What’s the weather like in the other states?

Likurg_2 [28]3 years ago

5 0

Answer:

In weather maps, sharp edges are typically used with cold air. They also point in the direction of the front. So in this picture, the town will be experiencing a drop in temperature (also known as a cold front) as well as a decrease in precipitation.

Hope this helps

The heat of vaporization of 1–pentanol is 55.5 kJ/mol, and its entropy of vaporization is 148 J/K•mol. What is the approximate b

tensa zangetsu [6.8K]

Answer:

375 K

Explanation:

Using the experssion shown below as:

$\Delta G^0=\Delta H^0_{vap}-T\Delta S^0_{vap}$

At vaporization point, the liquid and the gaseous phase is in the equilibrium.

Thus,

$\Delta G^0=0$

So,

$Delta H^0_{vap}=T\Delta S^0_{vap}$

Given that:

$Delta H^0_{vap}=55.5\ kJ/mol$

Also, 1 kJ = 10³ J

So,

$Delta H^0_{vap}=55500\ J/mol$

$\Delta S^0_{vap}=148\ J/K.mol$

So, temperature is :

$T=\frac{Delta H^0_{vap}}{\Delta S^0_{vap}}$

$T=\frac{55500}{148}$

Answer:

The food coloring mixes through the hot water faster than it mixes with the cold water. This is because in hot water, thewater molecules have more energy and are moving faster than the molecules of cold water. This makes it easier for the dye to get mixed throughout the hot water.
