The heat added represents an energy change is the true statement regarding the physical change of liquid water boiling into steam.  

Explanation:

         Physical change is the change of substance without affecting its composition. Likewise, water changes into steam when boiling reveals physical change activity. Water that reaches the boiling point has characteristics like liquid form, bubbles, and denser vapors.  

          This is because when heated, the water molecules receive extra energy from a heat source, vibrate and move faster. Simply, energy changes occur in water particles while heating. If the boiling does not stop, the process continues until all the water turns into gas.  

a The heat added represents an energy change.

Explanation:

i just took the test

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
