What else can I help you with?
What tract carries sensory impulses from the lower limbs and inferior body trunk?
The spinothalamic tract carries sensory impulses related to pain, temperature, and crude touch from the lower limbs and inferior body trunk to the brain.
What tract conveys nerve impulses for crude touch and pressure?
spinothalamic, it is a somatosensory pathway
How hot does it have to be for crude oil to burn?
Crude oil can ignite and burn at temperatures above 150°C (300°F). The exact temperature can vary depending on the specific composition of the crude oil.
How much does 1 liter of crude oil weigh?
The weight of crude oil can vary depending on its density and temperature, but on average, 1 liter of crude oil weighs approximately 0.85 to 0.87 kilograms.
Can crude oil be a liquid or a gas?
Crude oil is typically a liquid at room temperature and pressure. However, when brought to the surface, some volatile components may evaporate, turning it into a gas.
Why different fractions of crude oil are collected at different temperatures?
Because crude oil is a mixture of different chemicals - mainly hydrocarbons - that have different evaporation temperatures. Roughly speaking, when the crude is heated, its temperature rises until it reaches the lowest vaporisation temperature. The temperature then remains more or less steady as the heat input is used as the latent heat of vaporisation for the relevant compound. When [almost] all of that compound has evaporated, the temperature starts rising again until it reaches the next varorisation temperature, and so on.
Can crude oil can be a liquid or a gas?
Crude Oil is a liquid.
What is the speed of sound in crude oil?
The speed of sound in crude oil can vary depending on factors like temperature and composition. Typically, the speed of sound in crude oil ranges from 1,450 to 1,550 meters per second.
What temperature does crude oil burn at?
Crude oil will typically start to ignite and burn at around 410 to 440 degrees Celsius (770 to 824 degrees Fahrenheit). However, the exact temperature can vary depending on the specific properties of the oil and the conditions in which it is burning.
Can Crude oil ignite?
Yes, crude oil can ignite and burn if exposed to a sufficient heat source, such as a flame or spark. The ignition temperature of crude oil varies depending on its composition, but typically ranges from around 400 to 600 degrees Fahrenheit. Once ignited, crude oil can burn vigorously and release heat and smoke.
What temperature does crude oil evaporate?
Since crude oil contains a variety of hydrocarbon components of different molecular weights, there is no single evaporation temperature. As crude oil is heated the lower molecular weight components boil off first. At temperatures above 650°F the crude oil will begin the process of "cracking" in which the larger components thermally degrade into smaller components. If crude oil is heated in this manner in the absence of oxygen, a final solid product called petroleum coke will be left behind, which consists of carbon, as well as the other impurities in the crude oil that were not removed such as sulfur, vanadium, etc.
Is crude oil hot?
Crude oil is typically stored underground where temperatures are relatively constant, so it is not inherently hot. However, during extraction and transportation, friction and pressure can cause the oil to heat up.
