Answer: The new penny is not pure copper
Explanation:
Density 
is defined as a relation between the mass 
and the volume 
:
Now, we are told the density of pure copper is:
And we are given the mass and volume of the new penny, with which we can calculate its density:
As we can see the density of this penny is not equal to the density of pure copper, hence the new penny is not pure copper.
The RMS of O2 at 17 degrees is calculated as follows
RMs= ( 3RT/m)^1/2 where
R= ideal gas constant = 8.314
T= temperature= 17+273= 290 K
M= molar mass in KG = 32/1000= 0.032 Kg
Rms is therefore= sqrt (3x 8.314 x290/0.032 ) = sqrt( 226036.875
RMs=475.43
The two blocks have the same amount of thermal energy.
<h3>Effect of temperature on different mass objects</h3>
Due to platinum metal, the thermal energy is equally distributed in the whole metal so that's equal distribution the thermal energy of both blocks will be the same so we can conclude that the two blocks have the same amount of thermal energy.
