The correct answer is D, the Endothermic Process.
Hope I helped. :)
V₁ = <span>178 mL - initial volume
</span>T₁ = 0 ⁰C = 273K - initial temperature
V₂ = <span>211 mL - final volume
</span>T₂ =? - final temperature
According to Charles's law when pressure is constant the Kelvin temperature and the volume will be directly related:
V₁/T₁=V₂/T₂
178/273=211/T₂
0.65=211/T₂
T₂=324K= 51⁰C
Answer:
I think the answer is chemical energy
Explanation:
<span>Each mole contains Avagodro's number of atoms i.e. 6.023x10^23, so
3 moles x 6.023x10^23 atoms/mole = 18.069x10^23 atoms = 1.8x19^24 atoms </span>
Potential energy (PEI due to gravity = mgh
Where, m= mass of the billboard, g=gravitational acceleration (9.81 m/s^2), h = height
Therefore,
m= PE/(gh) = 175000/(9.81*30) = 594.63 kg
