The average kinetic energy of an atom in helium gas at temperature T is given by,
K.E=
here, K is botzmann constant =1.38×10⁻²³ m² kg s⁻² K⁻¹
Given, K.E= 6.21×10⁻²¹ J
Substituting the values,
T= 300 K
Therefore, at temperature 300 K the average kinetic energy of the atom in helium gas is 6.21×10⁻²¹ J.
A sand castle that was changed by the ocean waves would be slowly taken away from by the waves and would just become a smooth mound of sand. If Dylan stomped on it then it would still have all of the same sand as before but in a different shape. It would also become a mound of sand but it would have all the same sand as before.
(I don't know if I was supposed to talk about fancy physics stuff so I just gave a basic explanation. I don't know if my answer is really right or not... hope it helped though :))
D), increases. The object absorbs light energy which in turn (energy is energy) usually involves absorbing heat as well.
Answer:
8 m³
282.3 ft³
Explanation:
The volume of each box is width times length times depth:
V = (1 m) (2 m) (1 m)
V = 2 m³
There are four boxes, so the total volume is:
4V = 8 m³
Converting to cubic feet:
8 m³ × (3.28 ft / m)³
= 282.3 ft³
