Temperature Conversion Trick (Celsius to Fahrenheit) | Don't Memorise

At what temperature is the temperature in degrees Fahrenheit equal to the temperature in degrees Celsius?

Tungsten, the element used to make filaments in light bulbs, has a melting point of 6192 °F. Convert this temperature to degrees Celsius and to kelvin.

The Rankine temperature scale used in engineering is to the 
Fahrenheit scale as the Kelvin scale is to the Celsius scale. 
That is, 1 Rankine degree is the same size as 1 Fahrenheit 
degree, and 0 °R = absolute zero. 
(a) What temperature corresponds to the freezing point of 
water on the Rankine scale?<img src="https://lightcat-files.s3.amazonaws.com/problem_images/181181819f4d9e35-1668012098790.jpg" alt="" />

(a) 3344 °F

Convert each temperature.
a. 212 °F to °C (temperature of boiling water at sea level)
b. 22 °C to K (approximate room temperature)
c. 0.00 K to °F (coldest temperature possible, also known as absolute zero)
d. 2.735 K to °C (average temperature of the universe as measured from background black body radiation)

At a certain point, the Celsius and Fahrenheit scales “cross,” giving the same numerical value on both. At what tempera-ture does this crossover occur?

Sodium chloride has a melting point of 1074 K and a boil-ing point of 1686 K. Convert these temperatures to degrees Celsius and to degrees Fahrenheit.

Of the 90 or so naturally occurring elements, only four are liquid near room temperature: mercury (melting point = -38.87 °C), bromine (melting point = -7.2 °C), cesium (melting point = 28.40 °C), and gallium (melting point = 29.78 °C). Convert these melting points to degrees Fahrenheit.

The element gallium (Ga) has the second-largest liquid range of any element, melting at 29.78 °C and boiling at 2204 °C at atmospheric pressure.
(b) Assume that you construct a thermometer using gallium as the fluid instead of mercury and that you define the melting point of gallium as 0 °G and the boiling point of gallium as 1000 °G. What is the melting point of sodium chloride (801 °C) on the gallium scale?

SI Units

The International System of Units (SI) is related to the metric system and is based on seven base units.

Physical & Chemical Changes

A physical change involves a change in the phases of matter, whereas a chemical change involves a change in chemical bonds.&nbsp;

Physical Properties

Physical Properties are measurable properties that describe the state of chemical compounds.&nbsp;

Significant Figures: In Calculations

Significant Figures are often involved in chemical calculations.&nbsp;

Scientific Notation

Scientific Notation is used to turn small or large inconvenient numbers into manageable ones.&nbsp;

Density of Non-Geometric Objects

The density of non-geometric objects can be determined using water displacement.&nbsp;

Density

Density represents the mass of an object or compound within a given volume.&nbsp;

Significant Figures: Precision in Measurements

Significant Figures are used to discuss the level of precision in any measurement.&nbsp;

Intensive vs. Extensive Properties

Intensive Properties are independent and Extensive Properties are dependent on the size or amount of substance present

Density of Geometric Objects

The density of geometric objects generally includes spheres, cubes and cylinders.&nbsp;

Significant Figures

Significant Figures are used to determine some level of accuracy within our recorded measurements.&nbsp;

Dimensional Analysis

We use dimensional analysis&nbsp;as a fail proof process to convert from one unit to another.

Chemical Properties

Chemical Properties are observed during chemical reactions.&nbsp;

Temperature is a measure of the amount of average kinetic energy of the atoms in a compound.

Metric Prefixes

Metric Prefixes are “labels” that can be placed in front of base units.&nbsp;

Conversion Factors

Conversion Factors represent ratios or fractions composed of different units.&nbsp;

Classification of Matter

Chemistry is the study of matter and the changes it undergoes, with the atom being its basic functional unit.&nbsp;
