Answer:

Calor absorbido, Q = 5023.2 Joules

Explanation:

Dados los siguientes datos;

Masa = 100g to kg = 100/1000 = 0.1kg

Temperatura inicial, T1 = 293.15 K

Temperatura final, T2 = 305.15K

Capacidad calorífica específica = 4186 j/kg.K.

Para encontrar la cantidad de calor necesaria;

La capacidad calorífica viene dada por la fórmula;

Q = mct

Dónde;

Q representa la capacidad calorífica o la cantidad de calor.

m representa la masa de un objeto.

c representa la capacidad calorífica específica del agua.

dt representa el cambio de temperatura.

dt = T2 - T1

dt = 305.15 - 293.15

dt = 12 K

Sustituyendo en la fórmula, tenemos;

Q = 0.1*4186*12

Q = 5023.2

Calor absorbido, Q = 5023.2 Joules

n200080 [17]
The Big Bang theory suggests that the universe is constantly expanding and that stars, galaxies and other entities are moving away from each other. If there were a galaxy moving closer to earth then that would contradict the Big Bang theory since the entities should be moving away from earth and from each other.
