Why must helium be cooled to 4k before it will condense explain the fundamental process?
The single atoms of helium gas are small, and has small surface area. They must be cooled to 4K before their attractive forces cause them to condense.
Why must the inoculating loop be cooled first before touching a culture?
To avoid killing the test subjects before the test can begin.
Can a gas be returned to a liquid?
Yes. The three common phases of matter, solid, gas and liquid can be achieved by any material provided the right conditions, but different materials exist in different phases under the same conditions. The most common way that changes between these phases are achieved is by a change in temperature (although a change in pressure will also affect the state of matter). If a gas is cooled sufficiently, it will form a liquid. For example, if you set a glass of ice-water out, the outside of the glass will become wet. This wetness is water vapor which was in the air as a gas, but was cooled when it came into contact with the cold glass and condensed on the glass into a liquid. Even gases like Nitrogen, which makes up most of the air around us, can form a liquid, although it must be cooled to −196 °C.
In getting the temperature of tap water why must the bulb of the thermometer be submerged in the water?
Because you need to measure the temperature of water, not the air.
To obtain the station pressure you must normally make corrections for?
Temperature and gravity.

One hundred milliliters of water can dissolve 36 grams of salt at room temperature How much salt must be added to 25 ml of water at this temperature for the solution to reach saturation?

What is meant by saturation temperature and saturation pressure?
The temperature and pressure of the atmosphere must be at that point or in an interval of values for the substance to be saturated. When mixing solutions, the temperature and pressure must be within a certain range for the substance to dissolve.
Why must refrigerant in the suction line be slightly warmer than the saturation temperature?
why must refrigerant in the suction line be slightly warmer than the saturation temperture
What are two things needed to form clouds?
Water vapour and heat. Wind is not necessarily needed to form clouds.
What is meant by the term dewpoint''''?
The temperature to which air must be cooled to become saturated.
How many degrees must the temperature rise to reach 0 degrees if morning temperature in antarctica is -52 degrees F?
52
Why must injection molds must be cooled?
because during the injection molding process, the injection mold temperature will get higher and higher. So need cooling system to keep it suitable temperature.
Gas turns to liquid?
The gas must undergo a process called condensation to turn into a liquid. Molecules in the gas slow down and kinetic energy drops, also dropping the temperature. It most commonly occurs when a vapor is cooled and/or reaches its saturation limit, when molecular density in a gas arrives at its maximum limit.
The critical temperature the core must reach for a star to shine by fusion is?
About 10,000,000K.
What elements exist in liquid form?
Bromine and Mercury at room temperature. All can exist as liquids, but they must be heated or cooled first.
What does a low dew point indicate about the moisture content of air?
The dewpoint is the temperature to which the air must be cooled to become saturated. A lower dewpoint, as in winter, indicates there is less moisture in the air, so the air must be cooled farther before it will become saturated with water. Dewpoint is a combination of many factors, including temperature, humidity, and pressure.
