What state would water be at 45 degrees celsius?

At 45 degrees Celsius, water would be in its liquid state. Water turns into a gas (steam) at 100 degrees Celsius and freezes into a solid (ice) at 0 degrees Celsius.

Can something get colder than 0 degrees kelvin?

No, 0 Kelvin is absolute zero, the lowest possible temperature where particles stop moving. It is theoretically impossible for an object to be colder than 0 Kelvin.

What is the scientific measurement for temperature?

The scientific measurement for temperature is typically done in either degrees Celsius (°C) or Kelvin (K). Degrees Celsius is based on the freezing and boiling points of water, while Kelvin is based on absolute zero, the theoretical point at which all molecular motion stops.

As the temperature of a gas or liquid its volume does what?

As the temperature of a gas or liquid increases, its volume typically expands or increases. This is due to the particles within the substance gaining kinetic energy and moving more vigorously, resulting in increased pressure and volume.

Is the statement is correct -273 degree celcius equal to 0 kelvin?

Yes, that statement is correct. Absolute zero, which is 0 Kelvin, is equivalent to -273 degrees Celsius. At this temperature, particles cease to move and have minimal energy.

What is a Kelvin bridge?

A Kelvin bridge is a type of electrical circuit used for measuring very low resistances precisely. It minimizes errors caused by the resistance of the connecting leads by using a Wheatstone bridge configuration with additional connections to compensate for lead resistances. This allows for accurate measurement of small resistances in applications such as precision electronics and material testing.

What substance can attain temperatures below 260 degrees celsius?

Liquid nitrogen can attain temperatures below 260 degrees Celsius. It has a boiling point of -196 degrees Celsius, making it suitable for many cryogenic applications.

Is alcohol in alcohol thermometers toxic?

Yes, the liquid inside alcohol thermometers is typically ethanol, which can be toxic if ingested in large quantities. However, the small amount of liquid in a thermometer is unlikely to cause harm if accidental exposure occurs on the skin. If swallowed, medical attention should be sought immediately.

Is 69 degrees hot?

depends whether you mean Celsius or Fahrenheit scale ;

but it could be hotter in any case.

How much would the freezing point of the water decrease if 4 mol of NaCl were added to 1 kg of water for water and i 2 for NaCl?

The freezing point depression can be calculated using the formula: ΔTf = i * Kf * m, where i is the van't Hoff factor (number of particles), Kf is the cryoscopic constant, and m is the molality of the solution. Given that i for NaCl is 2, and assuming Kf for water is 1.86 °C/kg/mol, the ΔTf for a 4 mol NaCl solution in 1 kg of water can be calculated.

What will Reduce bacteria to a safe level soap toxins water at 82 degrees Celsius or toxins?

Heating water to 82 degrees Celsius will reduce bacteria to a safe level, as this high temperature helps to kill bacteria. Soap can help to remove bacteria from surfaces, but it may not necessarily kill all bacteria present. Toxins may need specific treatments or processes to neutralize them and make them safe.

350 degrees Fahrenheit is how many Celsius?

Start by subtracting 32 from 350 .Then multiply the answer with 5 and divide by 9.

In this case the answer is 176.66 degree celsius.

What is is 98.6 degrees in Fahrenheit?

98.6 degrees Celsius is 209.48 degrees Fahrenheit.

Why is Celsius more used than Fahrenheit?

The unit Celsius is part of the SI metric system of which countries such as China, and countries that compose of Europe primarily use. The United States is the only country that uses unit Fahrenheit when referring to temperature. However, using Celsius to display the temperature of the weather or anything in particular seems much more practical because it's easier to refer to and remember. In Celsius, the freezing point of water is 0 degrees, but in Fahrenheit, it's 32 degrees.

If you have 17 moles of gas at a temperature of 340 degree Kelvin and a volume of 88.98 Liters what is the pressure of the gas?

Assuming the gas is ideal;

pV = nRT

where p = ?

V = 88.98 litres = 88.98 dm3 = 0.089 m3

n = 17 moles

T = 340 K

R= 8.31

Solving for P

P = 539.7 kPa

Convert 16 degrees Celsius to kelvin?

The answer is 289.15 K (approx.). The Kelvin scale starts at absolute zero and is used in scientific laboratories. Celsius is for general use and set 0 and 100 as melting and boiling point of water respectively. To convert from C to K, add 273.15 to C.

How many watt is 180 Celsius?

Watt is a unit of power, while Celsius is a unit of temperature. The two are not directly convertible to each other. Temperature does not have a direct conversion to power (watt) without additional context or information.

How can a person have a temperature of 123 degrees?

A body temperature of 123 degrees Fahrenheit is extremely high and would likely be fatal. This level of temperature is well beyond what the human body can withstand and is not compatible with life. If someone were to have a temperature this high, immediate medical attention would be required.
