Explain why 1 mole of diethyl ether requires less heat to
gizmo_the_mogwai [7]

The quantity of heat required to vapourize 1 mole of a substance depends on the kind of intermolecular forces between the molecules of the substance. Diethyl ether molecules are held together by weak dispersion forces compared to the stronger hydrogen bonding in ethanol. Therefore,  1 mole of diethyl ether requires less heat to  vapourize than is required to vapourize 1 mole of  ethanol.

Intermolecular forces hold the molecules a substance together in a given state of matter. The properties of a substance such as boiling point, melting point etc are dependent on the nature of intermolecular forces holding the molecules of the substance.

Diethyl ether molecules are held together by weak dispersion forces while molecules of ethanol are held together by hydrogen bonds.

Since hydrogen bonds are much stronger than dispersion forces, a greater quantity of heat is required to break the intermolecular hydrogen bonds in ethanol in order to vapourize them than is required to vapourize diethyl ether.

Therefore, owing to stronger intermolecular forces between molecules of ethanol, less heat is required to vapourize than is required to vapourize 1 mole of  ethanol.

The freezing temperatures for water for Celsius and Fahrenheit scales are 0ºC and 32ºF. The boiling temperatures for water are 1
ddd [48]

Answer:

Therefore the required function is

C= \frac{5}{9} (F-32)

Therefore 25°C=57°F

Explanation:

F denotes temperature of Fahrenheit and C denotes temperature of Celsius.

\frac{C-0}{100-0} =\frac{F-32}{212-32}

\Rightarrow C= \frac{100}{180} (F-32)

\Rightarrow C= \frac{5}{9} (F-32)

Therefore the required function is

C= \frac{5}{9} (F-32)

Putting C=25°C in above equation

25=\frac{5}{9} (F-32)

\Rightarrow 25 \times \frac{9}{5} = F-32

⇒45 =F-32

⇒F=32+45

⇒F=57

Therefore 25°C=57°F
