An odometer is an instrument used for measuring the displacement of a car.

<h3>What is displacement?</h3>

The displacement of an object is the change in the position of the object.

It measures the shortest distance between the final position of an object and the initial position of the object.

<h3>What measures the displacement of a car?</h3>

An odometer is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car in a specified direction.

The heat vaporization for methyl alcohol is 1100 kj/kg. It is 2257 KJ/Kg for water. Thus means that______________.
dusya [7]

Answer: B) Methyl alcohol requires less than half as much energy per kg to evaporate than water does

Explanation:

Latent heat of vaporization is the amount of heat required to convert 1 kilo gram of liquid into its vapor state without change in its temperature.

Heat of vaporization is more for water than for methyl alcohol which means more heat is required to convert from liquid to vapour form.

As the Heat of vaporization for methyl alcohol  (1100) is almost half as that of Heat of vaporization for water (2257) , it means  Methyl alcohol requires less than half as much energy per kg to evaporate than water does.

A substance has a vapor pressure of 77.86 mm Hg at 318.3 K and a vapor pressure of161.3 mmHg at 340. 7 K. Calculate its heat of
zavuch27 [327]

Explanation:

It is given that,

Initial vapor pressure, P₁ = 77.86 mm

Initial temperature, T₁ = 318.3 K

Final vapor pressure, P₂ = 161.3 mm

Initial temperature, T₂ = 340.7 K

We need to find its heat of vaporization. It can be calculated by using Clausius-Clapeyron equation.

ln(\dfrac{P_2}{P_1})=\dfrac{\Delta_{vap}H}{R}(\dfrac{1}{T_1}-\dfrac{1}{T_2})

\Delta _{vap} H=\dfrac{R\ ln(\dfrac{P_2}{P_1})}{(\dfrac{1}{T_1}-\dfrac{1}{T_2})}

\Delta _{vap} H=\dfrac{0.008 314\ ln(\dfrac{161.3}{77.86})}{(\dfrac{1}{318.3}-\dfrac{1}{340.7})}

\Delta _{vap} H=29.31\ kJ/mol

So, the heat of vaporization of a substance is 29.31 kJ/mol. Hence, this is the required solution.
