Will rainwater and sea water boil at the same temperature?
No, rainwater and seawater will not boil at the same temperature. Seawater has a higher boiling point than rainwater due to the presence of dissolved salts and minerals, which raise the boiling point of the water.
By definition one calory is needed to heat up one gram of water exactly one degree celsius.
So 100 cal will heat 10 g. of water up for 10oC:
Temperature after heating will be 15 oC + 10oC = 25 oC
What is the difference between 480 degrees and minus 60 degrees?
480 degrees is equivalent to one complete revolution (360 degrees) plus an additional 120 degrees. Minus 60 degrees represents a rotation in the opposite direction, resulting in a counterclockwise rotation of 60 degrees from the starting point.
Does c mean Celsius in temperature?
c" is for "centi" as in "centimeters" or "centiliters" - "cm" and "cl". There is 100 centimeters to a meter, just as there are 100 cents to a dollar.
Another answer
In physics, 'c' usually means a "constant", but there is a special "c" that means the speed of propogation of electro-magnetic waves through the vacuum of space - also known as "The Speed of Light" - which is approximately 186 million miles per second or about 300,000 kilometres per second.
It is the 'c' in Einstein's famous equation:
E = mc2
What is the temperature of 128K expressed in degrees Celsius?
The answer is -145.15 C (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 K to C, subtract 273.15 from K.
What is 212 Kelvin in celsius?
212 Kelvin is equal to a temperature of -61.15 degrees Celsius.
- K to C Formula: C = K - 273.15
What is the volume of the gas at 200 degrees c if it is 25 L at 0 degrees c?
Use Charles's Law: V1 / T1 = V2 / T2
Constant pressure must be kept.
Absolute temp. must be used.
T1 = 0 + 273 = 273 degr.K
T2 = 200 + 273 = 473 degr.K
25 L / 273 K = V2 / 473 K
V2 = 25 x 473 / 273 = 43.315 L (final volume).
What is 22.22 degrees Celsius in Fahrenheit?
22.7 degrees Celsius = 72.86 degrees Fahrenheit
- [°F] = [°C] × 1.8 + 32
Could water exist as a liquid in a 50 degree Celsius?
Yes, water can exist as a liquid at 50 degrees Celsius. The boiling point of water is 100 degrees Celsius, so at 50 degrees Celsius, the water is below its boiling point and remains in a liquid state.
What is 96.8 degrees Fahrenheit converted to in Celsius?
96.8 degrees Fahrenheit is equal to a temperature of 36 degrees Celsius.
Is the temperature at noon was 78 degrees an observation or an inference?
That statement is an observation since it directly describes a measurable fact about the temperature at noon without drawing any conclusions or making assumptions.
A temperature of 95.5 degrees Fahrenheit is considered lower than the average normal body temperature of 98.6 degrees. It may indicate hypothermia or another underlying health condition and should be evaluated by a healthcare provider, especially if accompanied by symptoms like shivering, confusion, or weakness.
How do you convert Cecilius into Fahrenheit?
To convert from Celsius to Fahrenheit, you can use the formula: F = (C × 9/5) + 32. Simply multiply the Celsius temperature by 9/5 and then add 32 to get the equivalent temperature in Fahrenheit.
What is the proper way to use a thermometer?
Depends on the kind of thermometer you're talking about. If it's about your own temperature, modern digital ones will measure it through the ear. The old-fashioned ones through the armpit or more reliably, by putting it up the bum.
When measuring the outside temperature, the thing is to measure it in the shade and protect it also against influences by wind or rain.
How do you change to Centigrades on EnviraStation?
To change the temperature unit on an EnviraStation to Celsius, locate the settings menu on the device, and look for an option to change the temperature unit from Fahrenheit to Celsius. Follow the on-screen instructions to select Celsius as the preferred unit of temperature measurement.
Apply the Ideal Gas Law.
n = moles = m/M = 40.4 g / 20.18 g/mol = 2.002 moles
P = ( 150.0 kPa ) ( 1.0 atm / 101.325 kPa ) = 1.480 atm
T = 273.2 + 36.0 = 309.3 K
V = ( n ) ( R ) ( T ) / ( P )
V = ( 2.002 mol ) ( 0.08206 atm - L / mol - K ) ( 309.3 K ) / ( 1.480 atm )
V = 34.33 L <---------[ Answer ]<-----------------------
What is the name for the instrument used to measure temperature?
Most commonly, a thermometer.
Related Information:
Thermometers are used to measure the increase or decrease in the temperature of a system as it gains or loses internal energy.
An alcohol-in-glass thermometer has been the most common personal instrument used to measure temperature. Mercury thermometers are still around but are no longer offered for sale. Today, digital devices are available that scan the forehead or ear. Some other devices used to measure temperature are:
Radiation pyrometer, for extremely high temperatures;
Glass thermometer: mercury or alcohol;
Thermocouple;
Thermistor (thermal resistor)
Bimetallic strip;
Bimetallic spiral;
Platinum resistance thermometer (a resistance detector);
Examples:
A mercury in glass thermometer uses mercury liquid contained within its glass structure to be subjected to heat.
the heat causes the mercury fluid to expand along the glass tube
and the total amount of expansion can be seen as a measure
along the accurate scale of indication.
This is a direct indication of the effects of temperature.
A more complex method of measuring temperature could be a
thermocouple measuring device.
A thermocouple consists of 2 dissimilar types of metal materials in the form of wires , which are joined at 1 end by weld/ fusion.
this single joined end is called the hot junction. The other end of the 2 wires are then terminated at separate junctions;
as in a electronic terminal block. This end of the 2 wires can be called the cold junction.
For most accurate temperature measure, I think temperature sensor is the first choice.
What temp do Fahrenheit and Celsius converge?
The temperature when both the Celsius and Fahrenheit scales are the same is - 40 degrees.
What does 200 C equal in Fahrenheit?
Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32
In this case, the answer is about 392 degrees Fahrenheit.
200 F = (200 - 32 ) x 5/9 C = 168 x 5/9 C
