Why is high pressure an important part of the oil extraction process?
High pressure is important in the oil extraction process because it helps to push the oil out of the reservoir and up to the surface. This pressure can come from natural underground formations or be artificially created through techniques like hydraulic fracturing. Without sufficient pressure, the oil would not flow efficiently and extraction would be much more difficult and costly.
Why does flame burn with a conical flame?
When a flame burns, hot gases are produced and these combine with the air to generate heat. Flames get their tongue-like or tear-drop shapes due to the movement of these gases that are influenced by the gravity of the Earth.
How does the refrigarator or freezer work to keep things cold?
Refrigerators, freezers, air conditioners, heat pumps(air and ground source) all work on the principles of refrigeration. Modern refrigerators don't use Chlorofluorocarbons because CFCs are harmful to the atmospheric ozone layer when released. Instead they use various other refrigerants that are now primarily Hydrofluorocarbons. In new refrigerators a gas called HFC-134a, also called tetrafluoroethane is used. HFC-134a turns into a liquid when it is cooled to -15.9 degrees Fahrenheit (-26.6 degrees Celsius). A motor and compressor squeezes the gas (refrigerant). When it is compressed, a gas heats up as it is pressurized. When you pass the compressed gas through the coils on the back or bottom of a modern refrigerator, the warmer gas can lose its heat to the air in the room. According to the laws of thermodynamics: 1) As it cools, the refrigerant will change into a liquid when it is under enough high pressure. 2) Something that is hot will give up its heat to its colder surroundings. The liquid flows through what's called an expansion valve, a small hole that regulates how fast the liquid refrigerant squeezes through. Between the valve and the compressor, there is a low-pressure area because the compressor is pulling the gas out of that side (while compressing it on the other). When the liquid HFC hits a low pressure area it boils and changes into a gas. This is called vaporizing. Remember that the refrigerant boils (or vaporizes) at minus 15.9 degrees F. That is always going to be colder than the surrounding air temperature in the fridge and even the freezer. Therefore, as the refrigerant within the coils (evaporator) passes through the freezer and regular part of the refrigerator, the colder liquid in the coils pulls the heat out of the compartments. This makes the inside of the freezer and entire refrigerator cold. The compressor sucks up the cold gas, and the gas goes back to the compressor to start the process over. A thermostat regulates when the desired temperatures in the cold compartments have been reached by turning the compressor on or off.
An instrument used to start up fire by blowing on hot coal?
A bellows is a common instrument used to blow air onto hot coals to help start a fire. The act of blowing air helps to provide oxygen to the coals and therefore increases the heat, allowing the fire to ignite and grow. Bellows are typically made of wood and leather, and the user squeezes the handles to push air out through a nozzle onto the coals.
Change from gas to solid?
Changing a gas to a solid is dependent on one crucial thing; the material in question! For example, with steel that is in a gaseous state, which requires a substantial and extreme amount of heat {around 3000 Kelvin in the most heat-tolerant ores), needs only a cooling agent to turn directly from gas to solid. This process is primarily done with liquid iron, rather than vaporeal iron, but the idea still is relevant. That process is what allows us to produce ball bearings and mold things. There is of course the second method, which is how "liquid" propane stays a "liquid", even though it boils quite well below the freezing point of water. That method is pressurization. A very large volume of gas is placed into a reinforced container. This container squeezes that great volume into such a small area, the gas acts like a solid; clumping together, even though under normal pressure, it would be floating into neverland. This method works for organic gases and fluids; like butane lighters and propane grills, that boil below temperatures humans are comfortable in.
What type of fossil preserves delicate of an organism after pressure squeezes out liquids and gases?
film
Compressions form when the overlying compresses the organism into a flat layer?
Compressions form when an organism gets buried by sediment, which puts pressure on the remains and squeezes out any fluids. Over time, the sediment hardens into rock, preserving the flattened impression of the organism. This process helps to create fossils known as compression fossils.
What is a force that pushes on or squeezes a material?
Compression is a force that pushes on or squeezes a material, causing it to become denser or reduce its volume. This force is commonly experienced in applications such as compressing gas in a piston or applying pressure to deform a solid material.
What provides the pressure to move blood through the veins and back to the heart?
skeletal muscle contraction that squeezes the blood in the veins.
