Can an ether form hydrogen bonds in the same way as does an ester
belka [17]

Yes, an OH group from ethanol can form a hydrogen bond to the ether O atom in the same way as it can do so with the single-bonded O atom in the ester.

The O atom in the carbonyl group of the ester can also form H-bonds with ethanol.

5) Some students believe that teachers are full of hot air. If I inhale 2.2 liters of gas at a temperature of 180 C and it heats
ahrayia [7]

Given :

If I inhale 2.2 liters of gas at a temperature of 180 C and it heats to a temperature of 380 C in my lungs.

To Find :

The new volume of the gas.

Solution :

Since, their is no information about pressure, so we will assume that pressure is constant.

We know, relation between temperature and volume in constant pressure is :

\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

Putting all given values in above equation, we get :

V_2 = \dfrac{V_1\times T_2}{T_1}\\\\V_2 = \dfrac{2.2\times (180+273)}{(380+273)}\\\\V_2 = 1.53 \ liters

Hence, this is the required solution.

A liquid boils when its vapor pressure equals the pressure of the atmosphere.
JulijaS [17]
The answer is true. A liquid boils when its vapor pressure equals the pressure of the atmosphere. At this point, vapor can now readily escape from the liquid phase because it has an equal pressure now with its surrounding which, basically, is in the vapor phase.
