are used to transfer small amounts of liquids, but manually. They are also called droppers.
D. More collisions occur and the time required for the reaction decreases
This happens because according to collision theory, when energy (in this case, thermal energy) is applied to particles, they move/vibrate more quickly.
Bose Einstein condensation occur at temperature very close to absolute zero i.e 273.15 degrees centigrade.. Under such conditions, large quantity of Boson occupies the lowest quantum state, at which point microscopic quantum phenomena becomes apparent macroscopically. A BEC is formed by cooling a gas of extremely low density about one hundred thousandth the density of normal air, to ultra low temperature.
