Question

part a
after reading the scenario about zaras hot soup, which of the
a energy was created in the system.
b the soup gained more energy than the spoon lost.
c the spoon and soup both gained energy.
d the spoon gained energy, and the soup lost the same amount of energy
part b
which of the following pieces of evidence would best support the claim you chose in part a. choose two pieces of evidence
a the distance zaras mom had to walk to bring her the hot soup.
b the temperature of the spoon and soup after the spoon is put into the soup.
c the type of bowl zaras mom served her soup in.
d the time it took for zara to speak to her grandparents.
e the temperature of the spoon and soup before the spoon is put into the soup.
part c
based on the claim from part a and the evidence in part b, which of the following would correctly justify why the evidence
a according to the law of conservation of energy, the spoon created energy when zara moved it.
b according to the law of conservation of energy, energy was transferred from the cold air to the spoon.
c according to the law of conservation of energy, the soup created energy when it was microwaved.
d according to the law of conservation of energy, energy was transferred from the soup to the spoon.

Explanation:

Step1: Aplicar ley de conservación de la energía

La energía no se crea ni se destruye, solo se transfiere. Cuando una cuchara fría se mete en sopa caliente, la sopa transfiere calor (energía) a la cuchara.

Step2: Analizar opciones de evidencia

Para apoyar que la sopa transfiere energía a la cuchara, se necesitan los datos de temperatura inicial y final de la sopa y la cuchara.

Step3: Justificar con ley de conservación

La ley de conservación de la energía dice que la energía transferida de la sopa a la cuchara es igual a la energía que la sopa pierde y la cuchara gana.

Answer:

Part A: D. The spoon gained energy, and the soup lost the same amount of energy
Part B: B. The temperature of the spoon and soup after the spoon is put into the soup; E. The temperature of the spoon and soup before the spoon is put into the soup
Part C: D. According to the Law of conservation of energy, energy was transferred from the soup to the spoon
