What is the difference between the Celsius scale and the Kelvin scale of temperature?
The Celsius scale is an interval scale which means that the difference between 0 deg C and 10 deg C is the same as the difference between 10 deg C and 20 deg C. However, the zero of this scale is arbitrary which means that 20 deg C is not twice as hot as 10 deg C..The zero point of the Kelvin scale is not arbitrary: it is the point at which thermodynamic energy is zero and so the scale more versatile than an interval scale: it is a ratio scale and this means that 20 K is twice as hot as 10 K.
Which is colder 20 Celsius or 25 Celsius?
20 C is colder.
Does sound travel faster in air at 20 Celsius or at 0 Celsius?
20
What is the celsius for -20 degrees?
-20 degrees Fahrenheit converts to -28.9 degrees Celsius.
What does -20 degrees Celsius represent?
-20 degrees celsius is -4 degrees fahrenheit.
Where do you use negative numbers in reality?
There are many examples. On common one is temperatures below zero. If it is -20 degrees outside then we know it is 20 below zero and -20 is a negative number.
What is the state of krypton at 20 degrees celsius?
At 20 degrees Celsius krypton is a gas. You would have to bring the temperature way down to just below -153.22 (yes, negative!) degrees Celsius for krypton to become a liquid, and just below -157.36 degrees Celsius to make it a solid!
What does 20 below zero degrees Fahrenheit equal in Celsius?
-20 deg F = -28.88... deg C
What form does water take at negative 20 degrees Celsius?
Water is a solid at -20 degrees Celsius
What is higher 30 Celsius or 30 Fahrenheit?
30 C is a lot warmer; 30F is just below freezing! You can relate Celsius temperatures with this rhyme; 30 is hot and 20 is nice. 10 is cool, and Zero is ice!
What is minus 20 celsius in below -fahrenheit?
-20ºC = -4.0ºF
What happens to water molecules when temperature changes from 20 to 20 c?
Water freezes and becomes ice at zero degrees Celsius. Also, water has the odd quality that it begins to expand below about 4 degrees Celsius. So the answer is that it would turn into ice and its volume would increase a little.
What is the absolute value of negative twenty?
20 b/c its distance to zero is 20
What does minus 3 degrees mean is it 3 degrees below zero or 3 degrees below 32 degrees Fahrenheit?
minus 3 degrees means that it's three degrees below freezing. So if you are measuring in celsius then it would be -3 degrees since freezing is zero degrees celsius. If you are measuring in Fahrenheit then it would be 29 degrees since 32 degrees is freezing.
What does a negative plus a positive plus a negative number equal?
The answer can be negative, zero, or positive. For example: -15 + 20 + (-10) = -5 -15 + 20 + (-5) = 0 -15 + 20 + (-2) = 3

Is there any difference in -80 degree Celsius and -20 degree Celsius?
-60
