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.

How is Celsius designed?

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 12c equal to in Fahrenheit?

12 degrees Celsius is equal to 53.6 degrees Fahrenheit.

Where in the us does the temp stay between 60 to 70 degrees year round?

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.

How many btus are required to change one pound of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit?

1)This is a 5 part question. The first is realizing that 20F to 32F uses .5BTU per pound per degree. That means it takes 32-20=12*.5=6BTUs to get the ice to 32F. 2)Then you need to know the Latent Heat of Fusion for Ice which is 144BTUs (given). Lets assumes the ice changes from ice to water instantaneously at 32F. 3)Next we calculate the BTUs from 32F to 212F. Which is 1BTU per pound per degree F. 212-32=180 so it take 180BTUS. 4)Next we have to use the Latent Heat of Vaporization of water which will say instantaneously converts water to vapor. This takes 970BTUS (given). 5)Then we calculate the BTUS from 212F to 220F. Which is .5BTUs per pound per degree F which is 220-212=8*.5=4BTUs...... Finally add up all the BTUs and you get 6+144+180+970+4=1304BTUs.

Would it temperature be higher or lower than the temperature of Earth?

It depends on the specific planet in question. Some planets may have higher temperatures than Earth (such as Venus with its extreme greenhouse effect), while others may have lower temperatures (such as Mars which has a thin atmosphere leading to colder average temperatures).

What is the temperature of 250 degrees Celsius on the kelvin scale?

To convert from Celsius to Kelvin, you add 273.15. So, 250 degrees Celsius is equal to 523.15 Kelvin.

What is the freezing point and boiling point of water on the Fahrenheit scale?

According to Fahrenheit scale, freezing point of water is 32 degrees Fahrenheit (°F) and boiling point is 212 °F

What is -27 Fahrenheit degrees is Celsius?

-27 F = -32.78 C

What temperature doess mdf board burn at?

MDF board is composed of wood fibers and resin, so it typically burns at temperatures similar to solid wood, which is around 450-500°F (232-260°C). However, the resin in MDF may emit toxic fumes when burning, so it is important to avoid exposure to smoke from burning MDF.

Is Lithium at room temperature solid liquid or gas?

Lithium is a metal. It is soft and is a nice shiny silvery colour when first cut. It is very reactive.

How do you change celsius to Fahrenheit on safety first ear thermometer model 49501?

To change the temperature unit from Celsius to Fahrenheit on the Safety 1st ear thermometer model 49501, typically you would press and hold the power button for a few seconds until you see the unit symbol flashing. Then use the scan button to switch between Celsius and Fahrenheit and press the power button to confirm your selection. Refer to the user manual for specific instructions for your model.
