The discovery of a very early form of helium supports the big bang theory because

Explanation:

The primitive elements are hydrogen and helium, today a 73% is hydrogen and 25% is helium. All this is comming from the first 3 minutes of the Big Bang, according to scientists. Also, helium functioned as the fuel of stars.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
