4

212°F is how many °C?

78% Answer Correctly

100

\(135 {5 \over 9}\)

-100

0


Solution

The formula to convert from F° to C° is:

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (212 - 32)\)

\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)

\(C° = {900 \over 9}\)

\(C° = 100\)


5

An element in the physical state of __________ maintains a constant volume and shape.

86% Answer Correctly

liquid

solid

gas

gel


Solution

An element in a solid state has atoms or molecules that are constricted and do not move freely. Solids maintain a constant volume and shape and exist at a lower temperature than liquids or gases.
