33 degree centigrade equals how many degrees Fahrenheit?
33 degrees Celsius is equal to 91.4 degrees Fahrenheit.
How does the density of water affect its boiling point?
The density of water does not directly affect its boiling point. Boiling point is primarily determined by the atmospheric pressure, which influences the temperature at which a liquid changes into a gas.
What is the ignition temperature of charcoal briquettes?
The mineral graphite has a varying burn point and cant be determined exactly. It has a melt and vaporization point however. Hear I have a little info on graphite...
The mineral graphite is one of the allotropes of carbon. It was named by Abraham Gottlob Werner in 1789 from the Greek γράφειν (graphein): "to draw/write", for its use in pencils, where it is commonly called lead (not to be confused with the metallic element lead). Unlikediamond (another carbon allotrope), graphite is an electrical conductor, a semimetal. Thus, e.g., it is useful in arc lamp electrodes. Graphite is the most stable form of carbon understandard conditions. Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds. Graphite may be considered the highest grade of coal, just above anthracite and alternatively called meta-anthracite, although it is not normally used as fuel because it is hard to ignite.
There are three principal types of natural graphite, each occurring in different types of oredeposit:
- Crystalline flake graphite (or flake graphite for short) occurs as isolated, flat, plate-like particles with hexagonal edges if unbroken and when broken the edges can be irregular or angular;
- Amorphous graphite occurs as fine particles and is the result of thermal metamorphismof coal, the last stage of coalification, and is sometimes called meta-anthracite. Very fine flake graphite is sometimes called amorphous in the trade;
- Lump graphite (also called vein graphite) occurs in fissure veins or fractures and appears as massive platy intergrowths of fibrous or acicular crystalline aggregates, and is probably hydrothermal in origin.
Highly ordered pyrolytic graphite or highly oriented pyrolytic graphite (HOPG) refers to graphite with an angular spread between the graphite sheets of less than 1°. This highest-quality synthetic form is used in scientific research.[3] The name "graphite fiber" is also sometimes used to refer to carbon fiber or carbon fiber-reinforced polymer Graphite

What is lawrencium state at 20 degrees Celsius?
Lawrencium is a radioactive element that is man-made and has a very short half-life. Due to its unstable and radioactive nature, lawrencium does not have a stable state at room temperature like other elements.
Why is the temperature near the window hotter during the summer?
well, during the summer in the north it is warmer. if you do not have thermal-pane windows then it will feel warm or cold depending on the outside temperature.
solution to problem: thermal pane windows.
How many Btu's to heat a room over 100 degrees?
The number of BTUs required to heat a room over 100 degrees would depend on factors such as the size of the room, insulation, outside temperature, and desired indoor temperature. To calculate the exact BTU requirement, you would typically need to know the specific details of the room and use a heating load calculation formula.
The amount of heat required can be calculated using the formula Q = mcΔT, where Q is the heat energy, m is the mass of water (250 grams), c is the specific heat capacity of water (4.18 J/g°C), and ΔT is the change in temperature (85°C - 10°C = 75°C). Plugging in the values, the heat required is approximately 78,750 Joules or 78.75 kJ.
What temperature of the corona?
The temperature of the Sun's corona is millions of degrees Celsius. This high temperature is due to the extreme energy released during solar flares and other solar activities.
What happens when two objects that have different temperatures touch?
Heat will flow from the object that has the higher temperature, to the one with the lower temperature. This will continue until equilibrium is reached, i.e., both objects have the same temperature.
How many substances are solids at 0 degrees kelvin?
Zero on the kelvin scale is the lower limit of the temperature scale, and thus cannot be reached. A chemical at zero degrees Kelvin has no internal energy and thus does not exist.
0 Kelvin is also known as absolute zero.
Laboratory experiments routinely produce temperatures close to absolute zero, but it is impossible to be at 0 K.
The average temperature of the universe is 2.73 Kelvin.
What the difference to 40 degree Celsius to -25 degree Celsius?
The difference between 40 degrees Celsius and -25 degrees Celsius is 65 degrees Celsius. This is because you subtract the lower temperature (-25) from the higher temperature (40) to get the difference.
What keeps temperature on earth from getting too hot or cold?
The Earth's atmosphere acts as a blanket, trapping heat from the sun to keep the planet warm. This process is known as the greenhouse effect. Additionally, the Earth's distance from the sun and its rotation help regulate the temperature by maintaining a balance between heat absorbed and heat released.
What is a temperature scale based on absolute zero?
A temperature scale based on absolute zero is the Kelvin scale. Absolute zero is the point at which particles have minimal kinetic energy. In the Kelvin scale, absolute zero is defined as 0 K, with temperature increments based on the same size as Celsius degrees.
What is a temperature scale based on the freezing and boiling point of water?
freezing water is not good for your body , but boiling water is because , your boiling out all the bad stuff out of the water what i do is boil the water for 4-5 mins , and then , put it in the freezer , and it would be nice and cold : )
#yummy !
What is 38.26 degrees celsius converted to Fahrenheit?
38.26 degrees Celsius is equivalent to 100.87 degrees Fahrenheit.
Are Fahrenheit units the same as Kelvin units?
No, Fahrenheit and Kelvin are two different temperature scales. Kelvin is an absolute temperature scale based on the properties of matter, while Fahrenheit is a relative temperature scale based on the freezing and boiling points of water. They have different zero points and increments.
Celsius is designed with two reference points; The point at which water freezes and the point at which water boils, 0c and 100c respectively. This can be compared to Fahrenheit at 32f and 212f respectively.
What happens to temperature and pressure as depth beneath earths surface increase?
As depth beneath the Earth's surface increases, both temperature and pressure increase. This is due to the weight of the overlying rock and the Earth's internal heat. The increase in pressure and temperature with depth is known as the geothermal gradient.
Does boiling oleander leaves reduce their toxicity?
The oleander plant in its raw state is extremely toxic. However, when properly made into an extract in attains strong immune building properties. Properly making an extract entails much more than boiling leaves. Instructions must be followed precisely and the plant must be handled with care. Just touching the plant can result in toxicity.
Furthermore, in making an extract only Nerium Oleander should be used and one must make absolutely sure that the plant has never been sprayed with any type of pesticides.
Anvirzel is an internationally patented extract of the Oleander plant. Dr. Robert Newman, Chief of Pharmacology at M. D. Anderson Clinic in Houston, Texas performed in vitro research and although it passed Phase I clinical trials, to date there has been no funding available to continue with Phase II.
Below are the proper instructions in making a homemade version of the extract

What is freezing point of sucrose?
The solid form of sucrose is a crystalline powder. The liquid form of sucrose is a thick syrup. The temperature of this transition is called the freezing or melting point and it occurs at 186 degrees C. or 367 degrees F
What is the melting point of scotch tape?
The melting point of Scotch tape is greater than 175 Celsius. However, it loses its sticking power ~100 Celsius. (As measured in an university oven)
What is the absolute zero on the Fahrenheit scale?
Absolute zero on the Fahrenheit scale is -459.67°F. At this temperature, molecules cease to move, and all molecular motion stops.
