Answer:

Because heat is a path function or the energy in transit.

Explanation:

It is not correct to say that a body contains a certain amount of heat because the heat is a path function and not a property of the system. It is the energy in transit which can be encountered only when it crosses the system boundary.

Heat is the energy in transit of a matter which flows by the virtue of temperature difference. The heat energy in a body is stored in the form of kinetic energy of the molecules which gets converted into heat that we know as the responsible factor for the rise in temperature usually.

The hydronium ion concentration in an aqueous solution is [H+] = 5.3 x10-4 M. What is the hydroxide ion concentration? Is this s

VladimirAG [237]

Answer:a

Explanation:

Given

$[H^+]=5.3\times 10^{-4}\ M$

and $pH+pOH=14$

Also $pH=-\log [H^+]$

therefore $pH=-\log (5.3\times 10^{-3})$

$pH=-(-4-\log (5.3))$

$pH=3.275$

Thus $pOH=14-3.275$

$pOH=10.275$

and $pOH=-\log [OH^{-}]$

$[OH]^{-1}=10^{-10.25}$

$[OH]^{-1}=1.88\times 10^{-11}\ M$

As the pH is less than 7 therefore solution is acidic

New stars form from ?

allsm [11]

Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the sun
