Qué tipo de sistema es una caja de leche chocolatada sin abrir? Ana considera que es un sistema aislado y en cambio Martina opina que es un sistema cerrado. ¿Cuál de las dos tiene razón y por qué? ¿Y después de tomarla?

The box contains a finite number of chocolates making it a closed system since this number does not change.

After taking the box and opening it to eat some chocolates it becomes an open system that can exchange chocolates with the medium

Explanation:

In thermodynamics an isolated system is a system in which no heat is exchanged with the medium, a closed system is a system where no particular one is exchanged with the surrounding medium.

In this case, the box can exchange heat since the cardboard walls are not insulating, so it is not an insulated system.

The box contains a finite number of chocolates making it a closed system since this number does not change.

After taking the box and opening it to eat some chocolates it becomes an open system that can exchange chocolates with the medium

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
