Answer:

0.112eV/atom

Explanation:

since

p=m/v

then

pv=pv

7.81*0.97=67.81*V

V=7.58/67.81

V= 0.112eV/atom

Rory answered that absolute zero is 0°K. Is this answer correct? Explain why or why not.
Ierofanga [76]

Answer:

Yes, this answer is correct.

Explanation:

Absolute zero is -273.15 degrees celsius

T= Tc+273.15

T is the kelvin temperature

Tc is the temperature in degrees celsius

substitute;

T= -273.15 + 273.15

T=0 K
