Explanation:
<em>Beakers are the standard vessel used in chemistry. They come in all sizes including 5 milliliter (ml) flasks and flasks of many liters (L). Much like a cup or a mug, they consist of a cylinder, usually glass, with a flat bottom made to hold liquid. Beakers may or may not have a pour spout although they usually do.</em>

Answer:
The reason the compressed air gets cold after being used is due to a process known as adiabatic cooling, a property of thermodynamics. A gas, initially at high pressure, cools significantly when that pressure is released. The compression needed to turn a gas to liquid allows a large amount of gas to fit in a relatively small space, and when that gas is released to a large space, it rapidly expands to fill the space.
Answer:
During Diffusion, molecules move from areas of high concentrations to areas of low concentration.
Diffusion does not require energy
Answer:
O: Type O individuals can donate blood to anyone, because their blood has no antigens. However, they can only receive blood from other type O individuals (because blood with any antigens is seen as foreign).
Due to photosynthesis, plants convert Sunlight and Carbon Dioxide into Oxygen. All living things breathe in this gas (Oxygen).
