Why is 32 used for Celsius conversions?
The lower benchmark of both the Fahrenheit and Celsius scales is the freezing point of water. In Celsius, this is zero. In Fahrenheit, this is 32 degrees. This difference must be accounted for before conversion.
What are the units of measurements in temperature?
Temperature is almost always stated in 'degrees', but there are several different systems. The differences are: -- the size of the degrees -- where their zero-point is, i.e. where they begin counting. Here are a few examples: Celsius: Zero point is the freezing temperature of water. Boiling point of water is called '100 degrees'. So the size of the degree is 1/100 of the difference. Fahrenheit: Freezing point of water is called '32 degrees'. Boiling point of water is called '212 degrees'. So the size of the degree is 1/180 of the difference. Kelvin: Zero point is 'absolute zero' ... the temperature where the 'thermal' motion of all molecules completely stops. Size of one "Kelvin" is the same as one Celsius degree. Freezing temperature of water is 273.15 Kelvins. Rankine (hardly ever used): Zero point is 'absolute zero'. Size of the degree is the same as Fahrenheit. Freezing point of water is 459.67 degrees Rankine. Reaumur (never used any more): Freezing point of water is called 'zero degrees'. Boiling point of water is called '80 degrees'. So the size of the degree is 1/80 of the difference.
What does the mass number represent?
The mass number represents the weight of the protons and neutrons in Atomic Mass units (AMUs). One AMU is equal to one proton or neutron.The average mass of all isotopes of the element - apex.
What is the boiling point of alcohol in Kelvin?
Alcohol is a class of chemicals, not a single chemical. Each one has a different boiling point. The alcohol that people drink is ethyl alcohol, or ethanol. The boiling point of ethyl alcohol is 78oC. Since we add 273 into the the number while changing it to Kelvin Therefore, 78+273 = 351 in Kelvin.
Why is it incorrect to say the temperature of an object is 25 degrees kelvin?
The units of the kelvin scale are 'Kelvin' not degrees, so the correct way to write it is simply 25k, or 25 Kelvin.
Why is salt is put on the roads on icy weather?
This is called a colligative property. Salt lowers the freezing point of water. Why? Because the molecules (formula units) of the salt interfere with the formation of ice crystals by getting in their way. The more salt, the lower will be the freezing point.
E equals mc2 what does the c stand for?
E=MC2The E represents the units of energyThe M represents the units of massThe C Represents the Speed of LightE=MC2 means Energy equals mass times the speed of light squared. Although this is not 100% correct it is very close!
What abbreviation represents volume units?
UNITS
What does 2 stand for in this decimal 1362?
Without a decimal point it is not a decimal number but the 2 in 1362 represents 2 units
What if your friend is graphing the point (25) . Her first step is to start at the origin and go up 2 units. Is her method correct?
If you mean the point of (2, 5) then the 1st step is to move 2 units to the right of the origin then move 5 units up to locate the given point.
What is the abbreviation of Celsius?
'C'It is also used to mean 'Centigrade'.Celcius is the correct term.There were other centigrade scales used in the past, that subdivide the scale into 100 units (centi-).Celcius scale has 0 at the freezing point of water and 100 at the boiling point of water.
What is M L T in physics?
M L T are the units. M represents Mass, L represents Length and T represents Time. These are the fundamental units and all other units are derived from these three. Example: Velocity is MLT-1
Which expression represents the area?
The area is measured in square units.
What does the 0 represent in 34000?
It represents hundreds, tens and units.
What is the place value of 8 in 98?
It represents 8 units
Which point is 5 units from (1 3) on a coordinate plane?
That depends on the direction of the point in reference to the original coordinate. If the new point is 5 units to the right of (1,3), then the point is (6,3). If the point is 5 units left of (1,3), then the point is (-4,3). And so on.
What is the largest point in metric system?
It has no largest point. They are units of measure. There can be an infinite number of units.
